GREAL’s first aerophotogrammetric test flight by UAS over the Roman Villa della Fontanaccia archaeological site (Tolfa, Italy).

Yesterday morning, May 10th 2022, GREAL conducted its first UAS-based aerophotogrammetric test over the Roman Villa della Fontanaccia archaeological site, in the mountains near Tolfa. During two flights, for an overall duration of approximately fourty minutes, initial data were gathered and procedures were validated, towards a research and teaching protocol that GREAL will develop in the next months in cooperation with the “Gruppo Archeologico Romano (GAR).

The test was attended by GAR’s President Gianfranco Gazzetti, by GREAL’s Director Gianluca Casagrande and by UER’s lecturer Alessandra Romano.

Aerial and ground images (the latter in a 360° format) will become part of a periodical data acquisition that GREAL will conduct for documenting GAR’s excavation activities on the site, during 2022-2023. The activity served also as a demo for students of UER’s MOT certificate programme, who could enjoy an onsite visit of the valuable Roman site and also to have a brief hands-on experience of archaeological excavation.    


UER and GREAL at the “Borsa Mediterranea del Turismo Archeologico” at Paestum

Paestum’s archaeological park, in Campania region, Italy, hosts the 2021 edition of the “Borsa Mediterranea del Turismo Archeologico”, a major national event involving research, institutional participation and enterpreneurship in tourism initiatives for historical sites and cultural heritage.

UER’s School of Tourism and GREAL participated to the activities on November 25th and 26th, presenting the academic program for 2022-2023, and opening an information desk about the laboratory’s activities. UER’s delegation included Prof. Luigi Russo, Development and Communication manager Marco Brotto Rizzo, Prof. Alessandra Romano, Prof. Gianluca Casagrande, PhD candidate Roberta Rodelli and Ms. Giulia Vinci (GREAL). During a talk to present several Schools of Tourism in Italy, representatives from different academic institutions exchanged their views on present-day scenarios for tourism and archaeology. With specific focus on the professional opportunities in both areas, all speakers encouraged the numerous students attending the event to keep an optimistic outlook on the future. The birth of new professions, particularly in technological fields and digital humanities, will ensure remarkable opportunities to the most dedicated, motivated and creative students.  




An international research work on geo-history in Spain

A few areas of countryside in the Jaén’s region, Andalucia, Spain, are hosting a fieldwork phase in the context of an international research project. The activity is funded by the Spanish Ministerio de Ciencia y Inovación under the ID PID2019-110225GB-I00. Though national in origin, the program is developed by an international network; it is called ProSiMo, an acronym standing for Proyecto de Sierra Morena and is led by Prof. José Miguel Delgado Barrado, of Jaén’s university.  

The current activity will take place between September 27th and October 4th, 2021 and is conducted by several scientific institutions from different countries, including Spain’s Laboratorio di Experimentación Espacial (UHUM 155 LabE2), la Red Cibeles (Estudios Interdisciplinares sobre Ciudades), both from the Universidad de Jaén, and an Italian scientific group led by prof. Annalisa D’Ascenzo, from the Laboratorio geocartografico “Giuseppe Caraci” (Roma Tre University) and CISGE and including prof. Gianluca Casagrande, from European University of Rome’s GREAL.  

The team at work includes historians, geographers, archaeologists and topographers, all involved in surveys and observations in areas of the Sierra Morena which were involved in a colonization process during the 18th century. More in detail, the study areas include, among others, the current sites of Montizón, Venta de los Santos, Aldeahermosa e Aldeaquemada. The goal of the project is to correlate data documented in the historic cartography to material elements as they can be recognized in present-day landscape. The data acquisition is mainly obtained from drones, fitted with sensors operating in the visible light as well as in the infrared. Their special configuration was developed by Italian company FlyToDiscover upon specifications by GREAL. The two aircraft are managed by two independent groups, one from Italy and one from Spain and daily yield a total of about 1,000 20Mpx and 12 Mpx digital images.  

Depending on operational needs, the photogrammetric “stripes” are directly georeferenced based on the internal positioning system of the drones or, rather, with additional association with ground control points established by topographers through high-accuracy GNSS devices.  

Initial processing of the acquired images has already started; 3D models and ortophotographs are being developed.  

The final goal of the current research is to contribute to a better understanding of how the ancient territory was structured and to allow comparison with different geographical contexts of the same age. With regard to within a framework of public history, ProSiMo aims to support the economy and identity of local communities by developing cultural and touristic itineraries with a special focus on historical geography.

SONARCTC: Mission accomplished

Aug 16, 2021 The Polarquest2021 expedition has successfully completed its seafloor mapping programme today.

The Polarquest2021 expedition has successfully completed its seafloor mapping program today, with its last sonar scanning station in Bockfjorden at 79°5N, 13°4E. The crew, directed by sonar specialist Domink Pałgan and assisted by scientific coordinator Gianluca Casagrande, support engineer Kevin Monneron and environmental science student Elias Meier, started the activity upon leaving Ny Alesund on August 8th, when the deployed a NORBIT Subsea iWBM 200 kHz multibeam echosounder, installed on the right side of the stern platform with its GPS antennas placed on an A-frame above the navigation cockpit. The arrangement proved to be perfectly integrated with the vessel’s structure and internal systems.

The arrangement was developed by shore-team scientific advisor Dr. Aleksandra Kruss (Norbit and Gdansk University), skipper Giovanni Acquarone and technical coordinator Michael Struik.

The multibeam sensor was used to conduct two different types of expeditive surveys: a route scanning during transits along the western and north-western area of Spitsbergen and Nordaustlandet, and a systematic survey of ~25 km2 area Southwestern of Lady Franklinfjorden, Nordaustlandet, down to a distance of approximately 300 metres from glacier Søre Franklinbreen front, beyond the 80th parallel.

The activity allowed to produce new data in partially charted or completely uncharted regions of the archipelago, identifying potential corridors for navigation several points of very shallow waters: These will be reported and to update navigation charts. The scarce availability of such detailed data in the area appeared evident as single depth measurement indicated on nautical maps were often shown by the sonar to correspond to relatively wide and complex morphological structures on the seafloor (e.g. plateaus).

Observations in the Lady Franklinfjorden yielded new detailed data about the features of the sea floor in a previously virtually unknown site and will provide valuable information about the evolution of the local environment with regards to glaciers and their dynamics. Initial results show multiple rows of moraines (up to few meters high “ridges”) oriented parallel to the glacier front,  indicating the position of the glacier front in the geological past. Several lineaments engraved in the outcrops of the bedrock have also been mapped, which are probably associated with an advancing glacier,  showing how powerful ice can really be.

The mapping activity confirms the suitability of small vessels to perform seafloor mapping tasks in shallow seas and particularly in close proximity to coasts, which would prove extremely challenging for larger research vessels.

Throughout the survey process, the NORBIT equipment proved consistently reliable and flexible, with no system-related inconvenience throughout the program. Particularly during transit mapping, it often outperformed expectations in terms of scanning speed, operating at nominal survey and bottom detection capabilities up to 6.5 knots SoG in good sea/weather conditions. The sensor also turned out to show operational robustness in relatively rough sea conditions for long periods.

Drone mapping: activity completed – Polarquest 2021

After the last aerial survey over the Sallyhamna area in the afternoon of August 16th, Polarquest2021 UAV-based observation campaign has completed its activities. Preliminary data processing has started onboard S/Y Best Explorer as the boat is heading to its next leg at Ny-Ålesund scientific station. The drone mapping was specifically focused on expeditive geographical observations of relevant sites in Spitsbergen and Nordaustlandet, to provide information regarding different kinds of phenomena. Four sites were surveyed by GREAL/FTD tethered drone, yielding over 2000 images in the visible light (in Signehamna, Hansøya, Lågøya, Bockfjorden) and thermal infrared (Jotunkjeldene); a fifth survey was conducted by technical coordinator Michael Struik using a free-flying DJI Mavic mini drone over the Sallyhamna archaeological site. All surveys provided data for image-based modeling; final processing and analysis will take place at the European University of Rome (Italy) and the University of Gdansk (Poland) in the next months.  

The two missions over archaeological sites were conducted for geo-history-related scientific research purposes and to provide information regarding the current status of the areas for long-term monitoring. The flights over Hansøya and Lågøya were aimed to obtain sample-maps of the accumulation of driftwood and macroplastics on specific target sites of the shores of the two islands. Considering their different locations in the region, in particular their shore exposition, it is expected that the Hansøya flights will also provide valuable data about the geological character of the island and will produce a partial high-detail rendering of its topography.

The Bockfjorden flights allowed for a local mapping of two warm-water springs (~24°C) in the Jotunkjeldene area, associating visible-light images with thermal infrared frames, towards a more comprehensive description of this rare example of geothermal activity in Svalbard. The activity was a follow-up of a previous test-survey carried out during Polarquest2018. The survey was made possible by the use of a special drone configuration prepared by FlyToDiscover (Italy) upon GREAL’s specifications. High-detail, visible light and thermal infrared maps of the warm springs area will be prepared by Prof. Gianluca Casagrande at the European University of Rome and will be associated to a geological description of the area developed by Dr. Dominik Palgan (University of Gdansk).

FlyToDiscover for the third time in the Arctic with GREAL 

Yesterday UAV technical service provider FlyToDiscover delivered to GREAL, after the usual pre-departure preparations, the drone equipment that the laboratory will use during Polarquest2021, in the Arctic, these July and August.

The cooperation between the Italian company, based in Rome and led by Sandro Russello, and GREAL, has a long story and saw already joint work in the Arctic in 2018 (Svalbard) and 2020 (Greenland). The 2021 works plan draws from those previous experiences.

The drone prepared by FTD for use by GREAL is a customized version of the Phantom 4 Pro modified to effectively carry additional payload consisting in sensors. Furthermore, the drone can fly under tether in particular conditions, in order to prevent accidental fly-aways which can affect those machines in the specific research location. Although not designed for use in the Arctic, the popular drone proved an otherwise excellent survey machine in the workgroup’s previous research activities, provided that appropriate precautions are taken for its effective operation. 

The currently planned observation programme includes the collection of aerophotogrammetric data on some relevant sites as well as surveys with sensors for thermal and near infrared imagery.

GREAL returns to the Arctic with Polarquest2021

Two years after its first operational participation to a research activity in the Svalbard islands, and with the data from a second expedition in Greenland still under analysis, GREAL will be back to the Arctic in a few weeks. In the new programme, GREAL will be involved in expedition Polarquest2021, onboard S/Y Best Explorer under Arctic skipper Giovanni Acquarone.

Like in 2018, the project will be led by scientific communicator Paola Catapano (CERN, Geneva) head of a 9-people international workgroup including researchers, technicians and communication experts. Best Explorer is an Italian-built 51-foot sail-yacht that completely circumnavigated the Arctic Ocean between 2012 and 2019 and conducted scientific work on behalf of ENEA. She will depart her homebase in Tromsø, northern continental Norway, on July 15th, and will reach Longyearbyen, Svalbard Islands, on the 24th. After a brief stop-over, the quite dense research activity programmes will begin, along the western and northern coasts of the archipelago.

The main goals of the expedition include a sonar mapping of the seafloor (conducted by the University of Gdansk, the European University of Rome and NORBIT Subsea), off the coasts of Nordaustlandet, the second largest of the Svalbard islands, whose eastern shores are entirely covered with ice from the Austfonna glacier.

Other research programmes onboard will call for microbiological analysis led by the Swiss Polar Institute, detection of gas bubbles in the “water column” (University of Geneva and ISMAR-CNR), observation of the general environmental status and mapping of macroplastic litter in remote areas by the use of flying drones (European University of Rome, Italian Geographical Society, University of Gdansk).

The international crew who will take part in the expedition includes:

Giovanni “Nanni” Acquarone (skipper, expedition leader, Italy), Nicoletta Martini (co-skipper, Italy), Paola Catapano (project leader, scientific communicator, Italy), Michael Struik (technical coordinator, drone pilot, video/photographer, The Netherlands), Gianluca Casagrande (scientific coordinator, onboard scientist, Italy), Christel Hassler (onboard scientist, Switzerland), Kevin Monneron (diver, onboard scientist, France), Dominik Pałgan (onboard scientist, Poland), Elias Christoph Meier (student, Austria). The go-crew will be assisted by a shore-team coordinated by Best Explorer veteran, Italian sailor Salvatore Magri.

Best Explorer is expected to return to Longyearbyen by August 22nd. At that time, the laboratories in the expedition’s network will commence analysis of the expedition data, a process which will take several months. Meanwhile, as in 2018, images and footage from the expedition will be used to prepare documentary materials for public dissemination of the expedition and its scientific results.

Polarquest2021 will develop in some of the areas which saw, in 1928, the ordeal of airship ITALIA, disappeared with six crew-members during its return from the North Pole. During this summer activity, while scanning the sea-floor with a multibeam sonar provided by Norwegian manufacturer NORBIT Subsea, the crew will pay attention to the possible presence, in the area, of any trace that could be linked to the lost expedition.

Polarquest2021 continues the conceptual line developed by Polarquest2018 and NANUQ2020, developing research and communication about the Arctic with the use of “lightweight” and “low-environmental impact” solutions. The formula proved scientifically valuable in the past experiences and can effectively complement other more traditional research techniques.

“Custodians of the Memory” – First Webinar in “Shadow of Norge” project

The first international Webinar of the “Shadow of Norge” initiative was held on April 8th, opening the commemoration of the 95th anniversary of the Amundsen-Ellsworth-Nobile Transpolar Flight (1926).

The event was institutionally hosted by the Museo Umberto Nobile of Lauro, hometown to the Italian explorer and was chaired by the Museum’s director, Antonio Ventre.

The event was focused on family memories and historical places variously related to the 1926 expedition, e.g. the Oslo-Ekeberg stop-over place, the Ny-Ålesund advanced base in the Svalbard Islands, the historical life-places of the two leaders of the expedition, like Amundsen’s home in Uranienborg and places where Umberto Nobile lived, worked and paid visits in Rome, Lauro and Eboli.

Another theme explored by some of the speeches during the Webinar was the legacy left by the 1926 expedition, almost a century after its development, on both the education of future generations and the cultural relationships and bonds between Italy, Norway, and Russia.

The Webinar, whose programme can be downloaded here, was recorded and can be fully watched on the ShadowOfNorge youtube channel.

A virtual reconstruction of airship NORGE (1926-2021)

On April 10th, 1926, airship NORGE departed Rome, marking the beginning of the Amundsen-Ellsworth-Nobile expedition. A crucial voyage: for the first time in history a transpolar flight from Europe to America was achieved.  Waiting to celebrate the 95th anniversary of this expedition, GREAL Laboratory (, under the technical and graphic-design responsibility of dr. Roberta Rodelli and the scientific direction of prof. Gianluca Casagrande, brought the project “Shadow of NORGE” to life, in order to virtually retrace the famous journey.  The laboratory started working on the creation of a 3D model of the airship. The digital reconstruction is mostly based on original drawings by Umberto Nobile (designer and commander of NORGE), along with photos and films from that time. The general aim is to create a virtual copy, as much as possible similar to the real airship in appearance and dimensions.   The project is part of a series of activities and events that will celebrate the anniversary of this absolute first, with a little touch of magic obtained by the use of innovative technologies, possibly appealing to a wider audience.  Click here for the 3D model of the airship.

GREAL Seminar: Advanced tecniques for “image-based-modelling” virtualization of cultural heritage

The seminar will be given on December 7th 2020 by archaeologist Dr. Emiliano Tondi, a specialist in technologies for research and communication of cultural heritage.

The event will take place online through the Microsoft Teams channel of the Undergraduate program in Geography for Sustainable Tourism, and will include a methodological introduction and an excercise.

The seminar will be held in Italian language and is specifically offered to UER Students. 


The Polarquest2018 Arctic Expedition: An Open Access geographical report

Between July 22nd and September 4th 2018, an international Arctic research and communication expedition called «Polarquest2018» was conducted on board the eco-sustainable sail-yacht NANUQ .

The 17.8-meter sailboat cruised for a total of 3,564 nautical miles2 most of which north of the Arctic Circle (including two transfers and one operation leg). The crew, consisting generally of ten members, carried out a series of activities and observations in the framework of three research programmes.

The expedition was organized by Association Polarquest2018 (Switzerland) in partnership with Association Acapela and with scientific, technical and cultural entities from France, Switzerland, Italy and Norway3 . Funding was provided by institutional and private sponsors.

The project was highly interdisciplinary in nature. It consisted in navigating an experimental, environment-friendly floating laboratory through an Oceanic route, beyond the Arctic Circle and around Svalbard. During this travel, many activities involved scientific research, communication and storytelling.

This book is the third in the «Geografia a libero accesso» series, that the Italian Geographical Society has created to host its digital publications. The purpose of the editorial initiative is to make works by the Society’s members easier to access and circulate, so that results from studies and research activities may be freely disseminated. We hope that our fellows and the wide audience in the Web will appreciate this effort. Gianluca Casagrande’s book further extends the accessibility beyond the Italian-speaking context: a necessary choice, since it has an international endeavor as its topic and will have international readers as a significant share of its audience.

GREAL in Geneva for the scientific research mission NANUQ2020

Alessandro Prunesti, lecturer at the European University of Rome and GREAL’s deputy director, had a meeting yesterday in Geneva with Prof. Peter Gallinelli, director of the Passive Igloo Project and skipper of S/Y NANUQ, an innovative environmentally-sustainable research boat.

The purpose of Prunesti’s visit to Switzerland was to deliver scientific equipment put at disposal, by GREAL, to the NANUQ2020 Arctic expedition workgroup, lead by Gallinelli, for training and research this summer. The expedition is scheduled to depart in July, bound for Greenland, if mobility conditions in Europe, due to the developments of Covid19 pandemic, will allow. 

Aerial expeditive mapping and geographical observation in Svalbard by expedition Polarquest2018

The Polarquest2018 research and communication expedition circumnavigated the Svalbard Islands between August 4th and 24th, 2018. The expedition’s boat, an advanced Swiss-built experimental sailing laboratory called NANUQ served as an environmental friendly technological demonstrator which proved very effective in testing a complex programme of geographical observations in that remote Arctic archipelago.

One of the research sub-programs, called “AURORA” (Accessible UAVs for Research and Observation in Remote Areas) allowed to test methods and techniques for the geographical and environmental documentation of several places of interest in Svalbard. The approach followed during the work was to verify the effectiveness of citizen-science level equipment when tested for full-blown scientific applications.

The final results of the activity are being published and will be entirely issued during this incoming summer, suggesting a very high potential for a new possible profile in Arctic scientific research and dissemination of public awareness about the regions’assets as well as environmental issues.  


The conference will be held online on 21th of May, at 19.30 by Gianluca Casagrande, Associate Professor of Geography at Università Europea di Roma.

Call to International Conference – University of Roma Tre

Year 2019 marks two important anniversaries in the history of travels and explorations. It is indeed 500 years after Ferdinand Magellan’s departure for the first circumnavigation of Earth and 50 years after the first Lunar landing by Apollo 11.

Taking an opportunity from the commemoration of both events, the Italian Centre for Geo-Historical Studies and the “Giuseppe Caraci” geo-cartographic laboratory of the Humanities Department – Roma Tre University, along with the Escuela Española de Historia y Arqueología en Roma, is organizing an International Conference to be held in Rome. The event will be held on December 5-6, 2019, and it will focus on the importance of explorations and travels in pushing forward the evolution of thought and culture in science as well as in general perception, from politics to religion, from anthropology to history of art, from pharmacopoeia to food supply.


Artwork by: Daniel Eskridge –

The elements of innovation which pervaded Europe – and therefore the rest of the world – defined the beginning of a process involving differentiation, characterization, specification (even up to a terminological level) of quite many aspects of life. Such process was to continue in the following centuries, thanks to contacts with far civilizations, material and immaterial exchanges, reforms and revolutions which derived from the progressive widening of geographical horizons.

Regions of the Americas and Asia were subject to conquest, exploitation and evangelization, all affected by contrasts among European powers until the 19th century.

Travels to Americas and other unexplored regions (e.g. Australia and Africa), can be conceptually associated to those towards the Polar areas in the 20th century and to expeditions towards extra-terrestrial worlds. In the latter, the technological components seem to be predominant; however, they involve the same themes of perception, openness to novelty, in a continuous flow of travel experiences from the exploration of Earth to the exploration of outer space.

The Conference welcomes studies about travel and literature, evolution of scientific thought, geography and history, transcalar and long-term relations among Europe, extra-European continents and extraterrestrial spaces. Speakers from these fields are invited to present their reflections on the importance of travel in the opening of physical as well as mental spaces.

The due date for submitting proposals is September 15th, 2019. Applicants should send an e.mail to, specifying the title of the proposed work, the proponents’ names, a contact e.mail, the proponents’ affiliations, a short abstract (2000 characters max) and between 3 and 5 keywords.

S. Alessandrini (GREAL) gives a ‘Lectio Magistralis’ at the “XXXI National Conference of Aeronautical and Space Medicine”

The XXXI National Conference on Aeronautical and Space Medicine, organized by the Italian Association of Aeronautical and Space Medicine (AIMAS), took place in Vicenza from 19 to 21 June.

The conference, in addition to specific sessions for aero-medical examiners (AME), proposed a series of scientific communications on some major issues in aeronautical and operational clinical medicine, such as human factor and flight safety, space and physiology in extraordinary environments, forensic medicine and aeronautical work, proposal of guidelines for management in-flight diabetes.

The event was opened by a lectio magistralis by Dr. Sergio Alessandrini, a member of the Operational Committee of GREAL. Alessandrini is a forensic doctor and an expert on the history of Arctic exploration.


Dr. Sergio Alessandrini

The speech was on “The airship ITALIA expedition and the Red Tent – collective memory and historical“. Year 2019 marks the 91th anniversary of  such expedition, conducted in 1928 and directed by Gen. Umberto Nobile, of the Royal Italian Air Force.

The expedition followed the successful first transpolar flight performed by airship NORGE in 1926, and was intended as a full blown geographic exploration mission in the Arctic.

The ITALIA made three flights in the polar region and reached the North Pole on May 25th, 1928; however, it sadly crashed on the pack during its flight back towards homebase at Svalbard.

In the aftermath of the disaster, harsh controversies arose. Such polemics shook the prestige of involved Italian institutions and pushed the value of the whole expedition aside. On the long run, this marginalized the value of the ITALIA’s endeavor in both Italian and European collective memories, putting it, de facto, in oblivion.

The focus of Dr. Alessandrini’s speech was on current historical research which aims to highlight new evidence, emerging from archival data and primary sources. Such perspective, along with a new and more comprehensive reading of the traditional sources on the topic may contribute to a more effective understanding of the events and their historical dimension. It can also contribute to the memory of an expedition which consolidated, about a century ago already, Italy’s role as a major scientific and technical actor in the development of human presence and activity in the Arctic.  

Terres Film Festival: and the winner is…“Polarquest”

We gladly receive and relay news that the “Polarquest” documentary was awarded with the Sustainable Tourism and Ecology Prize at the Terres Film Festival.

GREAL’s participation to PolarQuest 2018 Arctic Expedition: Brief Report

Between July 21st and September 4th 2018, an international research and communication expedition called “PolarQuest 2018” was conducted on board the eco-sustainable vessel “NANUQ”. The 18-meter, 23-ton sailboat cruised for a total of about 3,500 nautical miles most of which north of the Arctic Circle. The crew, consisting generally of 10 members, carried out a series of activities and observations, as well as three scientific programmes directed by several Italian and international institutions. Among the former, there were the Italian Geographical Society and the Geographic Research and Application Laboratory (GREAL) og the European University of Rome. The trip and the activities onboard, whose results will be presented in several scientific publications, have been documented via the Web and social networks. TV documentaries about the expedition are currently being prepared in France and Italy. .

The expedition took place on the 90th anniversary of the arctic flights of the airship ITALIA (1928); commemorations and ceremonies took therefore place, in the presence and / or endorsement of a delegation of descendants of the airship’s crew.

The trip to PolarQuest 2018 began at the Icelandic port of Isafjörður on July 22nd. The boat reached Greenland and the Svalbard Islands. NANUQ arrived in the capital of the latter, Longyearbyen, on August 2nd. The second leg of the journey started from there on August 4th. After circumnavigating the two major islands of the archipelago, Spitsbergen and Nordaustlandet, NANUQ returned to Longyearbyen on August 24th. The last phase of the journey began on the evening of the 25th, as the boat departed Svalbard to cross the Barents Sea, bound to continental Norway. The expedition ended on September 4th, with the arrival in Tromsø. NANUQ was later moved to a smaller port for wintering.

During PolarQuest 2018, on August 13th, NANUQ, reaching the northernmost point of its navigation, navigated along a fringe of icefloe, not far from the extreme edge of the Arctic pack, in coordinates 82 ° 07’N, 25 ° 25’E. The point was less than 900 km from the North Pole. In that area, a sampling of microplastics and a measurement of cosmic rays were carried out. Both are probably the absolute maximums in latitude for the respective activities.

The boat Nanuq

NANUQ is a 17.8 m long sail-motor vessel with a displacement of 23 tons. It was designed by naval architect Peter Gallinelli, an expert in the construction of boats featuring high energy efficiency and low environmental impact. After a first sea trial in 2014, in 2015 NANUQ remained for 11 months – including the full wintering period – in Greenland. During the PolarQuest 2018 expedition, the boat carried out its 13th, 14th and 15th trips north of the Arctic Circle.

The vessel, which can easily reach and exceed 10 knots (18 km / h) on sail, is also equipped with a 85 Hp diesel engine. When the latter is used, the available range is about 2,000 nautical miles (3,700 km) at a cruising speed of 6.5 knots (12 km / h). NANUQ can accommodate up to a maximum of 12 people. It can support such crew with water, supplies and reserves ensuring, under normal conditions, complete self-sufficiency for about 30 days. The hull, made entirely of aluminum, is designed to sustain harsher environmental conditions than normally faced by boats of the same category and size.

NANUQ is a technological demonstrator of the innovative concept of boats with high environmental sustainability, intended to operate in the polar regions at any time of the year. A fundamental element of the project is the so called “Passive Igloo”, i.e. a set of technical features around which spaces inside the boat are made. NANUQ draws a significant part of its electricity from a wind generator and four photovoltaic panels. These sources are useful to reduce the need for using a traditional generator. The walls, the portholes and the interiors are made of, or insulated with, high energy-efficient materials. They are able to store heat from the crew bodies and from various devices on board (systems, computers, kitchen, etc …).

The scientific activity programs

NANUQ, classifiable as a “technological demonstrator” of new eco-friendly solutions for naval constructions, has been configured as a sustainable research vessel for the PolarQuest 2018 expedition. The boat was therefore equipped as a laboratory for carrying out various observation and research task. A specific nature of the program for the entire expedition was the extensive use high accessibility technologies. They were specifically selected to be low-cost and, as far as possible, comparable to those available to citizens’ science applications.

On board – and on land during various stages of the journey – work was carried out related to the following three research programs:


The activity has been coordinated by the Enrico Fermi Centre as part of the collaboration Extreme Energy Events with the support of researchers from the National Institute for Nuclear Physics, the University of Bari, the University of Bologna and the Polytechnic University of Turin. The final assembly of the device has been carried out at CERN in Geneva. The three “E” in the name refer to an INFN multi-year research and education program called “Extreme Energy Events”. The activity consisted in measurements and recording of cosmic rays at high latitudes by use of an innovative detector. The instrument was built specifically for installation on NANUQ. It therefore featured smaller dimensions and power consumption, in comparison to standard devices. Moreover, the hardware of the detector was custom-built with the use of low-cost components. The final assembly of the machine was conducted at CERN by Italian, Swiss and Norwegian high school students. The on board leading scientist for the PolarQuEEEst program was Dr. Ombretta Pinazza (INFN and CERN). Data recordings took place almost constantly during the entire navigation from Isafjörður to Tromsø.

Thanks partially to a series of previous experiences – in other areas and previous times – by NANUQ, a floating microplastic sampling programme was carried out, both during the first leg of NANUQ’s voyage (Iceland-Greenland-Svalbard), and during the second (circumnavigation of Svalbard). The project was directed by the Institute of Marine Sciences of the CNR (ISMAR) under the supervision of Dr. Stefano Aliani. The observations on board of NANUQ were carried out by two young operators, environmental activist Safiria Buono (age 19, Italy) and co-skipper Mathilde Gallinelli Gonzalez (age 22, Switzerland).

The samples are then preserved and transferred for laboratory analysis to allow for the study of the distribution and characteristics of this form of pollution (image: Gianluca Casagrande).

3-AURORA (Direction: Italian Geographical Society and GREAL – European University of Rome)

The project (whose name stands for Accessible UAVs for Research and Observation in Remote Areas) consisted of a proof-of-concept of observations and geographical documentation in Arctic environments, conducted by low-cost drones, sensors and consumer-level software. Tests were carried out in different places, where specific survey and observation profiles could be tested. These spanned from qualitative observation and aerophotogrammetry, expeditive cartography, observations of landscapes in the thermal and near infrared. Attention was also paid to verifying the effectiveness of the equipment in documenting and story-telling Arctic environments. This was considered to be relevant in a region like Svalbard, currently in transition from being an anaecumenic context into being a space increasingly subject to settlement, usage and tourism. The person in charge of the project was geographer Prof. Gianluca Casagrande.

NANUQ’s crew during the second leg of the journey: Circumnavigation of Spitsbergen and Nordaustlandet

The main phase of the PolarQuest 2018 expedition took place during the second leg. It included a circumnavigation of the largest Svalbard islands, namely Spitsbergen and Nordaustlandet. NANUQ left the port of Longyearbyen on August 4th and returned there on the 24th, after a 1,500 nautical mile journey. Stops were made in various locations and a memorial navigation was also carried out, to honor the 90th anniversary of airship ITALIA expedition. Such navigation took place in the open sea, north-east of the archipelago. It was later extended northbound, up to the external edge of pack. During this phase of PolarQuest 2018, there was a permanent crew of 10 people on board: 4 were mainly in charge of navigation and onboard operations; 6 were prevailingly involved in scientific and communication activities. On particular occasions for brief time, passengers were also admitted on board.

Route and activities around Svalbard

The second part of NANUQ’journey included stops in places of interest, essentially along the Longyearbyen – Ny Ålesund – Nordaustlandet – Austfonna – Freemansundet – Hornsund – Pyramiden -Longyearbyen route. At the northeastern edge of Nordaustlandet NANUQ interrupted the coastal navigation and took to the open sea for a historical-commemorative navigation to remember the expedition of airship ITALIA. On August 13th she reached a position in the immediate vicinity of the point from which the first SOS of the shipwreck survivors was launched on 26/5/1928 (81 ° 14’N, 25 ° 25’E). There, on behalf of a delegation of descendants of the airship’s crew, a brief ceremony was held in memory of the missing aeronauts. Represented institutions were the Italian Geographical Society (ITALIA’s operator at the time of its 1928 polar expedition), the Italian Air Force, the Italian Navy, as well as the Associazione Nazionale Marinai d’Italia. NANUQ then headed north, reaching an area at the extreme edge of the pack (82 ° 07’N, 25 ° 25’E).

During the whole trip, activities related to research and communication programs on board were carried out.

In the following pages, a series of images and brief descriptions summarize the work on board NANUQ, with particular reference to the AURORA project.

Visit to NY ÅLESUND (Kings Bay) and ceremony with a delegation of descendants of ITALIA’s crew

The first stop-over of the expedition took place at Kings Bay, the old base for both the NORGE (1926) and ITALIA (1928) polar airships. The mooring pylon for the blimps is still preserved as a monument. Nearby, it is possible to see remainings of the wooden hangar that was designed by Italian engineer Felice Trojani and built by Norwegian craftsmen. Kings Bay, with the small settlement of Ny Ålesund is today home to an important international scientific settlement (image Gianluca Casagrande).

Expeditive aerophotogrammetric survey of Virgohamna, Danes Island (DANSKØYA)


Screenshot taken from a drone approaching Virgohamna beach (Danskøya). The place was the departure site for Andrée’s (1897) and Wellman’s (1906, 1907 and 1909) polar expeditions. Formerly a popular landmark for tourism, Virgohamna is now heavily protected and access to it is regulated. An expeditive aerial reconnaissance about the current state of the site was carried out by launching two drones from NANUQ. The boat was anchored a safe distance from the beach (image: Gianluca Casagrande).

Virgohamna in 1906 at the time of the first Wellman expedition. On the left of the photo is the hangar of airship AMERICA. On the right, in the foreground, remains of installations of the Andrée expedition, dating back to nine years earlier. At the time when the photo was taken, Andrée and his two companions Fraenkel and Strindberg were reported missing in an attempt to reach the North Pole aboard balloon Örnen. Their bodies, documents and photos from their tragic expedition were unexpectedly discovered on Kvitøya (the “White Island”), eastern Svalbard, in 1930. (Image: North Pole Expedition Museum, Longyearbyen).

Trollsprings, Bockfjorden.


Aerial picture of the valley at the southern limit of Bockfjorden. The site was visited on August 9th by a PolarQuest 2018 survey group. The reason for interest towards this site was the presence of residual hydrothermal activity. The area, also defined by the toponym of “Trollsprings” is visible in the picture and corresponds to both sides of the evident strip of vegetation at the bottom of the image. On that site there are pools of water at a constant temperature of approximately 20 ° C (image: Michael Struik).

Pair of images in visible light (left) and thermal infrared (right, rotated). The acquired data demonstrated the overall capability of a small thermographic sensor to identify the presence of hotspots in the ground all around the hydrothermal sources (images by Michael Struik and Gianluca Casagrande).

In this site a research group of the CNR had left, in 2008, some probes for carrying out environmental measures. Since a planned later expedition was cancelled, it was no longer possible to recover the sensors and logged data stored with them. The PolarQuest 2018 survey group was therefore requested to retrieve the probes if possible. The staff, however, gave up the attempt after finding that in the points indicated as positions for the instruments, a natural ecosystem appeared to be abundantly developed. (photo and processing: Gianluca Casagrande).

August 11th

Kapp Rubin and Nord-Kapp – Identification attempt of historical cairns

A series of drone flights was performed at both Kapp Rubin and Nord-Kapp in the attempt of spotting historical “cairns” (small stacks of stones) associated to the Albertini expeditions (1928-1929) in both areas. Two cairns were video-recorded on the top of Nord-Kapp. In the area between Nord-Kapp, Kapp Rubin and Kapp Platten, the research group carried out extensive surveys by on-foot search, observation of the shores from a dinghy, and by aerial view by drones. Although the identification attempt did not provide conclusive results, the validity of the working method was easily ascertained. Among other things, it was possible to verify the particular effectiveness of the drone for this type of archaeological reconnaissance. (image: Gianluca Casagrande).

Survey of Alpini Island (ALPINIØYA)

The “Isola degli Alpini” was officially discovered in summer 1928 by Italian Royal Army officer Gennaro Sora, of the Alpine Corps. He and fellow Arctic explorer Sief van Dongen were travelling through northern Svalbard in search for the survivors of airship ITALIA. Alpiniøya is a small rock formation. Although it is completely depopulated and visited very rarely, the island appeared cluttered with plastic debris and waste. The latter was present in considerable quantity and, for the most part, it could be interpreted as deriving from fishing activities. This form of pollution has been observed by PolarQuest 2018 in a large majority of the land area visited during the expedition north and east of Svalbard.


After ferrying some crewmembers top the shore, Michael Struik restarts the dinghy, leaving for NANUQ -visible in the background- to pick up a second group (image: Gianluca Casagrande).

36-weapons-polarquest-2018Safiria Buono monitors for polar bears around the group of observers on Alpiniøya beach. In addition to the large-caliber rifle, the observers had flares and maintained radio contact with NANUQ. According to Svalbard regulation, all persons accessing depopulated areas must have at least one armed escort, trained to deal with possible – albeit very rare – attacks by bears. A few days before NANUQ moved to north Svalbard, a polar bear had been shot in the same area. It had attacked a group of tourists, just landed from cruise ship Bremen. During the PolarQuest 2018 expedition, the crew spotted a total of 7 bears (one lurking on a beach on the island of Storøya, later on August 14th). Nevertheless, the crew never faced any contact with polar bears which might have required self defense with weapons (image: Gianluca Casagrande).

Navigation along eastern and southern fronts of Austfonna glacier.


August 16th. Michael Struik and Alwin Courcy during their navigation watch on NANUQ. Among the duties of all crew members, without distinction – except during short journeys or anchor periods – there were 2-hour surveillance shifts. Each shift was followed by 7 hours free for other jobs or rest. These 9-hour cycles, along with continuous presence of daylight, contributed to disrupt perception of time and sleep-wake cycles in the less experienced crewmembers (image: Gianluca Casagrande).

Expeditive aerophotogrammetry of Inglefieldbreen glacier

One of the PolarQuest 2018 objectives was to reach Inglefieldbukta to make an observation of Inglefieldbreen glacier. This glacier had previously been subject to periodic monitoring by the working group of the scientific observation boat “Vagabond”. The “Vagabond” team, once informed about PolarQuest 2018, had explicitly requested a visit to the glacier. In this context, a georeferenced expeditive aerophotogrammetry of the glacier front was taken by drone, for an extent of about 3 kilometers.

August 23rd

Visit to Pyramiden

Pyramiden was a Soviet (now Russian) mining city, founded in 1927. It was established to extract coal from mines in the mountain nearby, featuring a typical natural “pyramid” at the top. The city was run and is currently owned by mining company Arktikugol. It was shut down and abandoned in 1998. Most of the buildings and structures are now under official protection; surveillance and maintenance services are now active all-year round. After having being a ghost settlement for decades, Pyramiden appears to be increasingly qualifying as a historical landmark and a tourism asset. During the summer season the site, where a hotel has been fully reactivated – is a typical destination of frequent guided tours. The PolarQuest 2018 group visited the site with specific interest in the structures that are still completely abandoned. Among these, there is an industrial warehouse and the complex system of the funicular that climbed from the city in the valley up to the mine entrances higher on the mountain slopes. The visit in those sites evidenced an ongoing state of considerable deterioration and the presence of potential hazards (asbestos, residues of mining activities). Such conditions should be promptly addressed, if wider tourist access to Pyramiden is planned.

GREAL in the Arctic with PolarQuest 2018

The Geographic Research and Application Laboratory of the European University of Rome will participate in the PolarQuest 2018 expedition to the Arctic region with a geographic observation program by drones. PolarQuest 2018 is currently in an advanced state of preparation. It aims to conjugating scientific research and communication on several relevant phenomena involving the Arctic environment.

The activity program calls for a scientific cruise onboard experimental sailboat NANUQ. The 60-foot vessel was designed by the Swiss architect and scientist Peter Gallinelli around passive-architecture criteria.

This designing approach allows to operate in high energetic efficiency conditions with limited environmental impact.

NANUQ is currently being turned into a sailing scientific laboratory. Three research programs are scheduled to be coordinated onboard, respectively by  the Centro Fermi, by the Institute for Marine Sciences of Italian National Research Council (ISMAR-CNR) an by GREAL.

The first program calls for the installation onboard NANUQ of a cosmic ray detector to be operated at high latitude and will be carry out with the support of researchers from INFM, University of Bari, University of Bologna and the Polytechnic of Turin, falling under the activity “Extreme Energy Events”. The second one will perform water sampling in order to research on the nature and distribution of macro/micro plastics in the region North of Svalbard by the deployment of a tool called “MANTANET”.

The third program, directed by GREAL, is called AURORA (Accessible UAVs for Research and Observation in Remote Areas) and will consist in a series of survey and/or observation flights over some coastal environments by the use of mini and micro-drones.

The rationale of this specific activity is to provide methodological indications in order to apply these new accessible and powerful technology to scientific research and cultural communication about Arctic environments.

NANUQ will depart on July 21st from Iceland and will reach Svalbard (an archipelago within the Arctic Circle) for a technical stopover in early August. On August 4th, the vessel will leave the port of Longyearbyen and will attempt the circumnavigation of the islands, with a brief call to the scientific base of Ny Aalesund and several observation landings on the northern shores of Nordaustlandet. In the second half of August, if the ice conditions will allow, NANUQ will move towards the North, in the open sea, for a visit in the area were the exploration airship ITALIA was lost in 1928.

After a further stop in Longyearbyen the boat will depart again on August 25th towards Tromsø, in Norway, final destination of her journey

During the expedition, NANUQ’s international crew will constantly include 10 members (with turnovers along the route), 4 in charge of the navigation and 6 in charge of research and communication activities.


Initial tests for the ENVI-PHANTOM

GREAL/FTD ENVI-PHANTOM is an activity program based on the use of several system configurations for DJI Phantom quadcopter aimed to performing optimized geographic observation.

The program is developed by GREAL in cooperation with FlyToDiscover and will call for several application activities during 2018.

Given the modularity of configurations, the experimental activities have so far considered several versions of the popular DJI drone: Phantom 2, Phantom 3 and Phantom 4 Pro.

The advantage of using this particular type of machine is typically due to its modest dimensions, good endurance and significant technical reliability.

At present, several combinations of sensors, sensor mounts and RPA platforms. The purposes of the ENVI-Phantom will include definition and scientific validation of optimized geographic observation techniques relying on low-cost hardware and software.

Among the first activities planned for the operational tests, there is the geographic observation series proposed by GREAL within the framework of the PolarQuest 2018 Arctic expedition ( 

The TimeFlyers workgroup involved in precision aerophotogrammetry within the Colosseum, Rome

Between October 17th and 20th the TimeFlyers workgroup was involved in archaeological aerophotogrammetry operations by the use of microdrones within the Anphiteatrum Flavium (Colosseum) in Rome.

The main activity profile consisted in photogrammetric passes and video/photo documentation in the areas of the so-called hypogean level, i.e. the structural complex which was originally under the arena and is now partially exposed due to collapse of original ceilings.  

The primary goal of the work was to obtain a large scale (1:50) ortophoto so as to document the current status of ancient structures. As a side-activity to this type of documentation, a collection of still images and video footage was acquired for additional information.

One of the innovative aspects of the operation was the use of micro-drones of the “0.3 kg” category. Such class of UAVs is regulated in Italy by the article 12 section 5 of the ENAC Regulation on Remotely Piloted Aerial Systems, and calls for UAVs to be within 0.3 Kgs of take-off mass, not faster than 60 kmph and fitted with shielding for the propellers. Under these conditions, registered and insured UAVs can be legally flown in urban settings and without the need of a specific license for the pilot, both elements being subject to heavier requirements for larger drones.

In the specific case, deployed UAVs were FTD Sparks, one of the Italian custom variants of the widespread DJI Spark quadcopter.

Two drones were flown at a-time (led by two separate teams) and they were used to survey several different kinds of structures both in outdoor and indoor environments, aiming to a comprehensive and accurate documentation of the overall space.

The Technical director of the operation was archaeologist Emiliano Tondi (Poleis S.C. a r.l.); GREAL was represented by Prof. Gianluca Casagrande and Mr. Filippo Fiorentini. UAV technical consultant was Mr. Sandro Russello (FlyToDiscover)

GREAL at GISDay 2017, CIRGEO, University of Padua

GisDay 2017, organized by CIRGEO, Padua University under Prof. Massimo De Marchi’s direction, was held today at the historic “Sala dell’Emiciclo” in Padua’s Botanic Garden. Quite a wide series of brief reports was presented by scholars and professionals on subjects related to Geographic Information Science (GIS) and drones (RPAS).

The event is part of the activities of the Post-graduate certification program in Geographic Information Systems and Remotely Piloted Aircraft Systems, now in its third edition. GREAL was represented by Prof. Gianluca Casagrande, who gave a 15 min speech on “Micro-drones under 0.3 kgs of mass and documentation of Cultural Heritage.

Considerations on an innovative tool”. Based on recent research experiences gathered by GREAL in its cooperation with FlyToDiscover srls and Poleis SCarl, the talk was focused on perspectives and issues in the use of very small drones, a category of RPAS which is currently cleared to operate in Italy, according to present regulation, with special opportunities.

First flight-session FTD Spark NIR “testbed” drone

Sandro Russello, head of FlyToDiscover, took the FTD Spark NIR “testbed” drone into the air today. This is the first series of experimental flights for this 340 g quadcopter, fitted with an additional near-infrared (NIR) camera.

The prototype will undergo a series of validation tests for survey purposes and will serve as a testbed towards the development of a lightweight, low cost commercial survey RPAS. The FTD Spark NIR is the outcome of a close partnership and collaboration between FTD and GREAL towards the development of an accessible survey tool for scientific and professional applications. Such kind of cooperation between the two partners is not new, as it led in the past to the implementation of other prototypes, most notably the FTD 160X4 .

From the standpoint of geographic research, the implementation of Spark NIR is in line with the traditional GREAL’s approach to develop high-accessibility tools for practical applications. In particular, this project aims to take advantage of the regulatory and practical opportunities provided by minimal-sized drones for studies on vegetation, especially in urban and densely populated contexts.


GREAL representatives at the International Eugeo 2015 Congress

The 2015 edition of the Eugeo International congress was held in Budapest from August 31st to September 2nd. The European University of Rome and GREAL were represented there by Prof. Gianluca Casagrande and Mr. Alessandro Prunesti, who gave presentations in two separate sessions, on “The Benefit of Remote Sensing in Geography” and “The future of cities between competitiveness and vulnerability: the smart city perspective“ respectively.
The former session was organized by a group of Hungarian researchers in order to discuss innovative applications of Remote Sensing to Physical and Human Geography. The latter, proposed by a group of Italian scholars and experts, was an extensive overview of innovative perspectives on the world of Smart Cities.
