Reliable access to Arctic research infrastructure is critical to the future of polar science. In cultivating proposals, it is essential that researchers have a deep understanding of existing platforms when selecting the appropriate research site and experimental design for projects. However, Arctic infrastructure platforms are often funded as national assets, and choices for what would be the best platform for the project are sometimes at odds with a researcher’s ability to gain access. Researchers from Arctic and non-Arctic nations are poised to benefit from reducing barriers and increasing cooperation around transnational access to Arctic infrastructure, allowing scientists to successfully execute the research that is most needed rather than what is just logistically feasible. This commentary provides a summary of findings from a workshop held at the 2021 Arctic Science Summit Week to discuss navigating “transnational” or “cross-border” access to national research infrastructure. This workshop brought together users and operators of Arctic infrastructure platforms with the three goals of identifying challenges, best practices, and possible next steps for improved collaboration.

Svalbard’s geographical positioning, environmental characteristics and multinational population make it conducive for considering informality and multinational cooperation in disaster risk reduction and response. Most research examining disaster risks and disasters for Svalbard has focused on Norwegian efforts in and for the main settlement of Longyearbyen, with none covering Svalbard’s second-largest settlement of Barentsburg. This paper addresses this gap by analysing how 21 Barentsburg residents deal with disasters. We conducted semi-structured interviews, visually aided by the revised PRISM (Pictorial Representation of Illness and Self Measure) tool, to examine interviewees’ disaster perceptions, sources for disaster-related information and learning, and formal and informal sources for dealing with disaster risks and disasters. Our findings suggest that, despite being risk-aware, Barentsburg interviewees consider the settlement, and Svalbard as a whole, to be safe. The explanation is their faith in the existing disaster-related mechanisms, made up of both local Russian entities and the Norwegian rescue services, especially Svalbard’s governor (Sysselmesteren). Interviewees rely significantly on Russian and Norwegian informal actors and relationships for disaster-related information. These findings suggest that alongside formal approaches, informality may play a significant role in dealing with disasters in Barentsburg, which itself might serve as a platform for international cooperation.

In 1953–55 the Canadian government experimentally relocated Inuit (Eskimo) families from the region of Port Harrison (Inukjuak), on Quebec's Ungava peninsula, to Ellesmere and Cornwallis Islands in the Arctic Archipelago. Today Inuit relocatees allege that they were deceived by the government and suffered greatly as a result of the experiment. The government asserts that the relocation was undertaken for humanitarian reasons. The controversy has recently resulted in hearings before a Canadian parliamentary committee on aboriginal affairs and the Human Rights Commission. A study of the relocation issue prepared for the government, known as the ‘Hickling Report’, rejects Inuit claims of mistreatment. In this paper the Hickling report's findings are assessed. Contrary to the report's conclusions, documentation suggests that one of the government's motives for undertaking the relocation pertained to Canadian sovereignty and exercising ‘effective occupation’ of the islands.

In summer 1911—1912, during Robert Falcon Scott's Terra Nova expedition (1910–1913) a field party of four men led by the geologist Griffith Taylor surveyed the coast and hinterland of Victoria Land, Antarctica. During their stay at Cape Geology (77°00'S, 162°35'E), Granite Harbour, the members of the ‘western geological party’ built Granite House, a rock shelter used as a kitchen. The field party finished its work in the Granite Harbour region in the second week of January 1912, but heavy sea ice prevented Terra Nova from reaching the prearranged meeting point at the entrance to the bay. Faced with the possibility of being trapped for the winter, the party left Granite Harbour and travelled overland back toward the winter quarters on Ross Island. One month later the party was picked up by Terra Nova and was returned safely to Cape Evans. During an expedition to Granite Harbour in January-February 1992, the authors discovered an 80-year-old note left by the field party in a cigarette tin in the vicinity of Granite House. Dated 14 January 1912, the note was written by Taylor to Lieutenant H.L.L. Pennell, the skipper of Terra Nova, to let him know that the party had left for Cape Roberts. Granite House is a significant relic of the ‘heroic era’ and merits protection.

The 12th century Norwegian text Konungs Skuggsjá (King's Mirror), a didactic work prepared by one or several authors, probably for the education of a king's sons, provides some of the earliest known descriptions of sea-creatures (legendary and real) inhabiting northern Atlantic waters. Most of the descriptions give sufficient detail to allow identification with species common in the area today. This article (the second of two articles on Konungs Skuggsjá; see Polar Record, (1985), 23(141): 615–27), presents translated sections of the original text, and possible identifications of 26 species with discussion, notes and comments.

Karl Ernst von Baer coined the word ‘Eiskeller’ (ice-cellar) to describe the Kara Sea in 1837, but he did not define precisely what he meant. The word was seized upon by subsequent geographers, notably Friedrich B. Lütke and August Petermann, as implying that the sea was unnavigable. However, when numerous successful voyages — by Norwegian fishermen, Joseph Wiggins, and Adolf Erik Nordenskiöld — showed that this was not the case, it was Baer, and not Lütke or Petermann, who was criticised for the claim. Baer only defended himself against these allegations in 1876, the year of his death, 39 years after he had first used the term.

Systematic image-classification methods were applied to ALMAZ, ERS-1, and JERS-1 synthetic aperture radar (SAR) and Landsat-TM multispectral satellite images to evaluate the relative information content of the satellite data for discriminating wet tundra habitats in northern Alaska. Results suggest that SAR data can be used to concurrently detect a maximum of four or five landcover classes using the methods of this study. Combining two or more SAR images from different satellites improved the detection of some classes, particularly water bodies. Combining full-resolution SAR data with Landsat-TM did not improve the detection capabilities of Landsat-TM alone. Further research is needed to assess other image-classification and SAR data processing methods.

Early in 1945 a rumour was spreading round that a film was to be made of Scott's Last Expedition, and the reaction among the “survivors”—as the press chooses to call us—was interesting. It was, almost universally, one of dismay and even antagonism. The arguments against it were varied. The story was already sufficiently told; it was out-of-date; to film it would be an invasion of privacy, and so on and so forth.

Seabird populations in Antarctica serve as indicators to assess the impacts of global environmental change. Ecological data on seabirds in Antarctica are scarce due to limited knowledge on their distribution and abundance in most parts of the continent. In this study, we investigated the status of seabird species around the Indian research stations Bharati at Larsemann Hills, Prydz bay and Maitri at Schirmacher Oasis, central Dronning Maud Land located in east Antarctica. We conducted primary surveys during austral summers under the Indian Antarctic Program and compiled published as well as unpublished information on seabird distribution from these areas. We employed intensive area search methods to locate presence of seabird nesting and moulting sites. Ten species were recorded from Larsemann Hills with confirmed breeding of snow petrel, south polar skua and Wilson’s storm-petrel. Only south polar skua and Adélie penguin were reported breeding at Schirmacher Oasis with unconfirmed breeding of Wilson’s storm-petrel. This study presents the first detailed synthesis of status of seabirds from Larsemann Hills and Schirmacher Oasis regions in Antarctica and serves as a strong baseline for future ecological work on seabirds in the sector of operation of Indian Antarctic Program.

Joseph Elzéar Bernier's well known sector claim of 1 July 1909 was predated by a similar, but until now unknown, proclamation in 1907. Prime Minister Sir Wilfrid Laurier, although eager to assert Canadian sovereignty, was unwilling to countenance the first claim because he did not think that the right time for such a gesture had yet come. However, in 1909 Bernier's action was welcomed, but only as a convenient way to counter the widely publicised American claim made by Robert Peary. In the eyes of government officials, neither of Bernier's proclamations held any real importance for Canada's northern sovereignty which rested primarily on the 1880 transfer of ownership from Britain. Bernier believed that his achievements had never been sufficiently recognised, but in fact the problem was that he himself overrated their significance.

On 21 July 1904, just over 80 years ago, the barque-rigged, Norwegian-built auxiliary steamship Scotia sailed home up the Clyde with members of the Scottish National Antarctic Expedition (SNAE), concluding one of the most successful expeditions of the heroic period of Antarctic exploration. Contemporaneous with the more spectacular British Antarctic Expedition (1901–03) commanded by Robert Falcon Scott, the Scotia party under William Spiers Bruce had overwintered on Laurie Island (60° 44ʹ S, 44° 50ʹ W) in the South Orkney Islands, explored for the first time the oceanography of the Weddell Sea, assembled an important collection of scientific material, and discovered Coats Land, an icebound stretch of the East Antarctica coast.

While Scott's Discovery expedition had emphasized geographical exploration inland from the Ross Sea sector of Antarctica, Bruce in the Scotia had concentrated more on scientific discovery in the Weddell Sea sector. On 12 November 1904 in Edinburgh, members of the Scotia and Discovery expeditions were guests at the 20th anniversary dinner of the Royal Scottish Geographical Society, Bruce and Scott together responding to a presidential toast that honoured the success of both.

The distribution, density and percentage contribution of pack ice seals during ship-board censuses in the marginal sea ice zone beyond the Lazarev Sea in spring 2019 are presented. Adult/juvenile crabeater seals (n = 19), leopard seals (n = 3) and Ross seals (n = 10) were sighted during 582.2 nm of censuses along the ship’s track line in the area bounded by 00°00’–22°E and 56°–60°S. Antarctic fur seals (n = 21) were only encountered on the outer fringes of the pack ice, and Weddell seals were absent due to their primary use of fast ice and inner pack ice habitats close to the coast. Crabeater seal sightings included juveniles (n = 2) and another four groups of 2–3 unclassified crabeater seals, singletons (n = 5), single mothers with pups (n = 3) and a family group (n = 1 triad). Only one leopard seal attended a pup, while no Ross seal pups were located. The survey was likely of insufficient effort, in both extent (north of 60°S) and duration (18 days), to locate seals in considerable numbers this early (late October/early November) in their austral spring breeding season.

Project MIZPAC (Marginal Ice Zone Pacific) was initiated in 1971 by the Arctic Submarine Laboratory, San Diego, California, to further the US Navy's understanding of problems associated with operating submarines under ice-covered oceans. Oceanographers from the Naval Postgraduate School took part in six summer cruises to the marginal sea ice zone (MIZ) of the shallow Chukchi Sea between 1971 and 1978 (Fig 1), providing the first detailed observations of the temperature-salinity structure within this dynamically active zone. Strong horizontal gradients of temperature and salinity marking boundaries between water masses (fronts), are widespread and well developed (Paquette and Bourke 1981). Where water masses intrude upon each other large-scale temperature inversions (anomalous increases in temperature with depth) often appear. Termed fine structure, these temperature anomalies include some of the largest observed anywhere in the world's oceans, sometimes exceeding 2°C over vertical distances of 5–10 m (Paquette and Bourke 1979). This article describes some of the fronts and fine structures observed in the Chukchi Sea, and shows how they develop within the general patterns of sea ice and circulation.

Temporally and spatially increasing information on the distribution of Adélie penguin (Pygoscelis adeliae) breeding sites is used as an index of various national activities in eastern Prydz Bay, East Antarctica. Recorded instances of such sites are used to indicate both exploration and enhanced local knowledge. While Norwegians discovered the area (1935), and revisited it (1937), reports of penguins were minimal. The 1938 Ellsworth expedition added few details and the potential of Operation Highjump (1947) photographs to delimit breeding sites was never realised. Observations by Australian expeditioners from the mid-1950s onwards, supplemented to some extent by those from the Soviet Union, increased information substantially. When Davis station was established (January 1957), at least five breeding sites were known around eastern Prydz Bay. By 1973 this had increased to 23 or 24 sites, mostly north of the Sørsdal Glacier, which had apparently acted as a barrier to land-based exploration. Data available to 1980 showed 20 sites in the Vestfold Hills, added two in the Rauer Group, and omitted some recorded earlier. Ground surveys of the Vestfold Hills (November 1973) increased known sites slightly, discounted erroneous records, and massively increased numbers of individual colonies. In 1981 an air survey recognised 24 sites in the Vestfold Hills and increased those known to 47. In approximately the same period, official Soviet records showed perhaps four sites in the Vestfold Hills and another in the Rauer Group. Early reports provided poor estimates of breeding population sizes — totals of some 130,000 (or 174,200) pairs in the Vestfold Hills in 1973 are compared with perhaps 196,600 in 1981, with another 129,000 pairs to the south. By 1983 locations of breeding sites in the Vestfold Hills were well established, and this was achieved in southern Prydz Bay following publication of 1981 survey results.

Progression of information regarding breeding sites in eastern Prydz Bay was slow. Initial Australian activities were slight following acceptance of its Antarctic Territory (1933). However, a Soviet Antarctic whaling fleet, uncertainty regarding American and Soviet intentions, and the imminent International Geophysical Year increased Australian interest. A station was established, local search areas expanded, and enhanced details regarding penguin breeding sites and colonies followed. Data reviews and surveys followed increasing international interest in southern ecosystems. Improved knowledge regarding the species' local populations reflected changing political agendas. Indeed, ‘knowledge’ itself gave early support to territorial claims. Participation in international surveys became an acceptable scientific endeavour, anticipated under Treaty agreements and promoted by associated organisations. In such fora, surveys and monitoring are expected, although not necessarily furthering the strength of existing claims.

In the present era of instantaneous telecommunications it is scarcely conceivable that two major exploring or scientific expeditions could be planning simultaneously to operate in a particular area of the Arctic (or indeed anywhere on earth) in complete ignorance of each other's intentions until each arrived in the field. At the turn of the century, however, this was indeed possible, and did in fact happen in the case of a little-known expedition to Ellesmere Island, led by Dr Robert Stein, which found itself completely eclipsed by the much better equipped and funded expedition of Otto Sverdrup in Fram.

The German Antarctic Receiving Station (GARS) O’Higgins at the northern tip of the Antarctic Peninsula is a dual purpose facility for earth observation and has existed for more than 20 years. It serves as a satellite ground station for payload data downlink and telecommanding of remote sensing satellites as well as a geodetic observatory for global reference systems and global change. Both applications use the same 9 m diameter radio antenna. Major outcomes of this usage are summarised in this paper.

The satellite ground station O’Higgins (OHG) is part of the global ground station network of the German Remote Sensing Data Centre (DFD) operated by the German Aerospace Centre (DLR). It was established in 1991 to provide remote sensing data downlink support within the missions of the European Remote Sensing Satellites ERS-1 and ERS-2. These missions provided valuable insights into the changes of the Antarctic ice shield. Especially after the failure of the on-board data recorder, OHG became an essential downlink station for ERS-2 real-time data transmission. Since 2010, OHG is manned during the entire year, specifically to support the TanDEM-X mission. OHG is a main dump station for payload data, monitoring and telecommanding of the German TerraSAR-X and TanDEM-X satellites.

For space geodesy and astrometry the radio antenna O’Higgins significantly improves coverage over the southern hemisphere and plays an essential role within the global Very Long Baseline Interferometry (VLBI) network. In particular the determination of the Earth Orientation Parameters (EOP) and the sky coverage of the International Celestial Reference Frame (ICRF) benefit from the location at a high southern latitude. Further, the resolution of VLBI images of active galactic nuclei (AGN), cosmic radio sources defining the ICRF, improves significantly when O’Higgins is included in the network. The various geodetic instrumentation and the long time series at O’Higgins allow a reliable determination of crustal motions. VLBI station velocities, continuous GNSS measurements and campaign-wise absolute gravity measurements consistently document a vertical rate of about 5 mm/a. This crustal uplift is interpreted as an elastic rebound due to ice loss as a consequence of the ice shelf disintegration in the Prince Gustav Channel in the late 1990s.

The outstanding location on the Antarctic continent and its year-around operation make GARS O’Higgins in future increasingly attractive for polar orbiting satellite missions and a vitally important station for the global VLBI network. Future plans call for the development of an observatory for environmentally relevant research. That means that the portfolio of the station will be expanded including the expansion of the infrastructure and the construction and operation of new scientific instruments suitable for long-term measurements and satellite ground truthing.

The ecosystem-management approach laid down in the Arctic Council Marine Strategic Plan (AMSP) was not started on an empty purse. Some of the integrative (interdisciplinary) concepts of the International Northern Sea Route Programme developed during the period 1993–99 may prove useful in making the AMSP a document of operational utility and significance. The INSROP analysis was designed around two counterveiling variable: obstacles to and promoting factors of increasing navigation. These variables were applied for analysis to interactive relationships such as ice conditions and commerciality, ship design and depth conditions, sailing season and ice conditions, regional development and transit trade, environmental challenges and economic activities, military and economic activities, international ocean law and the NSR, insurance and navigation, and native cultures and navigation. The analysis of these relationships gave rise to integrative concepts like aggregated hot spots, issue-specific hot spots, cool spots, socio-biodiversity, single-value navigation, and multi-value navigation, all of which have a bearing on the realisation of the overarching aim of AMSP: to minimize the impact of navigation on the environment by integrative approaches across environmental, socio-economic, political, cultural, and other sectoral realms.

Organic-rich turf mounds, fertilised with bird droppings, may develop in the lee of obstacles, including either natural or human-made structures, boulders and rock cairns in exposed mountain and sub-Arctic and Arctic periglacial/proglacial environments. These boulder-leeside deposits consist mainly of organic materials intermixed with loess trapped in baffling agents (turf), and may sometimes contain archaeological features. Certain animal and bird species may also contribute to turf-mounds by frequenting these locations. Boulders and other natural and human-made obstructions are observed to have lichen plumes, principally Xanthoria spp?, lacing the tops and downwind side of the mound and fertilised by defecating birds and mammals. Turf mounds, consisting of organic soil, can be used for both relative and chronometric age dating, the buried peat providing 14C dates for archaeological context for specific mountain sites when artefacts are recovered. In addition, field and laboratory analyses of soils provide important palaeoenvironmental and geoarchaeological information about the sites. Examples are provided from a field site in the Norra Storfjället in the Swedish SubArctic.
