Smith (1982) reported the discovery in 1981 of Antarctic hair grass Deschampsia antarctica Desv. on the largest of the Refuge Islands (68° 21' S) in Marguerite Bay, off the south-west coast of Antarctic Peninsula (Figure 1). This, was at the time the southernmost record of one of Antarctica's two native flowering plants. The only ecologically suitable area for vascular plants south of these islands appeared to be the Terra Firma Islands, 40 km along the coast, which Smith had been unable to reach due to dense pack ice. Earlier reports of grass and grass-like plants on the Terra Firma Islands could not be accepted as reliable in the absence of accurate descriptions, specimens or photographs, for elsewhere the bushy grey-green or yellow lichens Usnea antarctica and U. fasciata have been mistaken for grass when viewed from a distance. However, both Deschampsia antarctica and also Antarctic pearlwort Colobanthus quitensis (Kunth) Bartl., Antarctica's other flowering plant, have now been positively identified at a site on Barn Rock (68° 42' S, 67° 32' W) in the Terra Firma group.

Differential synthetic aperture radar interferometry (DInSAR) exploits the coherence between the phases of two or more satellite synthetic aperture radar (SAR) scenes taken from the same orbit to separate the phase contributions from topography and movement by subtracting either phase. Hence pure terrain displacement can be derived without residual height information in it, but only the component of movement in line-of-sight direction is represented in a differential interferogram. Comfortlessbreen, a recently surging glacier, flows predominantly in this direction with respect to the European Remote Sensing satellites ERS-1 and ERS-2. Four C-band SAR scenes from spring 1996 were selected because of the high coherence between the respective pairs of the 1-day repeat-pass tandem mission of the ERS sensors. 2-pass DInSAR is performed in combination with a SPOT5 (Satéllite pour l'Observation de la Terre 5) SPIRIT (SPOT5 stereoscopic survey of Polar Ice: Reference Images and Topography) digital elevation model (DEM) from 2007. The different processing steps and intermediate image products, including unwrapping and generation of displacement maps, are detailed in order to convey the DInSAR processing chain to the beginner in the field of interferometry. Maximum horizontal displacements of 18 to 20 cm d−1 in ground range direction can be detected at the glacier terminus, while a few centimetres per day characterised most of the middle and upper portions of Comfortlessbreen in spring 1996.

This article examines the implementation of the principles of openness, transparency and public participation in the decision-making regarding the conditions for uranium mining in Greenland from a legal and political perspective. The time frame covers the period from the exploration for minerals before World War II to 2016–2017 when the current Greenlandic authorities prepared a licence for a project of extraction of rare earth elements and uranium in Kvanefjeld. It is shown that the issue of openness, transparency and public participation in Greenland is a longstanding issue and that the current governance does not permit public access to a draft environmental impact assessment report, impairing public participation in decision-making, and preventing the environmental consequences of these activities from being considered as a public concern. It is argued that sovereignty–its consolidation and the accession to it–has impacted the design of governance in Greenland and that the constraints put on the full implementation of the legal principles of openness, transparency and public participation in the governance of uranium mining in Greenland, amongst other factors, point to a current hybrid political and legal order in the context of a political agenda of independence.

Two terrestrial Crustacea, Puhuruhuru patersoni (Amphipoda: Talitridae) and Styloniscus otakensis (Isopoda: Styloniscidae), were discovered on sub-Antarctic Macquarie Island in 1991 and 1992, respectively. Each species was identified as having been described, and previously only known, from South Island, New Zealand and from some of New Zealand's southern offshore islands. The distributions of the two species on Macquarie Island have been mapped in detail on four occasions over the last fifteen years, each mapping extending previously existing distributions or showing changes from the earlier records. Details of all four years' mapping are figured. It is concluded that these species were most likely introduced between 1810 and 1919 and that populations of the amphipod have not expanded to any extent in the twelve years between 1992 and 2004 but that the isopod has slightly increased its range. Both species are macrodetritivores, a trophic group not well represented on the island, so there is the possibility of an irreversible change to the Macquarie Island ecosystem if they become more widespread with warming climates. However no such change has yet been observed. The advantages and feasibility of removing these two exotic species from the island is discussed, as are the possible routes by which the species were introduced to the island.

This article describes a framework within which an initial strategy could be developed for managing commercial exploitation of marine living resources of the Southern Ocean, particularly of krill and fish, in accordance with Article II of the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR). Quantitative predictions involving multi–species models are needed to assess any indirect impacts of fish or krill exploitation, and also for management to restore depleted populations. This article recommends research to provide the knowledge necessary for the models (identifying key species, estimating their demographic status, and experimental interference), and suggests interim management action to delimit management areas, agree target levels for stock–size, and monitor stocks. Early efforts to model the fishing operation are particularly recommended.

About fifty species of terrestrial arthropods have been collected in Antarctica; these include mites, ticks, springtails, sucking lice, biting lice and flies. The mites include both free-living and parasitic forms, the springtails and flies are free-living, and the ticks and lice are parasitic. The ticks, parasitic mites, and biting lice are associated with birds, and the sucking lice with seals. The number of species are about equally divided between free-living and parasitic forms. The ability of insects and mites to survive the very low winter temperatures and frequent strong winds of Antarctica is of considerable interest; judged in relation to commonly accepted ideas of tolerance, the environment is extremely forbidding.

Seal hunting remains of vital importance to Inuit culture, but the value of seal meat extends beyond nutritional and dietary requirements. This article focuses on the contemporary ideology of subsistence in a Greenlandic scaling community, with particular reference to the sharing of seal meat. Seal hunting is not cash-oriented and therefore seal meat is not regarded as a commodity. When it is shared or given away as a gift it expresses the relationships people share with each other. Sharing cements bonds of kinship and close social association and remains a distinctive statement of community.

Cryoconite holes have ecological and biotechnological importance. This article presents results on culturable cryophilic yeasts and filamentous fungi isolated from cryoconite holes at Austre and Vestre Brøggerbreen glaciers, Svalbard. Based on DNA sequence data, these were identified as Rhodotorula sp., Thelebolus sp., and Articulospora tetracladia. Amongst these, Articulospora tetracladia (88.7–89.4% gene similarity with 5.8S rDNA) is a novel species, yet to be described. Filamentous fungus Articulospora sp. Cry-FB1 and Cry-FB2, expressed high amylase, cellulase, lipase and protease activities while yeast Rhodotorula sp. Cry-FB3 showed high amylase and cellulase activity. Thelebolus sp. Cry-YB 240 and Cry-YB 241 showed protease and urease activities. The effects of temperature, and salt on the growth of the cultures were studied. Optimum temperature of growth was on 10ºC at pH 7.0. Filamentous fungi and yeast in the cryoconite holes possibly drive the process of organic macromolecule degradation through cold-adapted enzyme secretion, thereby assisting in nutrient cycling in these supraglacial environments. Further, these cryophilic fungi, due to their enzyme producing ability, may provide an opportunity for biotechnological research in the Arctic.

In regions periodically subjected to falls of snow, major obstacles to the movement of men and vehicles are caused rather by the formation of drifts than by the uniform deposition of snow. Even in countries where snow-fall is not heavy, drifting can occasionally cause a breakdown of transport over a large area. Drifts form when snow-bearing winds meet obstacles which cause eddies in the wind stream and a local reduction in wind speed. The snow is deposited out of the wind stream into these regions of comparative calm, and the process continues for as long as an obstacle is effective in reducing wind speed.

Canada and the USSR together possess most of the territory in the Northern Hemisphere underlain by permafrost or perennially frozen ground. As about one half of the land area of each country is affected, the permafrost region of the Soviet Union is 2½ times larger than that of Canada. Outside mountainous regions, permafrost extends southward in Canada to the southern tip of James Bay at lat 51° N (Brown, in press). Permafrost extends farther south in eastern Asia, however, and occurs in Outer Mongolia and Manchuria to about lat 47° N Fig 1) (Baranov, 1959; Nekrasov, 1962).

This article analyses the historical conditions and technical, social, commercial and political factors that have contributed to the revival of longline fishing in Iceland. Longline fishing practices have had important consequences at both the local and the national levels. This article deals, firstly, with the juridical and historical conditions of the development of small boat fishing practices since the beginning of the 1990s and the process through which small boats became progressively larger. Secondly, the paper describes the evolution of longline fishing practices and focuses more specifically on the technical, commercial, social and professional aspects of a new version of longline fishing that was developed in response to new marine management rules. It then deals with a specific kind of competitiveness that those living in coastal villages established to re-boost the local economy and discusses what has happened to small boat owners since 2000. The conclusion highlights the way longline fishing, by reconnecting social ties, takes part in the construction of contemporary Icelandic culture.

Water related activities result in a large number of fatalities annually throughout Canada, especially in the Canadian north, where drowning rates are up to ten times the national average. This study used participant observation, semi-structured interviews, and archival research to understand why residents of Tuktoyaktuk, Northwest Territories (NWT) rarely wear lifejackets. Three themes emerged. Firstly residents largely perceive lifejackets to be inaccessible, secondly drownings are attributed to factors other than failing to wear a lifejacket and thirdly lifejacket use is not encouraged by important individuals in the community. It is suggested that successful lifejacket promotion for this population requires drowning prevention programmes that move away from simplistic approaches that encourage people to wear lifejackets and instead must utilise an approach that addresses each component of the theory of planned behaviour (TPB).

A geochemical study of the Severnaya Dvina estuary was carried out during two oceanographic cruises to the White Sea. The amount and distribution of trace (Mn, Co, Cu, Ni, Pb, and Zn) and major (Al and Fe) elements in suspended particulate matter and sediments were determined. The main source of most metals studied was river discharge. A metal speciation study showed that the prevailing form is in the estuarine sediments, the minerals of which incorporated 60–99% of the total metal contents. Two zones of metal accumulation were found in sediments that were considered as local geochemical barriers within the major river–sea barrier.

During an early summer visit in 2000, mosses were collected from sites around Heard Island. Three species, Bryoerythrophyllum recurvirostrum (Hedw.) P.C.Chen, Philonotis cf. tenuis (Taylor) Reichardt and Syntrichia filaris (Müll.Hall) R.H. Zander have been added to the list of moss species known from the island, bringing the total to 40 moss taxa. Syntrichia anderssonii (abcngström) R.H. Zander was found with sporophytes, whereas previously its sporophytes were known in the sub-Antarctic only from Macquarie Island. Extensions of range on Heard Island have been recorded for several species. There are few geographical differences in species composition between locations around the island, provided appropriate habitats exist.

In a context of rapid climatic change in the Arctic, the fast melting of permafrost, the decline of glaciers and the melting of sea ice created perceived strategic and economic opportunities for the littoral states. The attention of states beyond the region was also attracted. For example China, without direct access to the Arctic, displays an interest in Arctic research, natural resources, and shipping potential. However, its diplomatic, economic, political and scientific efforts in this region arouse negative reactions among western media. They often draw up a portrait of an ambitious and arrogant China, ready to push aside the sovereignty of the Arctic countries to defend its own interests in the Arctic. From this perspective, it seems relevant to analyse China's activities in the region and to try to assess Beijing's strategy, which seems more driven by opportunism than by a long-term desire to challenge the littoral states’ sovereignty.

When geographers recommended the exploration of the Antarctic regions at the close of the nineteenth century, Germany and Britain were eager to do their best. The promoters of Antarctic research, such as Georg von Neumayer (1826–1909) in Hamburg and Clements Markham (1830–1916) in London, could finally raise enough money to build national flagships for science. Despite unfavourable political circumstances, due to political rivalry between Germany and Great Britain, the leaders of the expeditions — Erich von Drygalski (1865–1949) and Robert Falcon Scott (1868–1912) — agreed to a scientific collaboration with regard to meteorological and magnetic measurements in Antarctica during 1901–1903, which later was extended until 1904. This paper reveals that favourable circumstances such as the International Geographical Congresses in London (1895) and Berlin (1899) played a major role in increasing scientific interest in and public support of Antarctic research, ultimately leading to international collaboration.

Vertical accelerometers deployed on fast ice in Raudfjorden, Svalbard in early summer 1983 recorded characteristics of ice-coupled waves at the ice edge and during their passage under die ice sheet. Subsequent analysis indicated an unexpected increase in amplitude of waves of all periods some 20 to 30 m in from die ice edge. This is associated with a pair of heavily-damped waves, which become especially relevant at or beyond some critical angle and decay rapidly with distance from the edge; their coalescence may account for the increase in wave amplitude, and explain why ice tends to break out in strips parallel to the ice edge.

Seismic survey activities in the western Beaufort Sea, involving ships and sound production, were monitored in autumn 1982 for their possible effects on migrating Bowhead whales Balaena mysticetus. The study, begun in 1981 by die Minerals Management Service of the US Department of the Interior, covered offshore waters between the Alaskan coast and 72°N. Distribution, behaviour and numbers of whales were recorded, and procedures were established for monitoring and controlling seismic activities in their presence.
