When policies are adopted, it seems reasonable to assume that they address a certain issue and provide means to mitigate specific problems. This seems the case with the EU's regime on trade in seal products, but it becomes evident that the goal formulation in this case is blurry and unclear. Taking animal welfare, the so-called ‘Inuit exemption’, and internal market harmonisation into account, this article examines the goals of the seal products trade regime and how they are applied. It becomes clear that the attainment of goals bears consequences that are unprecedented due to conceptual and formulation difficulties. Given the indistinct goal formulation during the policy-shaping process and the goal formulation in the policy itself, it seems fair to say that the regime does not aim to improve animal welfare standards in the commercial seal hunt, but rather aims to shut down the commercial hunt completely. This, however, affects Inuit and non-Inuit seal hunters equally and is inconsistent with secondary goals that are formulated in the EU's documents relating to the Arctic. Therefore, the seal products trade regime has consequences that challenge the EU's ambitions in the north.

This paper presents the results of a radiocarbon dating study of snow petrel (Pagodroma nivea) nest sites in central Dronning Maud Land, Antarctica. Mumiyo (a sub-fossilized accumulation of regurgitated proventricular oil) samples were collected from 15 snow petrel nest sites at nunataks in the northern Ahlmannryggen, Gjelsvikfjella, and Mühlig-Hofmannfjella.

Radiocarbon dating revealed Holocene ages of ca 8500 years and less for all but one of these mumiyo samples. A sample collected at S varthamaren in the Muhlig-Hofmannfjella was dated as old as ca 34,000 a BP, indicating that at least some areas of that mountain escaped the scouring action of glaciers during the last glacial period. Similar pre-Holocene ages have been determined for a small number of mumiyo samples in previous studies. Mumiyo accumulations from some nests indicate periods of occupation as long as 6000 years, whereas the radiocarbon age and volume of other mumiyo samples suggest short periods of frequent nesting activity. As expected, sub-samples extracted from the lower layers of mumiyo pieces generally displayed greater ages than sub-samples from upper layers of the same piece. However, there was no clear-cut correlation between the age of a mumiyo sample and its height above the present ice level. It is suspected that this lack of correlation is due to some of the mumiyo samples being displaced previously through rockfalls.

Controlling visitor impacts in polar regions continues to be important in both the Antarctic and Arctic. Concerns relate to impacts on the physical environment, cultural heritage, and host communities or scientific bases, as well as a recognition that safety and liability are major issues for governments, commercial operators, and local populations. Strategies for controlling tourists include visitor and operator codes and formal legislation. This paper summarises several approaches to visitor regulation in polar regions in order to illustrate the ways in which concerns about tourist impacts are being addressed. Similar issues arise throughout the polar regions, although in some places a particular emphasis might indicate a specific area of concern for a community, region, nation, or segment of the tourism industry. While a comprehensive strategy might be appropriate in many respects in the Arctic, it is also important to acknowledge the significance of more specific concerns. This paper first describes regulation of tourist behaviour and considers general issues of strategy effectiveness. Then it examines the approaches to visitor regulation used in the Antarctic and on S valbard as examples that may be of use in the further development of strategies in the Arctic. The paper then discusses an evolving strategy for control in the Northwest Territories, Canada. This strategy differs from these other approaches in that it targets a specific segment of the visitor population: those undertaking adventure expeditions.

An extensive terrestrial drainage system, centred on Algae Lake in southern Bunger Hills, is described. The 25-km-long Algae River is the third longest known in Antarctica after Onyx River (Wright Valley, Victoria Land) and Druzhby River (Vestfold Hills, Queen Elizabeth Land). Algae River receives meltwater from the Antarctic ice sheet, Apfel Glacier, and ephemeral and permanent snow banks in the ice-free area of the Bunger Hills. Water flows through a series of epiglacial lakes before reaching the extensive Algae Lake, which in turn has an outlet to Transkriptsii Gulf, a largely fresh-water, tidal epishelf lake connected to the ocean under the Edisto Ice Tongue and Shackleton Ice Shelf. Total flow from Algae Lake was estimated to be greater than 1 x 107 m3 a-1 from data collected in the 1986/87 summer. Some portions of the drainage system that were flowing during the 1946/47,1985/86, 1986/87, 1994/95, 1995/96, and 1998/99 summers were not flowing during the 1999/2000 summer, indicating the variable nature of discharge in the river and emphasising that parts of the drainage network may become disconnected readily.

Seventy years ago Fridtjof Nansen and thirteen companions drifted across the Arctic Ocean in the specially designed ship, Fram. The drift took three years because the sea ice cover governs movements of a surface ship, allowing a ship's commanding officer only an occasional freedom of choice of direction in which to move his ship. In contrast, during August 1958, the nuclear-powered submarine, USS Nautilus, under the command of Captain W. R. Anderson, crossed the Arctic Ocean in ninety-six hours, using the open sea that lies beneath the ice. In further demonstration of the capability of submarines to sail the Arctic Ocean, the USS Skate departed from New London, Connecticut, and the USS Seadragon from Pearl Harbour, Hawaii, proceeded to the Arctic Ocean, and on 31 July 1962 met each other at a prearranged point and time underneath the sea ice.

Several Arctic and Antarctic historic sites have now been extensively excavated and some, such as the Scott and Shackleton huts in the Ross Dependency of Antarctica, have been restored and opened to visitors. The huts of Mawson's Australian Antarctic Expedition 1911–1914, the sole expedition site of the historic age in Australian Antarctic Territory, have become a tourist attraction and the subject of controversy. One view favours bringing the main hut back to Australia for display in a museum, on the grounds that the hut is deteriorating and at present inaccessible to the Australian people: repatriation would preserve the hut and enable it to be viewed by a greater number of visitors. An alternative is to preserve the hut on site by covering it with a dome or re-cladding, replacing the timbers which have been seriously eroded, and retaining the site (but not at present the hut interior) as a tourist feature. The author argues in favour of preservation on site, retaining as much of the original fabric of the huts as possible, and proposes the formation of an informal network to exchange information among other researchers studying polar historic sites.

James Croll (1821–1890) was a Scottish scientist who made major, although still largely unrecognised, contributions to the theory of the effects of variations in the Earth's orbit on the global climate. He was the first to identify the importance of positive feedbacks in the climate system, especially the ice-albedo feedback, and he placed the astrochronological method on a sound footing. Croll's theory was the first to predict multiple ice ages. However, it was unable to place the end of the most recent glaciation more recently than 80,000 years ago, and as evidence accumulated throughout the 19th century for a much more recent date than this Croll's theory fell into neglect. We argue that this was particularly unfortunate since several of his key ideas were forgotten, and that this has delayed the development of the orbital theory of paleoclimate.

Radiocarbon age determinations on shells of the common mussel (Mytilus edulis) show that this species was present in central East Greenland from approximately 9500 to 5400 cal. years BP. It probably arrived first at the outer coast, at a time when the inner parts of the fjords were still occupied by glaciers. After perhaps a millennium it spread to the central fjord region where it lived for at least three millennia. The former occurrence of Mytilus edulis indicates higher sea surface temperatures than at present and more extensive fjord water, which may have been a consequence of higher summer insolation, perhaps amplified by changes in atmospheric circulation, bringing more warm air masses to the north. The timing of the Holocene thermal maximum in the lowlands of East Greenland was later than recorded in the Renland ice core. This delay was probably related to the continuing recession of the margin of the Greenland ice sheet in the early Holocene. The lingering decaying ice meant that large lowland areas were still ice covered, and other areas were cooled by the ice.

This paper explores ‘awkward Antarctic nationalism’ and builds on the critical scholarship that explores the contours and contradictions of everyday, mundane, banal and even hot polar nationalisms. The emphasis on ‘awkward’ is designed to draw attention to the resonances and affordances that are associated with Australian polar nationalism in and beyond the Australian Antarctic Territory/East Antarctica. Using the 2016 Australian Antarctic strategy: 20 year action plan as a starting point, it considers how bodies, ice cores and gateways are put to work in order to address a fundamental pressure facing all claimant states. That is how to reassure domestic audiences that claims to territory and access are safe, sovereign and secure without alienating others with whom one wishes to do business within a particular area of Antarctica. More broadly, the paper concludes that both claimant states and non-claimant states are rubbing up against one another in areas such as custodianship, environmental stewardship and polar science and logistics. This has implications for how we interrogate the ideals and practices of the Antarctic Treaty.

Historical records, recent observations, and geomorphological evidence indicate that rates of retreat and downwasting of the tidewater Stephenson Glacier, and concurrent expansion of ice-marginal melt-lakes, has increased by an order of magnitude since 1987. Melt-lake expansion is partly the product of greatly accelerated ablation of older, ice-cored twentieth-century moraines. The timing of these changes broadly coincides with reported increases in atmospheric and sea-surface temperatures around other sub-Antarctic islands, but correlates less well with changes along the northern Antarctic Peninsula, where warming has been more rapid. These recent changes in landscape character and geomorphological processes have implications for geodiversity, biodiversity, and cultural heritage values in this World Heritage Area. If the causal climatic warming is anthropogenic, it reinforces the fact that even the most remote and littlevisited nature conservation reserves may be compromised by off-site human impacts, confronting management authorities with difficult philosophical and practical issues.

There are two classes of airborne tourism in Antarctica: overflights without landing, and fl ights including landing. The earliest overflight was in 1956, but there were no regular flights until 1977, when Qantas and Air New Zealand began overflights with wide-bodied aircraft. A crash on Mount Erebus in 1979 that killed 257 people drew attention to the absence of effective planning, air traffic control, and rescue services. Landings began in the South Shetland Islands in 1982, when C-130 aircraft of Fuerza Aerea de Chile brought passengers from Punta Arenas. Since 1983, tourists have been accommodated in a Chilean government hostel. Flights to the interior began in 1984 when climbers were taken to the Sentinel Range by ski-equipped aircraft. Unmodified transport aircraft have been used since 1987, making wheel landings on naturally occurring bare ice in the Heritage Range. Tourists were taken from this site to the South Pole in 1988 by smaller, ski-equipped aircraft. Owing to the lack of conventional airfields in Antarctica, the future of intercontinental operations may depend on the development of additional airfields on bare ice. There are many possible sites. Most are near the periphery of the continent but some are in high latitudes, one only 300 km from the South Pole. A few of these will allow direct flights of unmodified passenger aircraft from South America, South Africa, Australia, or New Zealand. The possibility of 300 day-trippers stepping onto the ice from a Boeing 747 raises a variety of safety and environmental concerns. The challenge to the Antarctic Treaty System will be to reconcile the interests of governments, scientists, airlines, tour operators, tourists, and environmentalists.

This article explores the character of domestic political support for the Australian Antarctic Territory and Australia's involvement in the Antarctic Treaty System, using the linked frames of bifocalism and bipartisanship. After first unpacking these concepts it explores how they have shaped the extent and form of Australia's Antarctic endeavours from the 1930s to the present day. It is argued that the analysis shows that bipartisan commitment to Australian interests in Antarctica is framed through bifocalism: first, Australian national interests are closely linked to maintenance of the Antarctic Treaty and Antarctic Treaty System, and second, presentation of these national interests is not inimical to commitments to the Antarctic Treaty and Antarctic Treaty System.

The admission of China as an observer in the Arctic Council in 2013 was a significant step in the ongoing evolution of the country's Arctic policy, but Beijing is still concerned about being accepted as a regional player given its geography and arguably lack of an Arctic history. As the Arctic becomes more open to scientific and economic engagement, China wishes to develop the idea of the Arctic as more of an international space as opposed to strictly a regional one, and to allow non-Arctic states, such as China itself, to become accepted as Arctic actors. However, in order to avoid a backlash from the Arctic states and potential exclusion from the region's development, Beijing cannot effectively be a unilateral ‘norm-maker’ in the Arctic. Instead, China has sought to develop the identity of a regional ‘norm entrepreneur’, engaging the Arctic on many levels to promote the norm of partnerships between Arctic and non-Arctic actors to promote positive sum outcomes. Through engagement via several areas and governmental levels, Beijing hopes to succeed in being widely viewed as a ‘near-Arctic state’ which can contribute to new norms, and possibly new regimes, in an Arctic which shows many signs of becoming further internationalised.

Evidence from colony surveys and local Inuit knowledge strongly suggest that the Canadian population of ivory gulls (Pagophila eburnea) has declined dramatically. The observations of ivory gulls at sea presented here are consistent with this. Ivory gulls were observed during two cruises on the Russian icebreaker Kapitan Khlebnikov in the eastern Canadian high Arctic in August 1993 and 2002. Ivory gulls were seen 3.5 times more often in 1993 (n = 176) than in 2002 (n = 149), and, corrected for observation effort, four times more ivory gulls were seen in 1993 than in 2002. Ivory gulls are scavengers: they were never observed feeding on fish behind the vessel while ice-breaking, although black-legged kittiwakes (Rissa tridactyla) often were seen feeding in this way. Ivory gulls were observed scavenging around polar-bear (Ursus maritimus) kills in 1993 but not in 2002. By far the largest number of ivory gulls was seen near Grise Fiord in 1993. There, opportunities for them to scavenge were likely good at the community landfill as well as at Inuit and polar-bear kills due to complete ice coverage of the surrounding marine area. No ivory gulls were seen there in 2002. Observations of four individuals in 1993 and five individuals in 2002 near the southern end of Eureka Sound and in Norwegian Bay, 150 km from the nearest known breeding colonies, suggest that as yet undiscovered colonies might exist in this area. With three lines of evidence (colony surveys, local Inuit knowledge, at-sea surveys) now indicating population decline, urgent reassessment of the status of ivory gulls in Canada needs to take place.

The principal field activity of the A.N.A.R.E. party at Mawson during the 1957–58 summer was the determination of ice thickness along a section of the Antarctic plateau. In previous years the summer expeditions inland had concentrated on the survey and geology of the Prince Charles Mountains, south-east of Mawson. While this programme was continued in 1957–58 as opportunity presented, and in fact air photography of the ranges almost completed, the main I.G.Y. field effort was directed towards seismic ice-depth determinations. These were the responsibility of the Bureau of Mineral Resources, and a seismologist was seconded to the Antarctic Division, together with equipment for the purpose.

The traverse made lay southwards from Mawson, following approximately the meridian 62° 08′ E. It was known from prior air reconnaissance that a south-westerly spur of the Prince Charles Mountains system cut across the route in the vicinity of lat. 73° to 74° S., but the exact location was unknown. The intention was to map this spur, then skirt it to the west and resume the seismic traverse southwards.

South Georgia, one of the Dependencies of the Falkland Islands, lies in the South Atlantic Ocean between lats. 53° 50′ and 55° S. and longs. 35° 50′ and 38°15' W. The island is about 120 miles long from north-west to south-east and its greatest breadth is under thirty miles: it is heavily glacierized with an indented coastline and a backbone of high mountains rising to over 9000 ft.

This article compares Russian–Western cooperation in the Arctic and Space, with a focus on why cooperation continued after the 2014 annexation of Crimea. On the basis of this comparative approach, continued cooperation is linked to the following factors: (1) the Arctic and Space are remote and extreme environments; (2) they are militarised but not substantially weaponised; (3) they both suffer from ‘tragedies of the commons’; (4) Arctic and Space-faring states engage in risk management through international law-making; (5) Arctic and Space relations rely on consensus decision-making; (6) Arctic and Space relations rely on soft law; (7) Arctic states and Space-faring states interact within a situation of ‘complex interdependence’; (8) Russia and the United States are resisting greater Chinese involvement in these regions. The article concludes with the following contribution to international relations theory: The more that states need to cooperate in a particular region or issue-area, and the more they become accustomed to doing so, the more resilient that cooperation will become to tensions and breakdowns in other regions and issue-areas. This phenomenon can be termed ‘complex and resilient interdependence’, to signify that complex independence is more than a description. It can, sometimes, affect the course of state-to-state relations.

The north of Yakutia has long been known to be an immense storehouse of frozen disjointed bones of many hundreds of thousands of large Pleistocene mammals—mammoths, horses, woolly rhinoceroses, bison, musk-oxen— “horned cattle”, as the first Russian travellers called them. Such knowledge had a commercial value, of whichmore will be said below, for the quarrying of mammoth ivory has gone on for many centuries. In quality these tusks, which have lain in frozen ground for tens of millennia, are as good as those of modern African and Indian elephants and are sometimes two or three times larger. For naturalists, the greatest interest lies in the discovery of whole frozen bodies or of skulls and complete skeletons. Study of the position of these bodiesand their morphology and of the contents of their stomachs and intestines may answer the age-old question of why the mammoth (or woolly elephant), together with this rich assemblage of large herbivores, died out. Would even a partial restoration of such previously abundant life be possible there today?

The traditional methods of studying the marine biology of any coastline almost always involve the collection of plants and animals when the shore is exposed by the fluctuation of the tides. In the Antarctic, however, intertidal collecting is generally impossible due to the continuous abrasive action of floating ice, which scours this zone clean. Further difficulties are encountered in areas where fast ice extends out directly into the water, leaving no intertidal zone exposed. Thus our knowledge of the marine plants and animals of the Antarctic has been obtained largely through the use of the dredge. Skottsberg, in 1906, provided the first indication that there was, below the action of the ice, a rich growth of large marine algae. Unfortunately the bulk of his collections were lost when the Antarctic, the ship of the ill-fated Swedish Antarctic Expedition, 1901–03, was crushed and sunk by pack ice.
