Antarctic tourism has experienced a boom period over the last thirty years. Beginning in the 1980s, the number of tourists who visited the continent annually began to rise sharply, and within the space of twenty years the numbers had increased by more than six hundred percent. Despite a global recession and downturn in visitor numbers over the last two austral seasons, the expectation is that Antarctic tourist numbers will trend upward again as the world tourism market recovers and the demand for Antarctic visits increases. In a continent renowned both as the last great global wilderness and as a place dedicated to scientific research in the interests of humankind, tourism on this scale presents a formidable range of issues for the Antarctic Treaty Consultative Parties (ATCPs) to contend with. This article suggests that the rapid growth in Antarctic tourism, and the impacts of that tourism coupled with the lack of a comprehensive regulatory and management framework for tourism now pose a considerable challenge to both the Consultative Parties and to the Antarctic Treaty System (ATS) itself. The obligations and duties of the ATCPs under the Antarctic Treaty and other ATS instruments require a robust, strategic response by them to the issues and concerns generated by the growth of tourism. What is needed, it is argued, is for the parties to initiate a more interventionist pro-active policy approach to create a holistic, binding tourism framework so that they may fulfill more effectively their stewardship and governance roles in Antarctica, prevent degradation of Antarctica's environment, and reduce risks to tourists themselves.

This paper assesses the vulnerability of Arctic fishing communities. We hypothesise that climate change related trends, such as increasing temperature and altered seasonality, and shocks, such as the breakdown of the Soviet Union or new fishing regulations, increase vulnerability of local Arctic peoples and compromise the sustainability of their livelihoods. Research shows that over recent decades local people have observed environmental changes and a significant decrease in the number of fish caught. Fishing regulations introduced after the collapse of the Soviet Union burdened fishers with quotas and temporal limitations that have hindered their fishing activities. While the adaptability of traditional fishing techniques to seasonally changing conditions might indicate the potential to adapt to future conditions under climate change, fishing regulations appear to limit this potential to adapt.

Karl Weyprecht has left an unforgettable record of polar exploration, but has himself tended to be forgotten. His fame rests not so much with his work in the Arctic, which included the discovery of Zemlya Frantsa-Iosifa, but on the series of international scientific programmes which he initiated in 1875 with the first International Polar Year (IPY), 1882–83. International scientific programmes can be traced back to 1751, when observations of the parallaxes of the Moon, Mars and Venus were made at six stations in the Northern Hemisphere and at one in the Southern. The most recent, the World Climate Research Programme, organized jointly by the World Meteorological Organization (WMO) and the International Council of Scientific Unions (ICSU), began in 1980.

The preservation and conservation of living resources was one of the original stated objectives of the Antarctic Treaty, 1959. The harvesting of animals near bases for food, especially Weddell Seals Leptonychotes weddelli received particular attention at the Fourth Meeting of SCAR, 1960 (Polar Record,1961) and several regulations were suggested including: a permit required before killing, records to be kept of animals killed, and use of alternative food where possible. Annex D, Section (b)i states “… Without detailed biological research it is impossible to assess the permissible annual crop which the various [Weddell] seal colonies would stand, but it is certain that this figure is being seriously exceeded in many areas.”

The fur seal population of the South Shetland Islands, Antarctica, was intensively hunted by sealers from the discovery of the islands in 1819 to the early 1820s, by which time the seal numbers were so depleted that sealing became uneconomic. Sealing was revived for both fur seals and elephant seals at several periods later in the century. Sealers were put ashore in gangs and built makeshift shelters in which to live, and also occupied caves. Many of these have been identified on the various islands of the South Shetlands, and a number have been excavated. The paper addresses some of the management issues facing the conservation of these sites, which include accelerating tourism, disturbance by scientific researchers, disturbance by animal activity, burial or erosion by drifting sand, and climate change.

During Leg 119 of the Ocean Drilling Program, between December 1987 and February 1988, six holes were drilled in the Kerguelen Plateau, southern Indian Ocean, and five in Prydz Bay at the mouth of the Amery Ice Shelf, on the East Antarctic continental shelf. The Prydz Bay holes, reported here, form a transect from the inner shelf to the continental slope, recording a prograding sequence of possible Late Paleozoic to Eocene continental sediments of fluvial aspect, followed by several hundred metres of Early Oligocene (possibly Middle Eocene) to Quaternary glaciallydominated sediments. This extends the known onset of large-scale glaciation of Antarctica back to about 36–40 million years ago, the sedimentary record suggesting that a fully developed East Antarctic Ice Sheet reached the coast at Prydz Bay at this time, and was more extensive than the present sheet. Subsequent glacial history is complex, with the bulk of sedimentation in the outer shelf taking place close to the grounding line of an extended Amery Ice S helf. However, breaks in the record and intervals of no recovery may hide evidence of periods of glacial retreat.

A single chinstrap penguin (Pygoscelis antarctica), which had moulted at the South Shetland Islands, was subsequently tracked during 120 days at sea in the austral winter using a global location system (geolocation) based on light intensity. The bird moved east along the Scotia Ridge to a point approximately 300 km west of the South Sandwich Islands and approximately 1600 km away from the colony in which it had moulted. It spent more than 60% of its time in open water north of the edge of the pack ice.

Stream icings are a unique type of river ice that form in a portion of a stream channel which freezes deeply enough to restrict channel flow. Icings are usually found in Arctic and sub- Arctic regions because of the prevalence of permafrost and seasonally frozen ground in these regions. Hydraulic pressure builds up at the point of constriction as the river ice and permafrost thicken during the freeze-up period (Fig 1). Water is forced up through cracks in the river ice and freezes upon exposure to the cold air. This process continues in successive overflows until the source of water is exhausted.

This paper examines the development of Malaysia's position on the ‘Question of Antarctica’ and its relationship to the Antarctic Treaty System (ATS). Malaysia's challenges to, and criticisms of, the Antarctic Treaty Consultative Parties (ATCPs) are mapped from 1982 to 2004, indicating a shift from challenging the ATS to engagement with the ATCPs. The paper highlights how Malaysia's position on the ‘Question of Antarctica’ reflected a mix between domestic political concerns and its international and regional interests. The mix between domestic and international interests is reflected in the ongoing involvement of Malaysian Prime Minister Mahathir bin Mohamad, including his retirement in 2003, in shaping Malaysia's position, from initiating the challenge to the ATS in 1982 to recommending that Malaysia join the ATS in 2004. Mahathir's domestic agenda, most notably through Malaysia's ‘Vision 2020’ development program is identified as providing an impetus for change, increasing Malaysian scientific interest in Antarctica and the Southern Ocean.

For several years. Geophysical Survey Systems, Inc has been using an impulse radar system as a shallow subsurface exploration tool for engineering applications. Recently this system has been applied to the measurement of ice thicknesses both on sea-water and fresh-water ice. In the course of a feasibility study performed in December 1972, thebasic operating parameters and limitations of the tool when operated on ice were determined. Following the feasibility study, operational surveys were performed totalling approximately 11 crew-months and covering in excess of 1 500 km of survey route at several locations in the Canadian Arctic. The technique is known as Electromagnetic Subsurface Profiling (ESP), and it can be considered the electromagnetic equivalent of the single-trace acoustic profiling methods used for marine subbottom profiling. In practice, ice-thickness profiling is done by towing a sled-mounted antenna behind a tracked vehicle containing the impulse system (Fig 1). Real-time profile data are displayed graphically on a strip-chart recorder. The data may also be recorded on magnetic tape for later processing and playback.

Norse immigrants from Europe settled in southern Greenland in around AD 985 and managed to create a farming community during the Medieval Warm Period. The Norse vanished after approximately 500 years of existence in Greenland leaving no documentary evidence concerning why their culture foundered. The flooding of fertile grassland caused by late Holocene sea-level changes may be one of the factors that affected the Norse community. Holocene sea-level changes in Greenland are closely connected with the isostatic response of the Earth's crust to the behaviour of the Greenlandic ice sheet. An early Holocene regressive phase in south and west Greenland was reversed during the middle Holocene, and evidence is found for transgression and drowning of early-middle Holocene coast lines. This drowning started between 8 and 7ka BP in southern Greenland and continued during the Norse era to the present. An average late Holocene sea level rise in the order of 2–3 m/1000 years may be one of the factors that negatively affected the life of the Norse Greenlanders, and combined with other both socio-economic and environmental problems, such as increasing wind and sea ice expansion at the transition to the Little Ice Age, may eventually have led to the end of the Norse culture in Greenland.

Chemical factors that are essential in frost heaving of soils are examined through consideration of the process of ice formation in soils and the role of temperature gradients in generating water potential gradients in freezing soils. Unfrozen films are maintained around soil particles in frozen soils. The osmotic potentials at the ice–water interface of the unfrozen films and in the frozen fringe, the thin zone between the frozen and unfrozen soil, generated by dissolved salts and exchangeable cations that satisfy soil particle surface charge, are controlled by the local temperature. The coldest location and the most negative osmotic potentials at the ice–water interface are located immediately below the base of the ice lens, in the unfrozen films that separate the underlying soil particles from the ice lens. An osmotic potential gradient is generated because the osmotic potential at the water–ice interface in the frozen fringe becomes less negative with increasing temperature and distance from the ice lens. As water freezes onto the ice lens, re-supply of water to the unfrozen film along the osmotic potential gradient is the temperature-gradient-induced mechanism that generates the force that lifts the overlying frozen soil. Models that recognize this driving mechanism should improve predictions of soil freezing and frost heave, analysis of contaminant transport in freezing and frozen soils, and other aspects of the soil-freezing and frost-heave processes.

This note addresses the recent announcement regarding Argentina's submission to the UN Commission on the Limits of the Continental Shelf. While the commission considered much of Argentina's submitted materials regarding the outer continental shelf (and sovereign rights that accrue to the seabed), it deliberately excluded areas of controversy including the Falkland Islands and Antarctica. What should be of interest to Polar Record readers is how consistently international media, including British journalists, misunderstand international maritime law and ‘stoke’ the fires of Argentine and British nationalisms. The Argentine government, however, was not an innocent party and its own press releases were ambiguous on the matter concerned, even if the commission had recognised the merit of much of their scientific-technical submission.

This paper examines the international response to India's 1956 proposal to raise the ‘Antarctic Question’ at the United Nations. It focuses in particular on the uneasy alliance that developed between the British Commonwealth and Latin America in opposition to the Indian proposal. Although Great Britain, Argentina, and Chile were bitterly disputing the sovereignty of the Antarctic Peninsula region, they shared a common desire to keep the southern continent off the agenda of the United Nations. This ability to work together for common goals, despite their differences, set an important precedent for the Antarctic Treaty that would be signed in 1959. In this way, opposition to the Indian proposal, more than the proposal itself, played an important role in the history of Antarctica in the 1950s. Latin American opposition to the proposal helped to fragment any ‘anti-imperial’ coalition that might have developed in Antarctica. This fragmentation helps us to place the Antarctic Treaty System into the framework of post-colonial studies.

A breeding colony of ivory gulls was discovered on an ice floe in northeast Greenland in August 2008. The ice floe resembled nearby islands in that it was covered with a thick layer of gravely moraine, and furthermore its position was fixed throughout most of the breeding season as the surrounding first year ice only broke up in mid August when most of the gull chicks had fledged.

Sphagnum moss has been used globally as an indicator of climate change. Since continuous meteorological recording started in the late 1940s, there has been a marked change in the climates of Southern Ocean islands. The distribution of Sphagnum on Macquarie Island appeared to be expanding through the 1980s. All patches of Sphagnum were mapped in the 1992/93 austral summer, with 112 Sphagnum moss patches (<3 m2) and 12 larger (≥3 m2) patches recorded. The vast majority of sites recorded were lowland coastal, with a few sites around plateau lakes. The area of moss beds ranges from 0.03 m2 to 32.4 m2. A total of 23 sites were pegged and tagged by 1996, but only 14 of these sites still had Sphagnum moss present by 2004. It is considered that the climatic conditions (higher than average temperatures and wind speeds and lower than average humidity and precipitation) that occurred between April 1999 and May 2000 would have resulted in a period of desiccation that accounts for the destruction of the smaller and/or shallower Sphagnum beds on the island. It is highly likely that both the spatial distribution and size of Sphagnum moss beds on Macquarie Island will continue to decline with predicted changes in sub-Antarctic climate.

Prolonged chasing of an adult reindeer (Rangifer tarandus) by a polar bear (Ursus maritimus) was observed both on land and in the sea, in Magdalenefjorden, northwest Spitsbergen. Polar bears were also observed catching black guillemot (Cepphus grylle) in the sea in northwest Spitsbergen and feeding on chicks in the arctic tern (Sterna paradisea) colony in Hornsund, southwest Spitsbergen. While feeding on seabird species is unsurprising, the prolonged chasing of adult reindeer is unusual for polar bear hunting behaviour. The few documented cases of polar bear hunting reindeer consist of either surprising and killing resting/sleeping prey or stalking and a short rapid chase of the reindeer. Our observations describe new feeding habits of polar bears that may be in response to decreasing seal availability due to shrinking sea-ice cover in the Arctic.

In outline, the Antarctic continent crudely resembles a pear. It is indented on two sides by arms of the ocean, the Ross and Weddell Seas. These indentations are even greater than an outline map would suggest, for the seas extend far toward the interior of the continent beneath the world's two largest floating ice shelves, bearing the names of their respective discoverers, the English sea captain, Ross, and the German explorer, Filchner.

Over the last four decades, Norwegian rule on the Svalbard islands has developed gradually, from being virtually non-existent to firm. This study explains these developments in Norwegian jurisdiction both from a perspective of international relations and within a paradigm of domestic politics. It finds that external forces have been the permissive causes of change, while internal forces represent the efficient causes. Norway's incremental strengthening of jurisdiction, notably from the mid-1970s onward, has resulted in an unprecedented Norwegian grip on the Arctic islands in which the other parties to the 1920 Svalbard Treaty seemingly acquiesce.

We argue that the current understanding of the Arctic as a region fraught by increasing tension and competition under conditions of climate change is an incomplete story. It ignores many salient developments in furthering co-operation and human security agendas, and marginalises some of the more complex and interesting developments within the region. Such changes in ‘natural states’ do not, in and of themselves, create geopolitical and political instability. Rather, it is the way in which change is understood as a problem for institutional and international organs that creates conditions for co-operation or competition. In the Arctic today, the balance is tipped in favour of co-operation, but the situation is complex and many actors have vested interests.
