Bowhead whale bones in prehistoric Thule Eskimo contexts have been examined since 1975 in the central Canadian Arctic. Approximately 10,500 bones, representing almost 1000 animals, have been counted on the shores of six adjacent islands. Comparisons of Thule-derived bowhead samples with live Beaufort Sea samples and Early Holocene samples indicate that Thule Eskimo hunters selected yearlings and two- to three-year-old subadults, to the almost complete exclusion of calves and adults. Almost all bowheads found at Thule sites measure 7–10 m in length, estimated by regression analyses based on Alaskan bowhead skeletons of known size. Archaeological bowhead bones represent several stages of past hunting and processing behavior, including selective hunting, beach flensing and meal/blubber caching, winter house construction, and bone re-use from house ruins. The availability and abundance of bowheads were primary determinants of Thule subsistence-settlement patterns in this region. Archaeological whale bones arc a nonrenewable cultural resource of the New World Arctic that deserve study and protection.

This paper describes the historical and contemporary associations between Hobart (Tasmania, Australia) and Antarctica and the Southern Ocean. This association is traced from the sealing and whaling industry, through early exploration and scientific expeditions, to contemporary issues of institutional and educational development and tourism. I is argued that this polar link has placed Hobart at the centre of some important Antarctic and Southern Ocean developments.

On 19 March 1930 the German geologist, Hans K.E. Krüger, accompanied by a Dane, Åge Rose Bjare, and an Inughuk, Akqioq (the latter driving their dog sledge) set off westwards from the Royal Canadian Mounted Police post at Bache Peninsula, Ellesmere Island; two support sledges, driven by Inughuit, escorted them. It appears to have been Krüger's intention to study the geology of the coasts of the outer islands of the Canadian Arctic archipelago and to carry out soundings of the continental shelf and slope. The two support sledges turned back at Depot Point, Eureka Sound. Krüger, Bjare, and Akqioq were never seen again. This article reviews Krüger's background, his preparations for the expedition (which included two summers of field work in West Greenland and a wintering in northwest Greenland), and the extensive searches mounted by the RCMP in 1931 and 1932. Finally, it analyzes the evidence provided by three messages left by Krüger and subsequently recovered, with a view to making an educated guess as to the fate of the expedition.

During the resurgence of Arctic exploration in the early years of the nineteenth century, James Rennell was the leading British geographer. He had a deep interest in exploration, and was a close friend of many naval and scientific men involved in Arctic research. Rennell used the observations of a number of explorers in his major work on the currents of the Atlantic — the first scientific treatise on ocean currents. These observations led Rennell to form opinions on where northwest passages would and would not be found, in particular, that Prince Regent Inlet would prove to be a cul-de-sac. Rennell was also doubtful of the practicality and usefulness of such passages — his brief, commonsense dismissal being in stark contrast to many statements of his contemporaries. This paper sets out his relationship with the explorers of the time and his role as a scientific interpreter of their data.

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 concludes an account of the Prince AIbert expedition of 1850, which began in Polar Record 29 (169): 127–142 (1993); see Part 1 formaps. In 1850 Lady Franklin sent out the first other private expeditions in search of her husband and the crews of HMS Erebus and Terror, lost in the islands of the Canadian Arctic. The expedition sailed in Prince Albert, a vessel Lady Franklin acquired for the purpose. Its aim was to winter in Prince Regent Inlet and explore the area to the west, using two separate boat parties. These parties were to be under Commander Charles Codrington Forsyth, RN, the captain of the ship, and William Parker Snow. After passage to Prince Regent Inlet, Forsyth turned back because he was prevented from penetrating the inlet further than Fury Beach by what was regarded as unbreachable ice. Prince Albert then passed near Cape Riley, where Snow obtained information concerning relics that had been found by another expedition and that indicated that Franklin had wintered in that vicinity. News of this and further relics were brought back to Britain by Forsyth. The return caused much disappointment to Lady Franklin. She determined to send Prince Albert out again with a different commander. Snow wished to have that post, but it was allocated to William Kennedy.

This study is an analysis of the events surrounding the expedition, with reference to the light they throw on the personalities involved. It is suggested that the main reason for the failure was that the preparation was mismanaged. No efforts were made to secure the appointment of people who had sufficient similarity of interests or background to be an effective team. Forsyth found the situation on board such that he decided to conclude the voyage as soon as a reasonable excuse for returning presented itself.

Between late March and May, from 1971 through 1979, we surveyed 74,332 km2 of sea-ice habitatin the eastern Beaufort Sea and Amundsen Gulf in the western Canadian Arctic. We defined seven sea-ice habitat types and recorded sightings of polar bears and their tracks in each to determine their habitat preferences. 791 bears (including cubs) and 6454 sets of tracks were recorded. 42.3%, 39.7%, and 15.6% of the bears were seen on floe-edge, moving ice, and drifted fast-ice habitats, respectively. Significant differences in habitat preferences were shown by bears of different sexes and age classes. Adult females accompanied by cubs of the year were the only group that showed a strong preference for fast ice with drifts, probably because they could feed adequately there while avoiding adult males that might prey upon their cubs. The highest densities of seals are found in floe-edge and moving ice habitats and this likely explains the predominance of bears there. Lone adult females and females with two-year-old cubs, adult males, and subadult males were found two and one-half to four times more frequently than predicted in floe-edge habitat. Since there are no data to suggest seals are more abundant along the floe edge than in moving ice habitat, the preference of these groups of adult polar bears for the floe edge in spring may be related to reproductive behavior.

The drift of Hobson's Choice Ice Island from the Arctic Ocean into the channels of the Queen Elizabeth Islands, Northwest Territories, Canadian Arctic, between February 1988 and August 1992, was monitored by a Système Argos satellite-positioning buoy. During the period August 1991 to May 1992, the ice island was imaged by synthetic aperture radar (SAR) aboard the ERS-1 satellite. The buoy data show that Hobson's Choice entered Peary Channel (between Axel Heiberg Island and Ellef Ringnes Island) in October 1988. Subsequently, between mid-August 1991 and November 1991, it drifted rapidly south to Queens Channel (60 km north of Cornwallis Island). The SAR data corroborate the buoy data and also reveal that at least six other ice islands entered the Queen Elizabeth Islands' channels with Hobson's Choice. The SAR imagery also recorded the fragmentation of Hobson's Choice between mid-October and mid-November 1991. The buoy and SAR data are conclusive evidence that ice islands do leave the Arctic Ocean via the northwestern channels of the Canadian Arctic archipelago. The observed drift occurred when there was extensive break-up of fast ice in the inter-island channels caused by above average summer temperatures, in combination with favourable atmospheric circulation and surface winds that drove the ice islands into and through the channels.

Geographically separated by only 64 km, the Siberian Yupik-speaking communities of Gambell and Novoye Chaplino have endured a politically mandated separation of 40 years. During this period these two small, native comm unities have experienced enormous changes, changes often engendered by the social and economic policies of their nation states. The abandonment of small, native communities in Chukotka under the Soviet policy of ‘settlements without prospects’, the forced resettlement of Chaplino to Novoye Chaplino, and the reorganization of cooperatives into state farms have all had serious detrimental consequences for the organization of subsistence activities in this community. Gambell—with very little economic infrastructure, high unemployment, increased social problems, and some federaland state-mandated management of their natural resources — has managed to maintain high levels of subsistence production. The native language is spoken by youngsters in Gambell but not in Novoye Chaplino. Other important cultural features such as sharing, bride service, and ivory carving have been maintained in Gambell but have been lost in Novoye Chaplino. Contacts between the two communities under the recent policy of glasnost' may bring a revival of these practices back to Novoye Chaplino.

Bowhead whales pass near or through offshore oil and gas lease areas in the northeastern Chukchi Sea during their westward migration each autumn. Results of aerial surveys conducted from mid-September through October 1982–1990 indicate that whale distribution overlapped lease area boundaries north and east of Point Barrow, Alaska. Bowhead relative abundance was high throughout the fall in nearshore sub-blocks east, north, and southwest of Point Barrow, with somewhat lower indices in offshore sub-blocks northwest of Point Barrow.

The background to the development and implementation of environmental impact assessment procedures in Antarctica is reviewed and the principles and procedures of the Protocol on Environmental Protection to the Antarctic Treaty (the Madrid Protocol of 1991) are outlined. The difficulties in determining the appropriate level of assessment and the practical, operational aspects of carrying out the evaluations are examined. Particular attention is given to the meaning of terminology in the Protocol, the interpretation of environmental principles and standards, alternatives to the proposed activity, the requirements for sufficient information, the process of obtaining and taking into account public comment, the monitoring of environmental indicators, and the practical implications where an activity needs to be suspended, cancelled, or modified. The workloads generated by the procedures and the credibility of the processes are discussed in view of a possible perception that the exercises may amount to little more than ‘red tape’ to justify decisions that would be taken in any case. Recommendations are made that could improve the EIA process in Antarctica.

The tenth successive annual UN session on the ‘Question of Antarctica’ took place at the close of 1992. The UN First Committee considered the topic during the week following the close of the Seventeenth Antarctic Treaty Consultative Meeting held at Venice. The passage of yet another resolution critical of the Antarctic Treaty System (ATS) suggested that little had changed as compared to previous sessions. However, during 1992, UN reports and discussions displayed evidence of a growing acknowledgement of a range of ‘positive’ developments on the part of the ATS, most notably the benefits accruing from the Protocol on Environmental Protection's designation of Antarctica as ‘a natural reserve, devoted to peace and science’ in which mining is prohibited. Significantly, both critics and the German spokesman for the Antarctic Treaty parties (ATPs) — individual ATPs still refused to participate in either the UN discussions or vote because of their belief that the UN has no meaningful role to play in the affairs of a region subject to a valid international legal regime—expressed satisfaction with the concerted approach towards Antarctica embodied in Agenda 21 of the UN Conference on Environment and Development (UNCED), which met at Rio de Janeiro in June 1992. As a result, ATPs agreed to ensure that research products were freely available to the international community. In December 1992 the adoption of UN resolution A47/57 reaffirmed the continuing divide between ATPs and other members of the international community regarding the management of Antarctica, even if the UNCED–type formula offers one route back to consensus when the UN takes up the topic again at the close of 1993.

This article examines the content and ramifications of an Australian Parliamentary Committee's Report into the application of Australian law in the Australian Antarctic Territory (AAT). The Report's main findings suggest that Australian law should be more vigorously applied in Antarctica, and that current practices with regard to the operation and enforcement of Australian law are perceived as damaging to Australian sovereignty. This is particularly the case in the context of the virtual non-application of law to all foreign nationals within the AAT, to an extent far beyond the categories of persons exempted by Article VIII of the Antarctic Treaty. The article also discusses the possible ramifications and difficulties of giving effect to the Report's findings. Particular stress is placed upon the impact of asserting a 200-nautical-mile fishing or exclusive economic zone in the waters off the AAT, as well as the logistic difficulties that may become apparent if Australian sovereignty is more actively asserted. In this context, brief consideration is given to the Report's recommendations relating to the Antarctic environment and tourism within the AAT.

Within the stable political context of the Antarctic Treaty regime, science has flourished, achieving considerable prominence and an increasing global relevance. Issues such as stratospheric ozone depletion and enhanced ultraviolet effects, environmental and climatic archive from ice cores, detection of anthropogenic pollution, study of global climate change (such as the carbon cycle and sea level), and analysis of unique collections of meteorites have attracted and focused unprecedented international attention on Antarctica. In the future, major challenges will continue to emerge in Antarctic science, driven by conceptual breakthroughs, innovative field research, and rapidly developing technology. Today's fashionable topics such as global wanning, biodiversity, thecarbon pump, and ozone loss may soon fade. What will replace them remains uncertain. The study of the coupling of presently diverse whole-earth systems appears a possibility: the biogeochemical coupling of landmasses, oceans, and ice geared to the study and provision of new food resources, to meet the demands of a world population in exponential growth, will feature considerably in the next century and involve much Antarctic research. Future science will develop against a backdrop of heightening external pressures: (1) the competing demands from the AntarcticTreaty System, including environmental concerns and possible operating restrictions, and the requirement to provide expert opinion from specialised research, (2) increasing problems of the coordination of an expanding and diverse scientific community, (3) the high cost and level of sophistication of modern research, and (4) accountability, particularly in respect of quality scientific results. Within each of these areas national programmes will assess and determine priorities for the future, which will severely test existing systems for collaboration, logistics sharing, and financial underpinning. Attention will need to be directed at a critical evaluation of the international mechanisms and frameworks for establishing the details of the Antarctic scientific agenda, and its meshing with discipline-based research in general.

A set of simple criteria for visual assessment of the effects of low-intensity fieldwork in ice-free areas of Antarctica was developed. These criteria were tested by using them to examine the impact of soil science investigations, both immediately and some time after disturbance, at Marble Point and at Cape Evans, on the shores of McMurdo Sound, Antarctica. The use of these criteria showed that for some types of impacts there had been a marked recovery of the surface with time, ranging from 22 months to 30 years. This was apparently due to repeated freeze and thaw of the soil surface and, to a lesser extent, to the influence of wind, which had partly or completely obliterated some of the earlier disturbances. More durable features remained, while deeper surface impressions, such as old soil inspection pits and vehicle tracks, showed little recovery after more than 30 years. Some biological colonisation of areas disturbed 30 years previously was occurring.

The history of the struggle for aboriginal self-government in Canada is reviewed, leading to the signing of the Model Self-Government Agreement for aboriginal First Nations in the Yukon Territory. The contents and unique features of the Model Agreement are discussed, and some conclusions on its implications for future responsible government (provincial status) for the Yukon Territory are drawn.

Epontic and benthic amphipods (Onisimus litoralis, Onisimus juveniles, Gammarus setosus, Anonyx nugax, and A. makarovi) and a pelagic mysid (Mysis oculatus) were collected under ice at Little Cornwallis Island, Northwest Territories, Canada. They were exposed, on site, to dissolved zinc and lead to determine lethal concentrations (LC50s). Incidental information was obtained on salinity and temperature tolerance. Subsequent testing of a temperate amphipod and oyster larvae exposed to the two metals provided comparative data to augment a literature review. The Arctic invertebrates were surprisingly insensitive under all test conditions. The implications for Arctic developments, particularly those involving near-shore, point-source discharges, are discussed and recommendations are made for effectively expanding a presently depauperate Arctic marine toxicity database.

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.
