Uncontrolled scaling for furs and oil began on South Georgia about 1786 and continued sporadically until the early 20th century. From 1909 onward legislation covered licensed killing of male elephant seals Mirounga leonina. This provided for a successful oiling industry that lasted almost 60 years, operated by whalers primarily in early spring before the whaling season began. Biological research ensured that quotas in the last decade remained within the carrying capacity of the stocks. High-grade seal oil enhanced revenues from whaling, providing overall 16% of the volume and 19% of the value of total annual catches, with much higher proportions in some seasons. The seal oil industry did not long survive the demise of whaling on South Georgia, finally ending in 1968.

Recent decisions of the Supreme Court of Canada, the Constitution Act 1982, and the establishment of the Office of Native Claims, would seem to have assured the rapid settlement of outstanding issues regarding aboriginal rights and native title to lands. More recently, the seeming abandonment by government of political and negotiated resolution of these issues has left litigation as the remaining recourse for native groups to protect their interests. The courts, however, have become increasingly demanding in terms of what must be proven in order to make a successful case at law. It is predicted that the costs and technical difficulties of providing such proofs will limit the number of rights cases before the courts, and the chances of success for those that are mounted.

Reindeer milk is used by native peoples throughout the Soviet North. This article describes how different groups use, or have in the past used, the milk in raw and processed form. After summarizing the properties of reindeer milk, it outlines a neglected chapter in the history of domesticated animals: the attempt in the 1930s to set up a commercial reindeer dairy industry in the USSR. Lastly, it analyzes the decline of reindeer milking among peoples of the Soviet north in this century.

The cash revenues and imputed incomes from country food harvests were calculated from interviews with eight full-time hunting and ten wage-earning Inuit for 1984 at Holman, Northwest Territories. Using a substitution value of Can$10.56/kg ($4.79/lb) for country food harvests, the combined income (cash + imputed food value) of the two groups was very similar. Full-time hunters produced country food at $1.01/kg ($0.46/lb). while wage earners spent $5.7 I/kg ($2.59/lb) on their harvest. Full-time hunters harvested surpluses of food which would feed another fourpeople outside their immediate family. Wage earners ended the year with almost twice the cash balance of full-time hunters, whose main monetary revenuecomes from guiding trophy hunters. The precarious cash economy of the full-time hunters who provide a significant part of the food for the village should be a subject of concern and attention when considering the future well-being of the northern economy.

In the austral summer 1986–87, the 75th anniversary of Amundsen's conquest of the South Pole, a sledging party of four from a private expedition, 90° South, set out to retrace his route. This was the culmination of five years of preparations, in which sufficient international support was raised to enable the expedition to reach Antarctica and operate independently, using its own ship, MV Aurora… The expedition's Twin Otter aircraft, flying from New Zealand, staged a unique refuelling operation on an iceberg within the pack ice 160 km from the Balleny Islands. Establishing a temporary base at Bay of Whales, Ross Ice Shelf, on 5 December 1986, the expedition used its aircraft to set up supply depots 220 km apart along the route to the pole. The sledging party with two teams of Greenland huskies crossed the ice shelf and ascended the Axel Heiberg Glacier to the polar plateau, reaching their fourth depot in 86°S in late January. Some 400 km short of the Pole, lack of time compelled the party to return to rendezvous with the ship. Glaciological investigations included the formation of icebergs from the Ross Ice Shelf, and collection of ground truth data to help in evaluating remote sensing data. The team also set up a commemorative plaque close to Amundsen' s cairn on Mount Betty.

Born in 1867 and trained as a doctor, Jean-Baptiste Charcot gave up a fashionable medical practice to become, in his mid-thirties, France's leading polar explorer. His two major expeditions to the peninsular sector of Antarctica and the Bellingshausen Sea (1903–05, 1908–10) resulted in many new discoveries of land and established his reputation as a leader in the fields of scientific oceanography, research and survey. After service in World War I he continued polar work with a series of ten summer expeditions to the Arctic (1926–36), in which many young explorers were trained. Lost with his ship Pourquoi Pas? in a storm off Iceland in 1936, Charcot is remembered for qualities of leadership and scientific integrity which inspire the current generation of French polar scientists.

Activity patterns of native people in the Northwest Territories include a complex mixture of employment in the modern economy, full-time or part-time engagement in traditional pursuits, and leisure. This study identifies characteristics of participants in each activity which assist in interpreting the allocation of time among employment in the modern economy, the pursuit of traditional activities, and leisure. Three hypotheses—traditionalist, modernist and culturalist — were identified from current literature and tested statistically, using data collected in interviews held with 11,164 NWT residents in 1984. The hypotheses were: (1) engagement in the traditional sector is preferred to holding a job in the modem economy; thus, wage employment primarily facilitates pursuit of traditional activities; (2) engagement in the modern economy is preferred; those unable to work in it turn to traditional activities, which are easier to enter; (3) the traditional sector is an arena in which a cultural heritage can be maintained, a preferred sustenance obtained, or where one can demonstrate his prowess apart from any material gain that might be realized. The data do not unequivocally support any of the hypotheses, but this study suggests an alternative approach to the interpretation of activity patterns, based upon an analysis of individual preference functions.

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.

Speed/distance meters were deployed on adeliée, gentoo and chinstrap penguins Pygoscelis adeliae, P. papua and P. antarctica, breeding near Anvers Island, Antarctica. Underwater speeds and distances travelled were interspecifically very similar (means of ca. 7–8 km h-1 and 15–45 km, respectively). These results are compared with published data on penguin behaviour at sea obtained by using identical methodology. A simple model, based on penguin activity at sea data, is developed to derive range limits for penguins. Derived range limits are substantially lower than previous estimates but accord well with distributional data obtained by transects.

Stomachs of 171 vertebrates (two species offish, eight of birds and twoof seals) from Hornsund, Svalbard, were collected between 7 September and 5 October 1984. Arctic cod Boreogadus saida and the amphipod Pamthemisto libellula were the main prey species of black guillemots Cepphus grylle, little auks Alle alle, puffins Fratercula arctica, Brunnich's guillemots Uria lomvia, kittiwakes Rissa tridactyla and ringed seals Phoca hispida. Fulmars Fulmarus glacialis preyed mainly on the squid Gonatusfabricii and the polychaete Nereis irrorata. Eiders Somateria mollissima preyed mainly on bivalves and on the amphipod Gammarellus homari. G. homari and Gammarus oceanicus were the most important prey species of striped snailfish Liparis liparis, while shorthorn sculpin Myoxocephalus scorpius mainly preyed upon G. homari and Anonyx sarsi. Glaucous gulls LOTUS hyperboreus took many different prey including birds and tundra plants. Only one bearded seal Erignathus barbatus stomach with content was available for this study.

In June 1988, at the final session of the Fourth Special Antarctic Treaty Consultative Meeting in Wellington, New Zealand, the Convention on the Regulation of Antarctic Mineral Resource Activities (CRAMRA) was adopted, bringing to a successful conclusion six years of negotiations. Christopher Beeby, chairman of the discussions, presented the convention as the most important political development affecting Antarctica since the 1959 treaty, especially as it established the ability of the Antarctic Treaty System to reach an internal accommodation even upon matters raising serious political, legal, environmental and other issues. There remain uncertainties regarding the future development of the Antarctic minerals question; for example, when will the minerals convention and the proposed institutional framework come into effect, will its ratification encourage mining, can the fragile Antarctic environment be adequately protected against mining, how will certain key terms and concepts be defined, and will the regime's operation bring latent tensions to the surface? It is also difficult to predict how other governments will react to the convention, in the light of recent UN resolutions on Antarctica. The convention is perceived within the Antarctic Treaty system as a significant development, but it will be some time before a considered evaluation of the Antarctic Minerals Regime can be conducted.

Contemporary dimensions of a conflict over the political powers of Alaska Natives and their relationship to the larger society were set by the Alaska Native Claims Settlement Act (ANCSA) of 1971. This granted land and money to Alaska Natives, established corporations to use these assets, and ensured that the land and the corporations would remain under Native control until at least 1991. Under 1987 amendments to ANCSA, Congress extended these special protections indefinitely. Leaders of the tribal government movement in Alaska tried unsuccessfully to use the amendments to gain increased political power and federal recognition of Native tribes and tribal governments. They were opposed by federal authorities, Alaska's US senators, the State of Alaska, non-Native political interest groups, and Native leaders of the ANCSA corporations. Although stalled in this instance, the drive toward tribal government, or ‘sovereignty’, in Alaska remains a viable political movement. It is part of a continuing evolution of Native politics which in its modern form began with land claims and now includes a much broader concern for political claims of sovereignty, or inherent self-governing powers. In pursuing this course, however, tribal leaders will need to focus more on specific requirements for Native security and welfare than on general claims of sovereignty, and avoid direct confrontations with powerful opponents.

This paper identifies improvements which can be made to management plans for environmentally sensitive areas in Antarctica, drawing attention to (a) the characteristics of the antarctic environmental planning hierarchy which set it apart from planning and management systems applied to most other regions of the world, (b) the effectiveness of plans covering Sites of Special Scientific Interest (SSSI), (c) practical measures to improve site management (especially co-operatively), and (d) ways of integrating site management with broader conservation goals.

Large tabular icebergs derived from the glaciers which drain the north fringe of Greenland's Inland Iceoccur in many North Greenland fjords. Many have undulating surface topography resembling that of the ice islands calved from Ellesmere Island ice shelves. Semi-permanent sea ice in North Greenland fjords often prevents the escape of bergs, except in exceptional summers several decades apart, when the fjord ice melts completely and some bergs may reach the Arctic Ocean. Other possible sources for ice islands are small ice shelves and local glaciers along the north coast of Greenland.

This article outlines the Marginal Ice Zone Experiments (MIZEX), which began in 1983, and summarizes research investigations in Fram Strait during the most recent MIZEX of March and April 1987, involving members of the Scott Polar Research Institute (SPRI). An important field of investigation was ambient noise in the ice-edge region and the physical processes which produce it.

Many northern regions of North America have come to rely heavily on extraction of non-renewable resources for their income, at the expense of traditional land-based economies. Such extraction leads to boom and bust income, destructive to long-term planning for sustainable development. Natural resource trust funds, as exemplified in Alberta, Alaska, Montana, Wyoming and New Mexico, would help to provide the stability that is currently lacking in Yukon and the Northwest Territories. Maintained by setting aside part of the current income from non-renewable resources, they yield capital and income that can be used to encourage the mixed, self-sustaining local communities appropriate for the North.

The original Alaska Native Claims Settlement Act, passed in 1971, gave Alaska Native corporations fee simple title to 18 million hectares of Alaskan land. Within a few years of its passage, however, Alaska Natives grew concerned that this land would be lost through mismanagement of the corporations or forced into development by property taxation. Because large numbers of Alaska Natives depend upon subsistence hunting and fishing, the loss of the land, or its use for activities incompatible with subsistence, could have been devastating. Amendments of 1987 (PL 100–241) protect Native corporation land by placing all undeveloped land in a land bank and allowing for the formation of ‘Settlement Trusts“. More importantly, Congress recognized that the Native subsistence economy and culture are significant factors in the management of Native lands.

The Eveny of northeastern Siberia live mainly by reindeer herding. Though this is highly economical, since collectivization it has progressively separated the nomadic herders from their families in the centralized villages. This leads to a low birth-rate and the estrangement of children from herding. Under percstroika, labour is being reorganized into a system of contracts. Though the aim is to increase efficiency, this may also allow families to live and work together again. However, logistic problems, such as schooling, remain. These developments are taking place against a background of increasing ethnic consciousness and open public debate on policy.

Eight species of vascular plants were previously known from subantarctic Heard Island. Three additional species, Montia fontana, Ranunculus biternatus and Poa annua, were discovered during the 1986 austral summer. Details of their habitat and known distribution on the island, and their possible means of arrival, are discussed.
