This article explores how climate change has recently influenced the Iñupiaq cultural identity as the people of the whales. Their traditional whaling cycle reveals strong indivisibility of music, emotions, and place based human identity. To illustrate such integrity of the Iñupiat and their culturally critical bowhead whale (Balaena mysticetus), a search was made for specific ways in which climate change influences Iñupiaq spiritual and physical ties with the whale in relation to traditional music making. Traditionally, the Iñupiat say that it is the whale who brings them music, thus no whale harvest means no music production. However, when the environment is less predictable, the homeland eroded, place based songs gone, and human-whale integrity threatened, how specifically are these changes manifested in the Iñupiat-whale relationship? Providing detailed descriptions of 2005–2006 nalukataq (midsummer whale feasts), this article examines how contemporary Iñupiat respond to environmental changes in the emotional and cultural dimensions through their music making.

Emperor penguins Aptenodytes forsteri are endemic to Antarctica. Their breeding colonies are located in the coastal areas of the continent. The precise number of breeding locations is uncertain. This paper examines what is known about the colonies in the Australian Antarctic Territory and examines which colonies are without doubt breeding locations and which ones require further examination in order to determine their existence and status. Several colonies have not been seen since they were first reported. This begs the question of whether the reported sightings were indeed of breeding colonies. Given the extent of uncertainty with regard to the number of colonies, it is suggested that the listing of the species by the International Union for the Conservation of Nature be changed from ‘of least concern’ to ‘data deficient’.

The four polar years are used as windows for highlighting changes in the character of polar research over the past 125 years. The approach taken may be seen as one of an archaeology of knowledge. As such it fixes on four separate strata in the history of science and seeks to lay bare distinctive features in each of these. To simplify, the focus is selective, mainly presenting three types of aspect for each year. The first is the character of the instruments and research technologies employed in each, and the second is the kinds of problems tackled, while the third is the associated view or ideal of science that stands out. The latter aspect has to do with epistemology. The paper suggests that whereas work during the first International Polar Year (IPY) reflected an empirical inductivist philosophy of science, during the second IPY a mix of problem oriented, and hypothesis driven, approaches existed alongside inductivism. By the time of the International Geophysical Year (IGY) the theoretical foundations of polar research had grown stronger and much of the focus had shifted to larger scale geophysical processes. Finally, today's ambition to develop an integrated Earth system science reflects an ideal that is systemic, constructivist and predictive. Such epistemological features are evident in some of the most advanced forms of computer aided analysis of Arctic and Antarctic processes, as well as in visualisation methodologies used to interpret and present data, concepts, models and theories. This latest approach is evident in some of the planning and agenda setting documents generated under the auspices of the current IPY.

The Qajuuttap Sermia glacier system north of Johan Dahl Land, on the southern slope of the Greenland ice sheet (the inland ice), has shown continuous advancing behaviour from approximately 1940 until approximately 2000. This contrasts with neighbouring sectors of the inland ice to the west and southeast, where the ice sheet has shown a more ‘normal’ trend of recession and thinning of the margin since about 1850–1890, and that has continued throughout the last half of the 20th century. The Qajuuttap Sermia glacier system has also attracted interest for its hydropower potential, and detailed investigations were carried out in 1977–1983. This article summarises the fluctuations of the Qajuuttap Sermia glacier system, and documents the demonstrable advance of the individual glaciers of the system from the early 1940s until the early years of the present millennium. The cause of the advance seems likely to be related to variations in precipitation over the southernmost parts of the inland ice, with the highlands north of Johan Dahl Land directly influencing the passage of low pressure systems moving both northwards along the west coast and northeastwards along the east coast of Greenland.

On 1 September 1909, Dr Frederick A. Cook landed at Lerwick in the Shetland Islands and cabled the unexpected news that he had reached the North Pole on 21 April of the previous year. This article recounts the equally unexpected recovery of the original telegram drafts Cook wrote for the cables sent from Lerwick. It discusses new details they add to the historical record and confirms others that previously had no confirmation. It also verifies the authenticity of the drafts, and, based on the physical condition of the recovered documents and documentary clues, it traces what can be known of the history of these documents between the time Cook wrote them and their publication a century later, proposing how they might have been originally saved from destruction in 1909.

Enquiries by Norwegian whalers precipitated the British annexation of the Falkland Island Dependencies and the Ross Dependency. Seeking territory free of British control, Lars Christensen's Norwegian whalers claimed Bouvet Island, which the British believed was theirs. Realisation of the economic value of whaling led Leopold Amery, of the British colonial office to develop Britain's Antarctic domination policy. In pursuit of this policy, the 1926 Imperial Conference formulated a process to claim a sector of Antarctica for Australia. A.G. Price's The Winning of Australian Antarctica describes the role of the Mawson led BANZARE in this process. To gain title to Bouvet Island, the Norwegian Government, dependant on friendly relations with Britain, agreed not to claim territory listed by the Imperial Conference as of ‘special interest’ to Britain. Claims made by whalers who had mapped and named territory in the unlisted area between Kemp and Queen Mary Lands were rejected by the Norwegian prime minister. Following the 1933 Order in Council establishing the Australian Antarctic Territory, Norway raised concerns that the territory included Haakon VII Vidde (polar plateau) and the parts of Dronning (Queen) Maud Land that had been mapped and discovered by Norwegians. Price's contention that Australian Antarctica was ‘won’ is questionable.

Reindeer and caribou are terrestrial herbivores, that feed on lichens and are used for commercial and subsistence food products. Caribou are a key component of the arctic food web and the bioaccumulation of toxic contaminants, such as mercury (Hg), needs to be monitored to establish a baseline as the arctic environment is impacted by both climate change and future industrial development. A changing climate in Alaska is influencing plant species composition, fire regime, melting and flooding events, and thus, impacting Hg bioavailability in the food chain. Industrial development in Asia is also projected to increase the atmospheric global pool of Hg from increased coal combustion. Reindeer, a domesticated representative of caribou, can be used as a terrestrial biomonitor for metal exposure. In this study total mercury concentrations were measured in lichens and in hair of grazing reindeer on defined ranges across Alaska to establish a baseline for future hypothesis development and testing regarding Hg deposition. The Hg mean level for Seward Peninsula lichens on the Davis Range was 37.4 ng g−1, on the Gray Range 47.1 ng g−1, on the Kakaruk Range 42.2 ng g−1, and 41.7 ng g−1 on the Noyakuk Range. Lichen Hg levels on St. Lawrence Island was 46.6 ng g−1. Methyl mercury levels in lichens were found to be below detection levels. Reindeer grazing on these ranges had mean Hg hair levels of 14.6 ng g−1 (Davis herd), 83.4 ng g−1 (Gray herd), and 40.3 ng g−1 (Noyakuk herd). Two reindeer on St. Lawrence Island had an average of Hg of 43.0 ng g−1. Sample sizes ranged from n = 2 to n = 11. Hg mean levels in lichen on Seward Peninsula were higher than Hg means of two ranges in northern Mongolia. The Hg levels observed in this study indicate that Hg levels in Alaska are low at this time and pose no risk to the health of reindeer or human subsistence harvesters. A significant relationship between Hg in lichens on the ranges and the Hg in reindeer on those ranges has not been established. There are insufficient data on Hg levels in many areas of the north and more information is needed on location specific and time trends in Hg concentrations. Lichens and reindeer hair provide a good, non-invasive method of monitoring metal exposure changes in Alaskan ecosystems.

Potential Adélie penguin Pygoscelis adeliae breeding habitat in the Australian Antarctic Territory (AAT: 45°E–136°E, 142°E–160°E) was mapped using a geographic information system (GIS), and the literature reviewed for evidence of the mapped habitat being searched for presence or absence of breeding Adélie penguins. It is concluded that incomplete search effort is a possible source of substantial negative bias of Adélie penguin breeding abundance derived from published count data in some regions of the AAT. The extent of search effort in other regions of Antarctica could be determined using the same approach applied here, because GIS data required for mapping potential habitat are available for the entire continent. We would expect that regions with more scientific and tourist activity, such as the Antarctic Peninsula, are likely to have greater search effort than the AAT.

At the first Comité Special de l'Année Geophysique Internationale (CSAGI) Antarctic conference, held in July 1955, the opening remarks of its president, supported by a resolution proposed by the Chilean Ambassador and passed unanimously, stipulated that the meeting was not to be concerned with political matters and that its purposes were exclusively scientific. Those guidelines were not entirely successful. The Chilean resolution was itself a political move, and delegates reported that the meeting was repeatedly disturbed by further political interventions. The conference was nevertheless significant because it was the first time that representatives of eleven countries ever attended such a meeting, thus ensuring that the International Geophysical Year would mark a new phase in international relations respecting Antarctica.

The Arctic Ocean is crossing an environmental threshold from a permanently ice covered to seasonally ice free ocean during summer, with emerging geopolitical interactions of relevance to international peace and stability. In response, the Arctic Ocean Geopolitics Programme was initiated at the Scott Polar Research Institute, University of Cambridge, in September 2008 with the following objectives:

1. 1) to enhance cooperation in an international, interdisciplinary and inclusive manner among existing research teams that are focusing on Arctic Ocean geopolitics;

2. 2) to provide parliamentary, governmental, civil-society and industry audiences with objective analyses of environmental security issues and alternative responses in the Arctic Ocean; and

3. 3) to identify lessons from the Arctic Ocean regarding the governance dynamics of nation states and international spaces beyond national jurisdiction.
