In 1947 knowledge of Heard Island was confined to a rough mapping compiled by nineteenth-century sealers, and the results of four scientific expeditions that had briefly investigated the Atlas Cove area. Exploration continued in two distinct periods between 1947 and 1971. In the first period the Australian National Antarctic Research Expeditions (ANARE) built a scientific station at Atlas Cove in 1947, and occupied it continuously until 1955 as an ‘A Class’ meteorological station, a seismic and magnetic observatory, and a base for other scientific studies and for exploration of the island. In the second period four summer expeditions and one wintering expedition worked on the island between 1963 and 1971. The summer expeditions were an ANARE expedition in 1963, an Australian private expedition (The South Indian Ocean Expedition to Heard Island) in 1965, and ANARE expeditions in 1969 and 1971 associated with United States and French expeditions. A United States expedition wintered in 1969. There were no further expeditions until 1980. The years 1947–1971 saw many achievements. Expedition members recorded seven years of synoptic meteorological observations and four years of seismic and magnetic observations. They developed empirical techniques of work, travel, and survival that shaped the collective character of ANARE and were later applied in Antarctica. Despite difficult terrain and consistently bad weather, and the accidental deaths of two men in 1952, unsupported field parties of two or three men travelling on foot explored and mapped in detail the heavily glaciated island, and documented its topography, geology, glaciology and biology. They made three overland circuits of the island, the first ascent of Big Ben (2745 m), and the first recorded landing on the nearby McDonald Islands. Expedition members bred and trained dog teams for later use in Antarctica. They reported the commencement and subsequent progress of massive glacier retreat caused by regional warming, and of the island's colonisation by king penguins (Aptenodytes patagonicus) and antarctic fur seals (Arctocephalus gazella). They also reported measurements of glacier flow and thickness, the palaeomagnetism of Heard Island rocks, behavioural and population studies of southern giant petrels (Macronectes giganteus) and other birds, studies of southern elephant seals (Mirounga leonina) and leopard seals (Hydrurga leptonyx), and the cold stress and acclimatisation experienced by humans working in the island's wet-cold climate. In addition, Heard Island served as a testing ground for men, equipment, scientific programmes, huskies, general administration, and logistics, without which Mawson station could not have been established as successfully as it was in 1954. The American wintering expedition and the French summer expedition contributed to major international geodetic and geophysical investigations. In sum, the expeditions between 1947 and 1971 added much to our knowledge of Heard Island, and they laid down a solid foundation for the work of later expeditions.

Since the end of the Cold War, cooperative and region-building endeavours involving Arctic governments and peoples have flourished. These efforts have been rooted in a desire to pursue northern sustainable development and in assertions about the shared experiences and values of Arctic states and peoples. In this paper, a case study is presented concerning a Canadian development project designed to promote Canadian sustainable economic development models to indigenous and non-indigenous leaders and bureaucrats in the Russian north. In their efforts to move knowledge across northern borders, the Canadian project team relied clearly upon two central discourses of the Arctic region-building process: a common Arctic space and the shared pursuit of sustainable development. Drawing upon over thirty qualitative interviews and a year of participant observation at project events, the aim of this article is to map the currency and reach of these Arctic regional discourses at a more ‘local’ level amongst the Russian and Canadian Arctic residents involved in the project. The continuing debate during this development project over what Arctic regionalism and sustainable development mean in practice calls into question a key assertion of contemporary region-building rhetoric, the assumption or hopeful injunction that not only is a regional landscape or environment shared but that values and experiences are, or will come to be, shared as well.

In 2002 and 2003, studies were made of the breeding phenology, nesting success, nesting density, and rates of nest predation of ruddy turnstones (Arenaria interpres) at East Bay, Southampton Island, Nunavut, Canada. Previous data from East Bay were used to compare nesting chronology and nest success across years. Bird banding data were used to examine migration routes and rates of return. In all years, ruddy turnstones initiated nests within 7 days of arrival at the study area. The median date of incubation onset was the same in 2002 and 2003, despite different spring snow conditions. Snow remained later in the season in 2003 and the overall range of incubation onset was greater than in 2002. Ruddy turnstones at East Bay nested at high densities and in semi-colonial groups with a significantly aggregated distribution. In both years, nest success was low, predation was high, and lemmings were scarce. These data (and data from earlier East Bay studies) support the ‘alternative prey hypothesis’. Resighting rates of breeding adults between 2002 and 2003 were also low. Individuals banded at East Bay were resighted at Delaware Bay on the Atlantic coast of the United States, the Caribbean Islands, and in southern Brazil. This study increases our knowledge of this understudied species about which there is conservation concern.

The Norwegian Henrik Johan Bull managed the Antarctic expedition that penetrated the Ross Sea in 1895 and made a landing at Cape Adare, the first confirmed landing on the Antarctic mainland. Bull had attempted to fund the voyage in Melbourne where he had lived since the late 1880s. At that time, Melbourne's learned societies, through their Antarctic Exploration Committee (AEC), were also making strenuous attempts to launch an expedition. The two parties had contact but the differences in their aims resulted in little cooperation. The AEC plans of a joint commercial/scientific expedition with Dundee or Norwegian whalers, and then a joint scientific expedition under Adolf Erik Nordenskiöld, foundered due to lack of funds. The plans to include a scientist, nominated by the learned societies, in Bull's expedition also failed. Instead, Carsten Egeberg Borchgrevink joined Bull's expedition as an ordinary seaman and an occasional scientist. He used this experience to realise his plans to winter on Antarctica. Both Bull and the AEC were important in developing interest in Antarctic exploration and commerce.

Since the 1970s, a number of writers have endorsed the belief that Dr John Richardson very probably committed discreditable, and possibly even criminal, acts during the first Franklin expedition (1819–1822). These acts, they allege, were concealed from the public by Franklin and Richardson, who inserted a fabricated account into Franklin's 1823 narrative. This paper examines the evidence and arguments put forward by the originator of this theory, the historian Richard Glover. It concludes that Glover was motivated primarily by a desire to vindicate the good name of another explorer, Samuel Hearne. Richardson had suggested that Hearne's narrative was not an entirely reliable account of his travels, and in Glover's view, these remarks had seriously damaged Hearne's reputation. Glover therefore sought to characterise Richardson as a deceitful man of exceptionally poor judgement, upon whose claims no reliance could be placed. Later writers, engaged in a re-evaluation of Britain's imperial activities in the Canadian north, have accepted and expanded on Glover's theories. However, an examination of the primary sources cited by Glover and others demonstrates that there is no solid basis for the revisionist version of the 1819–1822 expedition.

Between 2003 and 2006, the Centre for Topographic Information in Sherbrooke (CTI), Québec, under the Canadian Space Agency (CSA) Government Related Initiatives Programme (GRIP), conducted a project (Cartonord project) aimed at new base mapping at a scale of 1:50,000 for unmapped areas of northern Canada using earth observation data.

Some additional details of the construction of ‘Franklin's cairn’ and ‘Franklin's cenotaph’ on Beechey Island, Nunavut, Canada are presented.

John Hugh Mather was a member of the crew of Terra Nova, the vessel of R. F. Scott's expedition of 1910–1913. After World War I, he participated in the allied campaign against the Bolsheviks in Arctic Russia and achieved considerable distinction in that area of operations.

A case of polar bear infanticide and cannibalism is reported from Phippsøya, Svalbard. In this instance, a cub of some 7 months was killed by an adult male bear, which was in poor condition, in the close proximity of the mother, which was also in poor condition. It seems probable that the attack was made for nutritional gain.

The partially snow-covered wreck of specially-modified Arctic variant of the Tupolev TB-3 four-engine bomber was located at Buhkta Teplits [Teplits Bay], Ostrov Rudol'fa [Rudolf Island] in Zemlya Frantsa-Iosifa [Franz Josef Land]. From data gathered, the wreck was subsequently identified as TB-3 (ANT-6) No. 210. This aircraft was piloted by Boris Chukhnovsky during a failed search for another TB-3 (ANT-6), No. 209, which had been lost in August 1937 during an attempt to fly from Moscow over the north pole to the United States. The Teplits TB-3 (ANT-6) wreck represents both the primary aeronautical archaeology of the triumphs and disasters of the Soviet Union's air expeditions to the pole in 1937–1938 and, at 81°47.5'N, is the northernmost aircraft wreck yet identified.

New communications equipment has been installed at Port Lockroy with the aim of rendering more efficient the booking system for visits by cruise ships and other vessels.
