Significant warming in the Arctic is anticipated for doubled-CO2 scenarios, but temperatures in the eastern Canadian Arctic have not yet exhibited that trend in the last few decades. The spatial juxtaposition of the winter station in 1822–1823 of William Edward Parry's Northwest Passage expedition with the modern Igloolik Research Centre of the Science Institute of the Northwest Territories affords an opportunity for historical reconstruction and comparison. Parry's data are internally consistent. The association of colder temperatures with westerly and northerly winds, and wanner temperatures with easterly and southerly winds, is statistically significant. Temperatures are not exactly comparable between the two time periods because of differences in instrumentation, exposure, and frequency of readings. Nevertheless, in 1822–1823, November and December appear to have been cold and January to March mild compared to modern experience. Anomalously, winds were more frequently northerly (and less frequently westerly) in the latter months than in recent observations. Parry recorded two warm episodes in mid-winter, but, overall, it appears that the winter of 1822–1823 was not outside the range of modern experience.

Glacial Crooked Lake was an ice-dammed impoundment in Vestfold Hills, East Antarctica, that had a volume of (250 ± 45) × 10 m. The impoundment is inferred to have existed during deglaciation following the Late Holocene Chelnok Advance of Sørsdal Glacier. The dam released water incrementally, allowing the formation of four major series of shorelines with a maximum height of 24 m above the current lake level of 22 m asl. Water from Glacial Crooked Lake overflowed into Watts Lake downstream, allowing saltwater there to mix, dilute, and be transported to the sea via Ellis Rapids. In this way water in Watts Lake became fresh, and alluvial fans consisting of cobbles and boulders formed below Crooked Lake and Ellis Rapids.

The range of the barren-ground caribou in Canada includes approximately 700 000 square miles [1 812 993 sq km]: north from the forests of Manitoba and Saskatchewan to the Arctic Ocean and west from Hudson Bay to Alaska. Much of that vast expanse of stunted forests and tundra remained virtually unmapped until the ingress of the aeroplane in the 1930's.

In January 2007, MS Golden Princess, carrying 2425 passengers and a crew of approximately 1100, became the largest ship to sail Antarctic waters within the northern limit of pack ice. This note describes the ship and its itinerary, discusses aspects of the cruise, and comments on the use of large cruise liners in Antarctic waters.

At Cape Adare, there are three wooden historic huts in varying condition. Two are the first permanent structures erected in Antarctica for human habitation and were occupied in 1899 by the British Antarctic Expedition (1898–1900) led by C.E. Borchgrevink. The third hut was built in 1911 by the northern party of R.F. Scott's British Antarctic Expedition (1910–13) led by V.L.A. Campbell. Previous research has focused on the unusual wind regime at Ridley Beach, Cape Adare, with the use of an environmental wind tunnel to support field observations, and on the sequence of destruction by wind of the 1911 hut. The present paper focuses on the weathering of timber at some historic huts in Antarctica and presents observations and data collected on three visits to Cape Adare spanning 21 years. The results indicate that over 23% of the timber has been eroded from exposed board ends on one corner of Borchgrevink's ‘stores hut’ and further damage to the huts is being caused by wind blown sand and pebbles which, at two meters above the ground surface, can attain a velocity of 29–203 km/hr−1. This has in places, resulted in severe degradation of the timber.

Further information is presented relating to a sledge discovered on Byers Peninsula, Livingston Island, South Shetland Islands in 2007.

This is the first in a series of biographies entitled ‘Children of the Golden Age’, the purpose of which is to describe the background and contributions of a number of significant living figures in polar research, all of whom began their scientific careers and earned their Antarctic spurs in the years following World War II. Bernard Stonehouse was born in Hull on 1 May 1926. Joining the Royal Navy in 1944, he trained as a pilot, and in 1946–50 served as meteorologist, second pilot, dog-sledger, and ultimately biologist with the Falkland Islands Dependencies Survey, mainly from Base E, Stonington Island, Antarctic Peninsula. His first biological investigation was a winter study of breeding emperor penguins. Returning to Britain in 1950 he read zoology and geology at University College, London. Doctoral research at the Edward Grey Institute of Field Ornithology and Merton College, Oxford, involved an 18-month field study of king penguins on South Georgia. Between 1960 and 1968, as senior lecturer, later reader, in zoology, at University of Canterbury, Christchurch, New Zealand, he continued Antarctic and sub-Antarctic research in McMurdo Sound and on the New Zealand southern islands. A Commonwealth Research Fellowship at the University of British Columbia, 1970–71, gave him opportunities for research in the Yukon. After developing undergraduate and postgraduate studies in environmental science at the University of Bradford, 1972–83, he joined the Scott Polar Research Institute as editor of Polar Record, thereafter forming the Institute's Polar Ecology and Management Group, and heading a long-term study on the ecological impacts of polar tourism. At SPRI he continues to combine the two factors that have always played an important part in his life: working in polar regions and communicating with the general public on issues of biology, the environment, and conservation.

The introduction of the ‘western diet’ marked a decline in omega–3 fatty acids rich foods and a concurrent increase in saturated and omega–6 fatty acids that persists today. Historically, circumpolar people have had a low incidence of obesity, diabetes and cardiovascular disease and this has been largely attributed to polyphenolic compounds and omega–3 fatty acids offered from subsistence foods. In this report, we studied sled dogs as an Arctic sentinel species for monitoring the effect of a changing diet on lipid profiles along the Yukon River. Subsistence fed village sled dogs along the Yukon River, maintained largely on salmon were compared with a control kennel maintained on commercial food. Profiles showed higher levels for long chain omega–3 fatty acids in village subsistence fed dogs compared to control dogs and an opposite trend for omega–6 fatty acids, establishing baseline levels for follow up studies. A comparison with data for previously published mercury levels from the same cohort of dogs revealed a positive correlation with alpha–linolenic fatty acid and a negative correlation with linoleic fatty acid. Food and nutritional security is a concern in the Arctic as the impacts of climate change and transport of contaminants become obvious. This study supports not only the nutritional value of a subsistence diet but also the utility of sled dogs as a sentinel for human dietary change.

Captain Robert Falcon Scott has been attacked in recent decades because his Terra Nova expedition (1910–1913) had to rely on substandard Siberian ponies. Certain commentators have argued that this was Scott's fault, but the available evidence indicates that blame should rest with the buyer Cecil Meares. Additionally, archive evidence indicates that Scott specifically requested Captain Lawrence Oates to travel to Siberia to assist Meares in 1910, and that Oates refused Scott's request.

This note considers the decision by the UK government to rename the southern portion of the Antarctic Peninsula - Queen Elizabeth Land. Named in honour of the UK Head of State, it was intended to be a ‘gift’ recognising her Diamond Jubilee. However, the 169,000 square mile territory in question is counter-claimed by Argentina and Chile. The circumstances surrounding this declaration, in December 2012, reveals both the contested politics of Antarctic place naming, and a growing willingness of the UK government to strengthen its ‘strategic presence’ in the Antarctic and wider South Atlantic/Falkland Islands region. This naming event provoked Argentina to issue a formal protest note to the UK Ambassador to Argentina.

This article investigates how in the Soviet Arctic researchers and indigenous communities searched and understood the mammoth before and during the Cold War. Based on a vast number of published and unpublished sources as well as interviews with scholars and reindeer herders, this article demonstrates that the mammoth, as a paleontological find fusing together features of extinct and extant species, plays an in-between role among various environmental epistemologies. The author refers to moments of interactions among these different actors as “environmental encounters”, which comprise and engage with the physical, political, social and cultural environments of the Arctic. These encounters shape the temporal stabilisations of knowledge which enable the mammoth to live its post-extinct life. This article combines approaches from environmental history and anthropology, history of science and indigenous studies showing the social vitality of a “fossil object”.

The Antarctic Treaty, which entered into force on 23 June 1961, has been widely welcomed. It marked the beginning of a new era in Antarctic politics and provided a basis for the further development of scientific co-operation. Article IX provides for the holding of meetings (generally known as “Consultative Meetings”) for the purposes of exchanging information, of consultation and of formulating measures in furtherance of the principles and objectives of the Treaty, including the “preservation and conservation of living resources in Antarctica”. The four Consultative Meetings held since the entry into force of the Treaty have adopted over twenty Recommendations on the conservation of wildlife, and in the short space of six years the Antarctic has been made subject to conservation measures which are more comprehensive than those in any other major region in the world. The seed sown in the Treaty has borne fruit in a remarkably short time. It is the purpose of this article to describe and comment, from the legal standpoint, upon these internationally agreed conservation measures.

Samples from 73 pieces of non-structural driftwood on Heard Island (53°06′S, 73°30′E) were identified to genus or species. Thirty-one belonged to South American species of Nothofagus. The remainder, consisting mostly of conifers especially Picea and Larix, probably came from ships' cargoes. The assemblage is similar to those reported, from smaller samples, on other southern islands. Other items of flotsam, including fishing buoys and drift-cards, are also reported from Heard Island. The significance of driftwood transport from South America to the island in accounting for long-distance dispersal of terrestrial and intertidal organisms is discussed.
