Genetic variation inArmeria maritimain Iceland
Authors: Philipp Marianne 
Published: October 2009

AbstractA comparison of the population genetic structureof Armeria maritimain Iceland with an earlier study in Denmark was undertaken. Ten populations were sampled in Iceland for isozyme analysis. Most populations showed Hardy-Weinberg proportions, but a higher number than statistically expected possessed too many homozygotes. This could indicate a breakdown of the self-incompatibility system in some cases. Statistically significant differences in allelic frequencies among populations were observed but no positive correlation between genetic distance and geographic position was found. Gene diversity in Iceland was lower than in Denmark although the alleles occurring in Iceland were the same as those found in Denmark. Missing alleles were those found with lowest frequency in Denmark. It is suggested thatA. maritimain Iceland has immigrated from the southern part of the distribution post-glacially, leaving behind the rare alleles.
Defibration of wood in the expedition huts of Antarctica: an unusual deterioration process occurring in the polar environment
Authors: Blanchette Robert A. , Held Benjamin W. , Farrell Roberta L. 
Published: October 2009

AbstractSignificant deterioration to the historic expedition huts of the Ross Sea region of Antarctica has occurred during the past decades from exposure to the polar environment. One type of deterioration that has affected all of the huts is a chemical attack resulting in a defibration of wood. Wood surfaces have a rough, fuzzy appearance and consist of white to yellow-brown masses of detached fibers. The damage is commonly associated with areas where water with dissolved salts is absorbed by wood. As moisture evaporates from the wood surface, exceedingly high concentrations of salt accumulate. Chemical reactions within the wood cause a corrosive degradation on the middle lamella region of the woody cell wall (the area located between cells that cements them together) and may gradually degrade all cell-wall layers. As the deterioration progresses, cells continue to separate and the wood is converted into masses of detached and eroded wood fibers. In advanced stages of attack, the wood structure and integrity is severely compromised. This paper describes the defibration process, reports locations on Ross Island where the damage is severe, and discusses methods to control the problem. Successful preservation of these important historic structures and cultural objects depends on a more complete understanding of the unique deterioration processes underway and on implementation of effective strategies to conserve the huts.
Reindeer dairying in the Soviet Union
Authors: Fondahl Gail 
Published: October 2009

AbstractReindeer 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.
Antarctica at the UN 1988: seeking a bridge of understanding
Authors: Beck Peter J. 
Published: October 2009

ABSTRACTThe struggle between Antarctic Treaty Parties and their UN critics regarding the management of Antarctica was resumed in November 1988 when, for the sixth successive year, the United Nations discussed the 'Question of Antarctica'. This year the UN adopted two further resolutions reaffirming demands of 1987 for wider participation in the minerals negotiations, the involvement of the UN Secretary-General in Antarctic Treaty System operations, and the exclusion of South Africa from treaty meetings. The Treaty Parties seem unlikely to heed these resolutions. Reforms within the Treaty System are the most likely means of progress for the critics, althoough Australia's critique of the Minerals Convention has introduced an element of uncertainty.
Mules of the British Antarctic Expedition 1910–13
Authors: Harrowfield D. L. 
Published: October 2009

AbstractHorses were first used in Antarctica when eight Manchurian ponies provided support for Shackleton's British Antarctic Expedition (1907–09). Scott's British Antarctic ‘Terra Nova’ Expedition (1910–13) used 17 ponies during its first year, and seven Indian mules in the following season. This paper presents new information on the mules, which suffered severely from the effects of an unbalanced diet and low temperatures. They were the last horses ever used to support an Antarctic expedition. In January 1989 when the stables of Scott's hut at Cape Evans were reclad and cleared of ice by a working party from the Antarctic Heritage Trust (New Zealand Antarctic Research Programme), artefacts relating to their occupancy by Manchurian ponies and Indian mules were located.
Monitoring shipborne visitors in Antarctica: a preliminary field study
Authors: Stonehouse Bernard 
Published: October 2009

ABSTRACTDuring every austral summer since the International Geophysical Year 1957–58 several thousand scientists and support staff have worked in Antarctica. A more recent development is the annual advent of 4000–5000 tourists, who now probably outnumber expedition members in the area covered by the Antarctic Treaty System. Most tourists come by ship, visiting coastal areas of the Antarctic Peninsula and the South Orkney and South Shetland islands that arc readily accessible beween November and March: smaller numbers visit the Ross Dependency and Adelie Land sectors. This article reviews Antarctic Treaty and International Union for the Conservation of Nature and Natural Resources (IUCN) attitudes to tourism, and outlines a preliminary study of shipborne tourism between late December 1991 and March 1992 on Half Moon Island, South Shetland Islands. Within one month (January) a survey team from the Scott Polar Research Institute, University of Cambridge, recorded 14 visits by six tour ships, bringing more than 2000 tourists. In addition, attitudes and expectations of visitors were studied on five ships. Arising from this study, a programme of visitor monitoring is planned as a joint project between British, Chilean, and Argentine scientific institutions during the next five years. Objectives are to find ways of minimizing both short-term and long-term impacts of tourists and other visitors on breeding birds and other ecological communities, and to provide a factual basis for regulation under the Antarctic Treaty System.
Pesticide residues in the sediments from the lakes of Schirmacher Oasis, Antarctica
Authors: Sarkar A. , Singbal S.Y.S. , Fondekar S.P. 
Published: October 2009

AbstractConcentration levels of various organochlorine pesticides and their derivatives — namely, hexachlorocyclohexanes (HCH) and the DDT compounds pp'-DDT, op'-DDT, pp'-DDE, op'-DDE, pp'-DDD, and op'-DDD — were determined in the sediments from eight different lakes of the Schirmacher Oasis, near Dakshin Gangotri, the Indian station (70° 45'S, 11° 44'E) during the Sixth Indian scientific expedition to Antarctica (December 1986 to February 1987). Concentration levels of HCHs (α, β, γ)and t-DDT (pp'-DDT + op'-DDT + pp'-DDE + op'-DDE + pp'-DDD + op'-DDD) in sediments of these lakes were found to be in the ranges of 37.7–155 pg/gand 512.9–1131 pg/g, respectively. Among the isomers of HCH, gamma-HCH was most prominent, followed by alpha-HCH, whereas in the case of metabolites of DDT and its isomers, pp'-DDT was found to be dominant over others. However, all the other compounds of the DDT family were present in considerable amounts in all the lakes. There was no significant change in the monthly variation of the concentration levels of HCHs and DDTs in the lakes.
Spying on the Russians: Archibald Douglas and HMS Egeria at Petropavlovsk, 1877–1878
Authors: Stone Ian R. 
Published: October 2009

AbstractThe period 1877–1878 was one of tension between Britain and Russia caused by the Russo-Turkish War and the consequent threat to the route to India. The Royal Navy was deployed to deter the Russians in seas adjacent to the Balkans, but also undertook intelligence gathering missions further afield. Two of these were to Petropavlovsk in sub-Arctic Kamchatka and were undertaken by Commander A.L. Douglas in HMS Egeria. The British, with their French allies, had sustained a serious defeat there during the Crimean War and wished to ascertain the state of Russian defences should there be fresh hostilities. In the event, Douglas discovered that the Russians had abandoned Petropavlovsk as a fortified post and that there was no garrison. His reports were, therefore, negative, but included interesting information concerning Petropavlovsk in this era.
Willard Wentzel's account of the Mackenzie River
Authors: Riffenburgh Beau , Holland Clive , Davis Richard 
Published: October 2009

AbstractFollowing his return from participating in John Franklin's first overland expedition (1819–1822), Willard Wentzel, a clerk for the North West Company, produced a map of the Mackenzie River and a brief account of its geography, native peoples, and history and significance as it related to the North West Company. This map and the account, which is one of the few early descriptions of the Mackenzie River area, are held in the Royal Commonwealth Society Papers at the University of Cambridge. They have not previously been published.
Acquisition of consultative status under the Antarctic Treaty
Authors: Pannatier Serge 
Published: October 2009

AbstractUnder the regime established by the Antarctic Treaty of 1959, decision-making remains exclusively with the limited number of states that are entitled to appoint representatives to participate in Antarctic Treaty Consultative Meetings. Whereas the 12 original signatory states have a permanent right to attend these meetings, acceding states may gain consultative status only during the time they carry out substantial scientific research in the Antarctic. This paper addresses three issues: the first relates to the problems arising out of the ‘admission procedure’ adopted by the original signatory states when faced with the first application of an acceding state to become an Antarctic Treaty Consultative Party, a procedure that has been applied ever since to similar cases. The second looks at the forms of scientific research activities an acceding party ought to conduct in Antarctica in order to meet the requirements laid down in the Antarctic Treaty. The third deals more generally with the issue of limited participation in the Antarctic Treaty decision-making process, which has come under severe criticism from non-Consultative Parties and states that have not acceded to the Treaty.
British Antarctic Policy in the Early 20th Century
Authors: Beck Peter J. 
Published: October 2009

World War I has often been said to mark the end of the ‘Age of Imperialism’—the close of ‘that final surge of land hunger’ (Landes 1969) from 1880 to 1914 when much of the world's land surface, especially in Africa and the Pacific, was acquired by the major powers. Britain's large share was demonstrated by the predominance of red on pre-1914 maps, though in fact the British Empire achieved its greatest areaafter1918; ‘… including India’, reported the 1920Colonial Office List, ‘the Empire now extends over 11 million of square miles, or 91 times the area of the Mother Country’ (Mercer 1920). This study examines one specific part of British imperial policy in the immediate post-war years—one which, had it been fully implemented, would have increased the area by a further 40 per cent. In the view of L. S. Amery, Under-Secretary of State at the Colonial Office and one of Britain's leading politicians of the time, it was desirable that:… the whole of the Antarctic should ultimately be included within the British Empire, and that, while the time has not yet arrived that a claim to all the continental territories should be put forward publicly, a definite and consistent policy should be followed of extending and asserting British control with the object of ultimately making it complete.
Humpback whalesMegaptera novaeangliaeand southern right whalesEubalaena australisin Gerlache Strait, Antarctica
Authors: Stone Gregory S. , Hamner William M. 
Published: October 2009

AbstractDuring surveys conducted 2–20 April 1986 in Gerlache Strait, Antarctic Peninsula, 103 humpback whalesMegaptera novaeangliaeand eight right whalesEubalaena australiswere sighted. The right whale sightings extend the southern limit of known distribution for the species. Humpback and right whale densities were respectively 0.22 (sd 0.23) and 0.01 (sd 0.06) whales per survey mile. Highest densities for both species were recorded inside bays, rather than in the relatively open water of Gerlache Strait. Both species were feeding on Antarctic krillEuphausia superba. Twenty-three humpback and four right whales were identified individually using photographs of natural features. Also included are sighting records of 18 southern bottlenose whalesHyperoodon planifrons.
Limnology of Priyadarshani Lake, Schirmacher Oasis, Antarctica
Authors: Ingole B. S. , Parulekar A. H. 
Published: October 2009

ABSTRACTPriyadarshani, an oligotrophic lake in Schirmacher Oasis (Antarctica), was surveyed during the austral summers of 1984–85 and 1986–87 in limnological and benthic studies. Benthic microfauna included seven taxonomic groups, dominated numerically by protozoa, rotifera, nematoda, turbellaria, tardigrada, oligochaeta and mites. Faunal density was high in moss-associated sediments. A maximum water depth of 6.5 m was recorded at the centre of the lake. A thick layer (25–90 cm) of moss and algal communities covered the bottom sediments. The total volume of water was estimated to be 62 million m3 over the submerged area of 0·297 km2.
Hobart, Tasmania: Antarctic and Southern Ocean connections
Authors: Kriwoken Lorne K. , Williamson John W. 
Published: October 2009

abstractThis 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.
Environmental impact assessment in Antarctica under the Protocol on Environmental Protection
Authors: Lyons David 
Published: October 2009

ABSTRACTThe 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 career and disappearance of Hans K.E. Krüger, Arctic geologist, 1886–1930
Authors: Barr William 
Published: October 2009

ABSTRACTOn 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.
A simple visual technique for estimating the impact of fieldwork on the terrestrial environment in ice-free areas of Antarctica
Authors: Campbell I. B. , Balks M. R. , Claridge G. G. C. 
Published: October 2009

ABSTRACTA 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.
Measured properties of the Antarctic ice sheet derived from the SCAR Antarctic digital database
Authors: Fox Adrian J. , Paul A. , Cooper R. 
Published: October 2009

AbstractThe completion of the SCAR Antarctic digital database (ADD) has provided a new basis for statistical calculations for Antarctica: data-sets are available at the scale of the original source material, and generalised to 1:1,000,000, 1:3,000,000, 1:10,000,000, and 1:30,000,000. The new descriptive statistics presented are based on the ADD 1:1,000,000 data-set since this is the largest scale at which source maps provided complete cover of the coastline and ice-free areas. The statistics include the total length and proportions of coastline types and the total area of Antarctica with the proportions of its constituent feature types. The areas of the Ross and Filchner-Ronne ice shelves have also been computed. Whilst the total area of Antarctica has remained static compared with previous studies, the relative proportions of coastline types and constituent feature types within the total area show significant changes. In particular the calculated area of ice-free ground is only approximately one-seventh of that often quoted from previous studies. The changes reported result from improved mapping, reinterpretation of data, and actual changes of coastline.
Airdrops and king penguins: a potential conservation problem at sub-Antarctic Marion Island
Authors: Cooper John , Avenant Nico L. , Lafite Peter W. 
Published: October 2009

ABSTRACTEvidence for the disturbance of king penguins (Aptenodytes patagonicus) and other seabirds at sub-Antarctic islands by fixed-wing aircraft making airdrops is reviewed. Based on direct observations of panicking birds at king penguin colonies at Marion Island as Lockheed C-130 Hercules aircraft flew past, it is postulated that the incident at Macquarie Island in 1990 when many king penguins were found dead shortly after a flypast was most likely caused by panic induced by the aircraft's passage. Visits by fixed-wing aircraft to sub-Antarctic islands should be kept to a minimum and no airstrips should be built on them. Specific recommendations are given for fixed-wing aircraft visits to Marion Island, in order to reduce disturbance to king penguins and other seabirds to the absolute minimum. These recommendations should be adopted at all sub-Antarctic islands.
Standardisation of zones within specially protected and managed areas under the Antarctic Environmental Protocol
Authors: Harris Colin M. 
Published: October 2009

ABSTRACTA number of countries are revising management plans for protected areas in Antarctica so that they comply with Annex V to the Protocol on Environmental Protection to the Antarctic Treaty. Annex V allows for ‘identification of zones…in which activities are to be prohibited, restricted or managed.’ A wide range of terms are, and could be, used to meet site-specific zoning needs. If allowed to develop in an ad hoc way, a confusing and inconsistent set of zones would be likely to evolve. This could be avoided by a coordinated and pro-active approach to identifying the zones needed. Based on field observations and examination of current and proposed management plans, a simple, standardised model of five types of zone is proposed: Restricted, Scientific, Tourist, Facilities, and Historic. Their application, where needed, would meet the full range of management needs within specially protected and managed areas in Antarctica.
Sledges and sledging in polar regions
Authors: Pearson Michael 
Published: October 2009

ABSTRACTSledges have been used for millennia in Arctic and sub-Arctic regions. Until the advent of British Arctic land exploration in the nineteenth century, explorers in these regions had relied on indigenous sledges. The British, and individuals from other nations engaging in polar exploration, often faced different conditions and challenges from those that had faced indigenous peoples, and so a period of adaptation and invention began, to develop sledges that better suited the needs of European survey parties. This paper looks at the range of indigenous sledges and the development of various polar sledge types based on indigenous ski-runner, edge-runner, and toboggan styles of sledges. The development of the Nansen sledge, which became the norm in the Antarctic, is discussed, and the issues and debates involving man-hauling versus dog-hauling and the relative effectiveness of sledges and motive power as shown by recorded sledging performances are outlined.
George Phillips, Vilhjalmur Stefansson, and supplying the Canadian Arctic Expedition 1913–1918
Authors: Gough Barry M. , Greenhouse John Phillips 
Published: October 2009

ABSTRACTGeorge Phillips, the naval stores officer at Esquimalt, British Columbia, was responsible for supplying from that base the Canadian Arctic Expedition (1913–1918) led by Vilhjalmur Stefansson. In addition to arranging details of supply in conjunction with directives from his superiors, Phillips travelled with Stefansson by steamer to Nome, Alaska, beforeKarluk, the brigantine to be used by the southern division of the expedition, sailed on her ill-fated voyage. This article is based on hitherto unused documentation, including the private notebooks and personal correspondence of Phillips. It examines two issues: first, the problems of supply for the Canadian Arctic Expedition, and, second, the personal views of Phillips with respect to Stefansson and other members of the party.
