Identification and assessment of contaminated sites at Casey Station, Wilkes Land, Antarctica
Authors: Deprez Patrick P. , Arens Michael , Locher Helen 
Published: October 2009

AbstractIn December 1993 a study of contaminated sites at Casey Station, Wilkes Land, Antarctica, was undertaken. The preliminary assessment of these contaminated sites is presented here. A register of contaminated sites for Casey Station was developed, based on a survey of past Antarctic expeditioners, relevant literature, and in-house reports relating to site usage and history. On this basis a sampling strategy was devised for the highest priority, potentially contaminated sites at Casey Station. Samples were collected from the refuse disposal site (tip site) at Thala Valley and the mechanical workshop/powerhouse areas of ‘Old’ Casey. The results indicated that copper, lead, and zinc were leaching from the tip site into adjacent Brown Bay, with ‘hot spots’ of high petroleum hydrocarbon levels. The mechanical workshop/powerhouse area was also shown to be contaminated with petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and metals such as copper, lead, and zinc. Several recommendations were made, including the removal of rubbish mixed with soil at the bottom end of Thala Valley in such a manner as to prevent any further release of contaminants, with subsequent site monitoring to verify effective removal of contaminants to acceptable environmental levels. It was also recommended that further investigations be carried out on the ecosystem of Brown Bay, the large fuel spill site, the upper and lower fuel-storage areas, and the area around the incinerator. There is scope for monitoring the natural breakdown and migration of contaminants at the mechanical workshop/powerhouse site. This should include studies on bioremediation of hydrocarbon-contaminated soils. Mechanisms for arresting surface migration should be investigated in those sites identified. In addition to meeting some of the international obligations of the Protocol on Environmental Protection to the Antarctic Treaty, this work also contributes towards the development of an approach to assessment and management of contaminated sites that is uniquely adapted to the Antarctic environment and could be applied at other Antarctic stations. to the assessment and management of contaminated sites that is uniquely adapted to the Antarctic environment. This approach could be utilised for site assessments at other Antarctic stations.
Components of the energy balance of the ground surface and their effect on the thermics of the substrata of the vegetation oasis at Henryk Arctowski Station, King George Island, South Shetland Islands
Authors: Prosek P. , Janouch M. , Láska K. 
Published: October 2009

AbstractThis article presents the results of measurements of the components of ground-surface energy balance (radiation balance, sensible heat flux, latent heat flux, and ground heat flux) taken during the 1994/95 summer season at Poland's Henryk Arctowski Station, King George Island, South Shetland Islands (62°09'42”S, 58°28'10”W). This was the first time that these complex measurements had been taken in the central part of the South Shetlands archipelago. The results are evaluated at the level of daily and seasonal fluctuations. The consequences of energy balance on the temperature conditions of the soil substrata are highlighted. The verification of the degree of influence of a subset of energy-balance components on soil temperature allowed analysis of the relationships among soil temperature, radiation balance, and sensible heat flux. This analysis leads to the conclusion that there is a rapid reaction of the soil temperature to the radiation balance and sensible heat flux to a depth of 5 cm. The boundary atmosphere and soil substrate represent the basic components of the ecotops of the Antarctic vegetation oasis, so these results are interpreted in pedological or botanical studies in the search for environmental influences on the vegetation.
Ten myths about the preservation of historic sites in Antarctica and some implications for Mawson's huts at Cape Denison
Authors: Hughes Janet 
Published: October 2009

AbstractA review of popular writing on the subject of preservation of historic sites in Antarctica, including buildings, graves, and artefacts, has revealed many misconceptions about the existence and cause of deterioration problems. These myths include the belief that the artefacts inside the Ross Dependency huts are in a near perfect state of preservation and that there is no corrosion in Antarctica because of the dry cold. Further examination, however, shows these views to be incorrect. These and other misconceptions are classified into three groups: (1) misunderstanding or denial of deterioration processes in Antarctic conditions; (2) simplistic assumptions about how historic buildings should be conserved in Antarctica; and (3) inappropriate comparisons between dissimilar sites.There has been considerable debate in Australia and New Zealand about how historic Antarctic buildings should be preserved. Proposed preservation methods have covered a wide range from dismantling and repatriation to a museum, re-cladding with new timber, insertion of vapour barriers inside walls to exclude ice ingress, covering buildings with a dome, and, at the other end of the spectrum of views, minimal intervention. The preservation of artefacts has also been an issue, particularly concerning whether artefacts can be effectively preserved in Antarctica or whether it is necessary to treat and store them at museums outside Antarctica. It is important to encourage consideration of all appropriate means of preservation, but it is particularly important that the causes of deterioration are understood (that is, correct diagnosis) before prescribing treatment.
The use of permafrost for the storage of oil and oil products and the burial of toxic industrial wastes in the Arctic

Published: October 2009

AbstractExperience with using permafrost for disposal of various toxic industrialwaste products and for storage of oils and petroleum products shows that underground disposal is preferable in terms of ecology and economy. However, account must be taken of possible interaction (heat, mechanical, chemical, and physico-chemical) of the buried material with the cryogenic environment and theassociated specific processes. A study of the main types of interaction of water-soluble and water-insoluble materials with frozen soil and ice permits tentative recommendations for safe storage of these materials in the Arctic.
A composite gazetteer of Antarctica
Authors: Cervellati Roberto , Ramorino Chiara , Sievers Jörn , Thomson Janet , Clarke Drew 
Published: October 2009

AbstractPublication of the Composite gazetteer of Antarctica by the SCAR Working Group on Geodesy and Geographic Information is a major milestone in the evolution of Antarctic toponymy. It has taken six years to produce, and contains 21,552 names representing 16,563 geographic features, sourced from 20 national Antarctic gazetteers and one international agency. The Gazetteer has been designed to avoid any value judgement regarding precedence or form of the various place-names. The contents of the two volumes are described, and the results of an analysis of the names data are presented. It is noted that 476 geographic features have two or more completely different names, whereas 3377 features have multiple names due to translation or transliteration. The limited progress towards development of toponymic guidelines for the Antarctic is described, along with plans for further development of the Gazetteer. An immediate benefit of the publication is that national Antarctic geographic names authorities will now be able to avoid approving new names for geographic features that are already named.
Screening Antarctica: Britain, the Falkland Islands Dependencies Survey, andScott of the Antarctic(1948)
Authors: Dodds Klaus J. 
Published: October 2009

AbstractThis paper explores Ealing Studios' cinematic production about Robert Falcon Scott and theTerra Novaexpedition, released to British audiences in 1948. Under the title ofScott of the Antarctic, the film recreated the tragic failure of the expedition on its return from the South Pole. The race to the South Pole had ended with victory for Roald Amundsen and post-colonial Norway. Three decades later, Britain again found itself involved in an intense territorial competition with two post-colonial states, Argentina and Chile. In the midst of decolonisation, the postwar government under Prime Minister Clement Attlee was engaged in a ‘cold war’ in Antarctica. The Falkland Islands Dependencies Survey (FIDS) had been created in order to protect sovereignty claims to the Antarctic Peninsula. While some attention has been given to the cultural significance ofScott of the Antarctic, there has been little geopolitical commentary on this film. As an empty space devoid of indigenous populations, Antarctica was invitingly incomplete. Produced with the co-operation of the Scott Polar Research Institute and FIDS, this film depicted a failed imperial project at a time when Britain desperately needed scientific practices such as mapping to consolidate territorial sovereignty. The paper explores the actual filming process along with the verdicts of contemporary critics in order to make a critical appraisal of Britain's changing role in Antarctica. It is sobering to note that while FIDS was supporting the filmScott of the Antarctic, Argentina was attempting to indoctrinate a new generation of schoolchildren about the realities of the Argentine Antarctic sector.
The Gloucester balloon: a communication from Franklin?
Authors: Ross W. Gillies 
Published: October 2009

AbstractOn 5 October 1851 a balloon was found near Gloucester, England, bearing a message from one of Sir John Franklin's two ships, last seen by Europeans six years before. The Admiralty responded swiftly and investigated the circumstances for several days before announcing that the message was a fake. During their inquiries no news appeared in the press. When newspapers at last published the story, most of them called the episode a hoax, although their accounts differed from each other and from the facts in many details. The Admiralty's brief announcement late in the day on 11 October gave the impression that the incident had been trivial, but in fact they had taken it very seriously. The author suggests that the hoax was carried out with an authentic balloon made for Admiralty expeditions to the Arctic, inflated with hydrogen or coal gas.
A nutritional analysis of the food rations Martin Frobisher's second expedition, 1577
Authors: Heidenreich Conrad E. , Heidenreich Nancy L. 
Published: October 2009

AbstractA list of the provisions for the second expedition led by Martin Frobisher was produced on 26 March 1577, for 115 men and 18 months. These plans contain an extraordinarily detailed food procurement list: the quantity of each food, the cost of each item, and how the rations were to be allocated. The subject of this paper is a nutritional analysis of the rations on this list. It is assumed that the March list is simply an 18-month version of what was put in place for the eventual seven-month expedition.The individual foods for the expedition were grouped into four basic meal plans, rotated throughout the journey at four ‘meat days’ and three ‘fast days’ per week. Since the amount of each food allocated per person per day was indicated, the quantities of each were able to be converted into modern measures, based on foods thought to be near equivalents to those in Frobisher's time, and the caloric and nutrient intake calculated. The results show a fairly monotonous diet of about 4000 calories on fast days to 5000 calories on meat days. Except for a virtual absence of vitamin C, the diet seems nutritionally adequate over short runs. Inadequacies could occur quickly if some foodstuffs went bad, or if members of the crew were depleted of crucial nutrients, such as ascorbic acid, before the voyage began. On longer journeys this diet would have been inadequate, as it is doubtful if beer (29% of the calories) or butter and cheese (most of the vitamin A) could have lasted for more than six months. An examination of 18 Arctic voyages between Frobisher's first (1576) and that of James (1631–1632) demonstrates that they had similar foodstuffs on board, and that few suffered appreciable dietary problems unless they were gone for more than six months.
The representations of the Swedish Antarctic Expedition, 1901–03
Authors: Lewander Lisbeth 
Published: October 2009

AbstractOn 16 October 1901 Otto Nordenskjöld departed from Sweden for Antarctica. According to most accounts published during the twentieth century, the Swedish Antarctic Expedition of 1901–03 planned and executed a substantial scientific programme, and made heroic efforts to overcome the adversity faced. This article investigates whether these descriptions are accurate and complete by examining both the long-established reports of Nordenskjöld's expedition and numerous rarely used primary sources, such as diaries and letters. In comparing these primary sources with narratives from various expedition members, competing versions of aspects of the expedition appear. This article particularly focuses on reports concerning sealing and whaling, and on the representation of the human frailties of the expedition members.

AbstractIn a joint Nordic effort, a high-quality climate data set for the Nordic Arctic is established. The data set consists of monthly values from 20 stations in Greenland, Iceland, the Faeroes, and the Norwegian Arctic. The data set is made available on the web. Ten climate elements are included, and most of the series covers the period 1890–2000. The data series illustrate the large climatic contrasts in the Nordic Arctic, and demonstrate that parts of the region have experienced substantial climate variations during the last century. Despite increasing temperatures during recent decades, the present temperature level is still lower than in the 1930s and 1950s in large parts of the region. The pattern of long-term precipitation variations is more complicated, but in parts of the region the annual precipitation has increased substantially. At Svalbard Airport and Bjørnøya the annual precipitation has increased by more than 2.5% per decade during the twentieth century.Variations in atmospheric circulation can account for most of the long-term positive trend in precipitation in the Norwegian Arctic, and also for the positive temperature trend from the 1960s. The positive temperature trend before 1930 and the negative trend during the following decades, are, however, not accounted for by the circulation models.
Temperature and precipitation in Svalbard 1912–2050: measurements and scenarios
Authors: Hanssen-Bauer I. 
Published: October 2009

AbstractTemperature and precipitation series from Svalbard for the period 1912–2000 were analysed. There was a statistically significant warming from 1912 to the 1930s, a cooling from the 1930s to the 1960s and a warming from the 1960s to present. There was a positive trend in the annual mean temperature during the period 1912–2000, but it was not statistically significant. Spring was the only season when a statistically significant warming was found. For precipitation, statistically significant positive trends during the period 1912–2000 were found on an annual basis and in all seasons except winter. Empirical downscaling was applied on the results from a global climate model to produce scenarios for monthly temperature and precipitation in Svalbard. The 2 m temperature was applied as predictor for temperature. For precipitation, a combination of temperature and sea-level pressure was used. The temperature scenario indicates a warming of about 1°C per decade in winter, and 0.3°C per decade in summer from 1961 to 2050. The projected increase in annual mean temperature is about five times the average warming rate from 1912 to present, and highly significant. The precipitation scenario also indicates that precipitation will increase significantly until 2050. The maximum increase was projected in spring precipitation; however, the trends in seasonal precipitation are quite uncertain.
Clay minerals in response to the Pleistocene climate change on the Yermak Plateau, Arctic Ocean (ODP, Site 911)
Authors: Ruikka Mattiina , Strand Kari 
Published: October 2009

AbstractThe Arctic plays an important role in controlling the Earth's climate and ocean circulation. Studies of past climate conditions in high latitudes are important to understand this role more precisely. Clay mineralogy of sediments was detected to be comparative with cyclic changes in climatic conditions during the past 0.8 Ma in the northernmost Atlantic-Arctic gateway (Ocean Drilling Program, Site 911). Clay minerals are transported by sea ice, icebergs, glaciofluvially, or by ocean currents. Smectite is assumed to be transported predominantly during interglacial periods. Its content decreases from about 0.4 Ma to the present, which may indicate lesser eroded smectite in the provenance area, assumed to be mostly in the Laptev Sea. Illite is due to erosion from Svalbard during glacial periods, and shows a negative correlation with smectite. Chlorite is not a good climate indicator because of its high frequency in the northern regions. Zemlya Frantsa-Iosifa (Franz Josef Land) is the most likely source area of kaolinite and the output seems to have slightly increased from 0.5 to 0.4 Ma. The correlation of kaolinite and chlorite means coincidental sedimentation. Kaolinite and chlorite are negatively correlated with illite, which indicates transportation during the more open ocean conditions that prevailed between repeated Pleistocene glaciations.
Charles Swithinbank: glaciologist
Authors: Cruwys Liz , Riffenburgh Beau 
Published: October 2009

AbstractThis is the second in a series of biographies entitled ‘Children of the Golden Age,’ the purpose of which is to describe the background and contributions of significant living figures in polar research who began their scientific careers in the years following World War II. Born on 17 November 1926 in Burma, Charles Winthrop Molesworth Swithinbank attended Bryanston School in Dorset before joining the Royal Navy in 1944. He read geography at the University of Oxford and was named assistant glaciologist for the Norwegian-British-Swedish Expedition (1949–52). After completing his DPhil, he joined the Scott Polar Research Institute, where he studied ice distribution in the Northwest Passage. Moving to the University of Michigan (1959–63), he led three expeditions to the Ross Ice Shelf before becoming the first British exchange scientist with the Soviet Antarctic Expedition (1963–65). Returning to the Scott Polar Research Institute, he developed a glaciological programme that led to his appointment as chief glaciologist of the British Antarctic Survey. He became head of the Earth Sciences Division in 1974, a post he held until his retirement in 1986. Swithinbank's contributions to Antarctic science include studies of the deformation, flow, and thickness of glaciers and the interpretation of satellite imagery. He served as president of the International Glaciological Society (1981–84) and has received a number of honours and awards.
‘The faithfulness of our dealings’: the correspondence between George Simpson and Ferdinand von Wrangell, 1838–48
Authors: Stone Ian R. 
Published: October 2009

AbstractBy an agreement in 1839, the Hudson's Bay Company and the Russian American Company established a framework for co-operation in their activities in Alaska and adjacent areas of Canada that lasted until the 1860s. The signatories to the agreement were George Simpson and Ferdinand von Wrangell. These men were prominent in the management of the co-operation and this was facilitated by their mutual trust and friendship. An examination of their correspondence affords insights into business methods in a cross-cultural environment in the mid-nineteenth century, and into the extent to which their personal relations influenced major decisions in economics and politics with regard to the areas of activity of both companies.
Life on the ice: understanding the codes of a changing environment
Authors: Aporta Claudio 
Published: October 2009

ABSTRACTThis article is concerned with the knowledge of sea ice as developed and transmitted by the Inuit of Igloolik (Nunavut, Canada). The information on which this article is based was obtained from travelling, observation, and interviewing carried out from October 2000 to May 2001 in Igloolik, as well as several existing interviews from the Igloolik Oral History Project database. Inuit knowledge of sea ice reveals a deep understanding of the complex relationships between ice, currents, the Moon, and the winds, as well as a holistic approach to knowledge where classification based on a western scientific approach becomes difficult, if not counter-productive. Through detailed knowledge of ice topography, sea ice becomes a familiar territory for the Inuit of Igloolik, and, through the understanding of the ‘codes’ of the moving ice, its changing nature becomes predictable. This article does not pretend to give a full account of a system of knowledge the understanding of which requires a lifetime of practice and observation. However, it describes some of its elements and offer some insights regarding this complex aspect of Inuit Qaujimajatuqangit (Inuit knowledge, also known as IQ).
Whaling records and changes in Antarctic sea ice: consistency with historical records
Authors: de la Mare William K. 
Published: October 2009

AbstractA claim that there are substantial discrepancies between direct observations of the Antarctic sea-ice edge and the implicit sea-ice edge derived from whaling records is rebutted. The claimeddiscrepancies are shown to arise largely from comparing the two types of information from different dates. A date-corrected comparison shows generally good agreement between the southernmost limit of whaling and the most comprehensive of the early monthly ice charts of Antarctica. The remaining apparent discrepancies are accounted for either by very limited data or the complex nature of the ice edge in the region of the Weddell ice tongue. Correlation of the southernmost limits of whaling with direct observations of the ice edge provides the most powerful calibration of the relationship between them
