North Greenland ice islands
Authors: Higgins A. K. 
Published: October 2009

AbstractLarge tabular icebergs derived from the glaciers which drain the north fringe of Greenland's Inland Iceoccur in many North Greenland fjords. Many have undulating surface topography resembling that of the ice islands calved from Ellesmere Island ice shelves. Semi-permanent sea ice in North Greenland fjords often prevents the escape of bergs, except in exceptional summers several decades apart, when the fjord ice melts completely and some bergs may reach the Arctic Ocean. Other possible sources for ice islands are small ice shelves and local glaciers along the north coast of Greenland.
Polar winters; chronic deprivation or transient hibernation?
Authors: Taylor A. J. W. 
Published: October 2009

AbstractWintering in the Antarctic has long been known to have at best a lethargic effect and at worst an occasional psychopathological effect. A review of journal entries, laboratory studies, independent observations, clinical reports and specific experimental projects shows some discrepancies about the type of impairment reported. The suggestion is that the results from various data gathering domains should be integrated, rather than offset against each other, and that climatic severity data be obtained. Then a fresh attempt should be made to resolve the matter by developing techniques for monitoring the customary levels of performance of subjects instead of those from specific testing sessions. Present indications are that wintering produces a hibernating effect — a generalised lowering of sensory/motor reactions that is appropriate for the geographical and psycho-sociological circumstances.
Diamond Jenness's archaeological investigations on Barter Island, Alaska
Authors: Jenness Stuart E. 
Published: October 2009

AbstractIn June and July 1914 DiamondJenness.amember of Stefansson's Canadian Arctic Expedition 1913–18, excavated 103 archaeological features in three abandoned native villages originally inhabited 400 to 550 years ago on Barter Island and nearby Arey Island, northern Alaska. His notes, diagrams, and some 3300 specimens for long remained unstudied. Recently they have been shown to provide much of the available information on the prehistoric occupation of the western Beaufort Sea coast.
Environmental factors affecting 17th–19th century whaling in the Greenland Sea
Authors: Sanger Chesley W. 
Published: October 2009

AbstractCommercial pelagic whaling of the 17th–19th centuries in the Greenland Sea was heavily influenced by environmental factors. Much of the fishery took place along a constantly shifting ice-edge, variations in which stamped a unique character on each season's operation. Environmental conditions required expert interpretation, both to procure paying cargoes of whale oil and bone and to survive hazards posed by sea, wind and ice. Detailed knowledge of currents, temperatures and winds enhanced greatly the chance that a master would have a successful voyage.
Sealing and sealing methods in the Bay of Bothnia, 1551–70
Authors: Kvist Roger 
Published: October 2009

AbstractSeals were hunted in the Bay of Bothnia during the 16th century in four areas — inshore open water, fast ice, ice edge, and pack ice — with methods appropriate for each area. Inshore open water sealing involved netting and some seining, exclusively for ringed seals. On fast ice the techniques used were stalking, den-hunting, and breathing hole-hunting, again for ringed seals. Grey and ringed seals were hunted on the ice edge. Provincial tax returns have provided information on methods used by sealers from different parishes in the Bay of Bothnia area. Catching techniques, tools, prey species, numbers of crews, hunting seasons, catch figures and annual yields are discussed.
The Alaska Eskimo Whaling Commission and other cooperative marine mammal management organizations in northern Alaska
Authors: Huntington Henry P. 
Published: October 2009

AbstractThe formation of the Alaska Eskimo Whaling Commission (AEWC) in 1977 was the first time that Native Alaskans had organized themselves to protect a specific hunting interest. The AEWC's success and prominence has led to the formation of other user-based management regimes for marine mammals in northern Alaska. This paper begins with a description of the creation and development of the AEWC as it fought the ban by the International Whaling Commission (IWC) on bowhead whaling and gained management authority for the Eskimo harvest. Then, three other regimes are examined, each of which focuses on a marine mammal species in northern Alaska. These are the Eskimo Walrus Commission, the Alaska and Inuvialuit Beluga Whale Committee, and the Agreement on Polar Bears in the Southern Beaufort Sea between the Inuvialuit Game Council and the North Slope Borough Fish and Game Management Committee. These regimes face the challenge of avoiding a management crisis rather than overcoming one. Without the incentive of a threat to end hunting, these regimes have not had the sense of direction that has enabled the AEWC to achieve its success. However, they have contributed to the management of certain species of wildlife, and are capable of contributing a great deal more.
Characteristics of vegetation phenology over the Alaskan landscape using AVHRR time-series data
Authors: Markon Carl J. , Fleming Michael D. , Binnian Emily F. 
Published: October 2009

AbstractAdvanced Very High Resolution Radiometer (AVHRR) satellite data were acquired and composited into twice-a-month periods from 1 May 1991 to 15 October 1991 in order to map vegetation characteristics of the Alaskan landscape. Unique spatial and temporal qualities of the AVHRR data provide information that leads to a better understanding of regional biophysical characteristics of vegetation communities and patterns. These data provided synoptic views of the landscape and depicted phenological diversity, temporal vegetation phenology (green-up, peak of green, and senescence), photosynthetic activity, and regional landscape patterns. Products generated from the data included a phenological class map, phenological composite maps (onset, peak, and duration), and photosynthetic activity maps (mean and maximum greenness). The time-series data provide opportunities to study phenological processes at small landscape scales over time periods of weeks, months, and years. Regional patterns identified on some of the maps are unique to specific areas; others correspond to biophysical or ecoregional boundaries. The data provide new insights to landscape processes, ecology, and landscape physiognomy that allow scientists to look at landscapes in ways that were previously difficult to achieve.
Detection of polar stratospheric clouds over Antarctica using AVHRR images obtained at Palmer Station during August 1992
Authors: Garcia Oswaldo , Pagan Kathy L. , Foschi Patricia G. , Gaines Steven E. , Hipskind R. Stephen 
Published: October 2009

AbstractFour case studies are presented that focus on a joint analysis of AVHRR images with other independently obtained data sets to identify examples of both optically thick and thin polar stratospheric clouds (PSCs) over Antarctica. Optically thick PSCs are shown to be readily identifiable by the temperature signatures in AVHRR channel 5 images over the Antarctic Peninsula–Weddell Sea area. A time series of optically thick PSCs as seen in satellite images obtained at Palmer Station, Antarctica, is produced and discussed. Four events are identified and discussed where the areal coverage by cold temperatures indicative of PSCs expands to cover a significant portion of the area sampled. Plans for further research are outlined.
First Doppler weather radar studies of the wintertime meteorology of interior Alaska
Authors: Fathauer Ted 
Published: October 2009

AbstractA weather surveillance radar model 88–D (WSR–88D) was installed on Pedro Dome, a hill approximately 23 km north of Fairbanks, in the late summer of 1993. The radar commenced operation in September 1993. The Fairbanks radar was the first Doppler weather radar installed in Alaska and the farthest north modern weather radar in the world. During the winter of 1993–1994 the Fairbanks radar gave meteorologists their first detailed look at the meteorology of interior Alaska. The area encompassed by the radar's field of view includes complex terrain—both large flatlands and highlands reaching more than 1 km above the valley floor.This new opportunity yielded some surprises. Foremost among them is the unanticipated complexity and small scale of meteorological processes during the winter in an Arctic region. Sequences of composite reflectivity show a consistent pattern of considerable change over time spans of 10–30 minutes, as well as large variance of reflectivity over distances of 10 km or less. The reflectivity patterns are often composed of banded structures, with small granular areas of higher echo return embedded within. The large-scale bands can be correlated to synoptic scale patterns of wind aloft, while the smaller cellular structures in the bands may be partly attributed to upslope flow over hills. However, some areas of strong radar return appear to have no relation to topography. The high stability of the airmass over Fairbanks most of the winter would appear to rule out convection. Gravity waves at the top of strong temperature inversions are a possible cause. It is presumed that other processes are at work in this scene, and they remain unexplained.
An early nineteenth century meteorological register from the eastern Canadian Arctic
Authors: Kay Paul A. 
Published: October 2009

AbstractSignificant warming in the Arctic is anticipated for doubled-CO2scenarios, 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.
The over-winter movements of a chinstrap penguin (Pygoscelis antarctica)
Authors: Wilson Rory P. , Culik Boris M. , Kosiorek Piotr , Adelung Dieter 
Published: October 2009

AbstractA single chinstrap penguin (Pygoscelis antarctica), which had moulted at the South Shetland Islands, was subsequently tracked during 120 days at sea in the austral winter using a global location system (geolocation) based on light intensity. The bird moved east along the Scotia Ridge to a point approximately 300 km west of the South Sandwich Islands and approximately 1600 km away from the colony in which it had moulted. It spent more than 60% of its time in open water north of the edge of the pack ice.
A critical review of design and use of field tent shelters in polar regions

Published: October 2009

AbstractPolar research teams often spend extended periods of time away from base stations, living and working in remote field camps of portable tents. This article reports results of a survey study conducted in 1996 of polar researchers from the United States. The study was about the design and use of portable field tents being deployed in polar areas with regard to safety, health, and well-being from the user's perspective. Preliminary analysis indicates that there existed a number of areas in design and use of the shelters that contributed to concerns of safety, health, and well-being among a considerable number of tent users. The article concludes with suggestions for designing and manufacturing portable field tents.
Adélie penguin colonies in eastern Prydz Bay: ‘biological indicators’ of exploration history and political change
Authors: Norman F.I. 
Published: October 2009

AbstractTemporally and spatially increasing information on the distribution of Adélie penguin (Pygoscelis adeliae) breeding sites is used as an index of various national activities in eastern Prydz Bay, East Antarctica. Recorded instances of such sites are used to indicate both exploration and enhanced local knowledge. While Norwegians discovered the area (1935), and revisited it (1937), reports of penguins were minimal. The 1938 Ellsworth expedition added few details and the potential of Operation Highjump (1947) photographs to delimit breeding sites was never realised. Observations by Australian expeditioners from the mid-1950s onwards, supplemented to some extent by those from the Soviet Union, increased information substantially. When Davis station was established (January 1957), at least five breeding sites were known around eastern Prydz Bay. By 1973 this had increased to 23 or 24 sites, mostly north of the Sørsdal Glacier, which had apparently acted as a barrier to land-based exploration. Data available to 1980 showed 20 sites in the Vestfold Hills, added two in the Rauer Group, and omitted some recorded earlier. Ground surveys of the Vestfold Hills (November 1973) increased known sites slightly, discounted erroneous records, and massively increased numbers of individual colonies. In 1981 an air survey recognised 24 sites in the Vestfold Hills and increased those known to 47. In approximately the same period, official Soviet records showed perhaps four sites in the Vestfold Hills and another in the Rauer Group. Early reports provided poor estimates of breeding population sizes — totals of some 130,000 (or 174,200) pairs in the Vestfold Hills in 1973 are compared with perhaps 196,600 in 1981, with another 129,000 pairs to the south. By 1983 locations of breeding sites in the Vestfold Hills were well established, and this was achieved in southern Prydz Bay following publication of 1981 survey results.Progression of information regarding breeding sites in eastern Prydz Bay was slow. Initial Australian activities were slight following acceptance of its Antarctic Territory (1933). However, a Soviet Antarctic whaling fleet, uncertainty regarding American and Soviet intentions, and the imminent International Geophysical Year increased Australian interest. A station was established, local search areas expanded, and enhanced details regarding penguin breeding sites and colonies followed. Data reviews and surveys followed increasing international interest in southern ecosystems. Improved knowledge regarding the species' local populations reflected changing political agendas. Indeed, ‘knowledge’ itself gave early support to territorial claims. Participation in international surveys became an acceptable scientific endeavour, anticipated under Treaty agreements and promoted by associated organisations. In such fora, surveys and monitoring are expected, although not necessarily furthering the strength of existing claims.
The UN and Antarctica, 1999: the continuation of consensus
Authors: Beck Peter J. 
Published: October 2009

AbstractIn 1999 the United Nations, acting in accordance with the 1996 resolution A51/56, discussed the ‘Question of Antarctica’ again. The UN, having taken up the topic on an annual basis in 1983, is currently placing it upon the First Committee's agenda every three years. The next reference will be in 2002. In 1999 the UN First Committee discussions, guided by a report produced by the UN Secretary-General (UNSG) updating members on recent Antarctic developments, indicated that disagreements still remain about the management of Antarctica. Meanwhile, members adopted another consensus resolution, A54/45, which largely replicated the wording of its 1996 predecessor, most notably in requesting the UNSG to produce another report to guide the next UN discussion scheduled for 2002. Earlier in 1999, the Lima Declaration, adopted by the Antarctic Treaty Parties in May, highlighted the view that the ATS, although linking up increasingly with UN organisations like the United Nations Environment Program, continues to offer the way forward for Antarctica in the twenty-first century.
William Robertson's account of Benjamin Leigh Smith's second expedition to Franz Josef Land in Eira
Authors: Cromack Tim , Riffenburgh Beau 
Published: October 2009

AbstractFollowing his return from participating in Benjamin Leigh Smith's expedition that wintered at Cape Flora, Northbrook Island, Franz Josef Land, in 1881–82, William Robertson, the chief engineer on the barque Eira, wrote a brief account of the expedition. Robertson's manuscript emphasises the hunting of walrus prior to reaching Franz Josef Land, the sinking of the ship, the enforced wintering, and the successful retreat of the party by open boat to Novaya Zemlya. The original of the manuscript reproduced here, which is one of only a few first-person accounts known to exist, is held by Robertson's descendants. It has not previously been published.
Antarctica in the Australian imagination
Authors: Leane Elizabeth , Pfennigwerth Stephanie 
Published: October 2009

AbstractAntarctica and Australia share a geographical marginality, a commonality that has produced and continues to reinforce historical and political ties between the two continents. Given this close relationship, surprisingly few fulllength novels set in or concerned with the Antarctic have been produced by Australian authors. Until 1990, two latenineteenth- century Utopias, and two novels by Thomas Keneally, were (to our knowledge) the sole representatives of this category. The last decade, however, has seen an upsurge of interest in Antarctica, and a corresponding increase in fictional response. Keneally's novels are ‘literary,’ but these more recent novels cover the gamut of popular genres: science fiction, action-thriller, and romance. Furthermore, they indicate a change in the perception of Antarctica and its place within international relations. Whereas Keneally is primarily concerned with the psychology of the explorer from the ‘Heroic Age,’ these younger Australian writers are interested in contemporary political, social, and environmental issues surrounding the continent. Literary critics have hitherto said little about textual representations of Antarctica; this paper opens a space for analysis of ‘Antarctic fiction,’ and explores the changing nature of Australian-Antarctic relations as represented by Australian writers.
Klarius Mikkelsen's landing site: some further notes on the 1935 Norwegian visit to the Vestfold Hills, East Antarctica
Authors: Norman F.I. , Gibson J.A.E. , Jones R.T. , Burgess J.S. 
Published: October 2009

AbstractFurther details regarding the landing made by Klarius Mikkelsen in the Tryne Islands, Vestfold Hills, East Antarctica, are given, being derived mainly from newspaper accounts made by Leif S0rsdal. All involved in the landing on 20 February 1935 have been identified, details of material left in the depot under the raised flag are given, and more extended information relating to the voyage to and from the site and the area generally are presented. Some comparison is made between Sørsdal's accounts and others. While the national importance of the landing was commented on, only S0rsdal apparently realised (but did not state) the insular nature of the site. Recent observations at the site suggest that its location is 68°22′38.22″S, 78°24′50.10″E, rather than that previously stated; bracing of the flagpole itself has been modified at some stage since its erection. Finally, some discussion is made regarding on-going questions relating to the accepted time on board ship, and possible consequences of errors.
The history of Granite House and the western geological party of Scott's Terra Nova expedition
Authors: Schroeter B. , Green T.G.A. , Seppelt R.D. 
Published: October 2009

ABSTRACTIn summer 1911—1912, during Robert Falcon Scott's Terra Nova expedition (1910–1913) a field party of four men led by the geologist Griffith Taylor surveyed the coast and hinterland of Victoria Land, Antarctica. During their stay at Cape Geology (77°00'S, 162°35'E), Granite Harbour, the members of the ‘western geological party’ built Granite House, a rock shelter used as a kitchen. The field party finished its work in the Granite Harbour region in the second week of January 1912, but heavy sea ice prevented Terra Nova from reaching the prearranged meeting point at the entrance to the bay. Faced with the possibility of being trapped for the winter, the party left Granite Harbour and travelled overland back toward the winter quarters on Ross Island. One month later the party was picked up by Terra Nova and was returned safely to Cape Evans. During an expedition to Granite Harbour in January-February 1992, the authors discovered an 80-year-old note left by the field party in a cigarette tin in the vicinity of Granite House. Dated 14 January 1912, the note was written by Taylor to Lieutenant H.L.L. Pennell, the skipper of Terra Nova, to let him know that the party had left for Cape Roberts. Granite House is a significant relic of the ‘heroic era’ and merits protection.
Tourists in Antarctica: numbers and trends
Authors: Enzenbacher Debra J. 
Published: October 2009

AbstractApproximately 39 000 tourists have visited Antarctica since 1957; numbers peryearare provided. Abrief history of sea and airborne tourism in Antarctica reveals past and current trends. The formation of the International Association of Antarctica Tour Operators and its role in the self-regulated tourism industry in Antarctica are considered, together with the implications of recently-promulgated Antarctic Treaty Recommendation XVI-13. The number of tourists visiting Antarctica is shown to exceed the combined number of scientists and support personnel from all National Antarctic Programs. It is concluded that the ATS provides a suitable framework within which to develop measures to protect Antarctica from tourist activity. However, regulations developed must be based on hard data on the size and impact of the industry to be effectively implemented.
American sealers, the United States Navy, and the Falklands 1830–32
Authors: Gough Barry M. 
Published: October 2009

ABSTRACTBy the early 1830s, American sealers expected free access to the waters and harbours of the Falkland Islands, an active rule over which had not been recognized by the United States. The US government, in the form of President Andrew Jackson and the State Department, adhered to a policy of freedom of the seas, and therefore backed the rights of American sealers to unrestricted access in the South Atlantic. After three sealing ships were impounded by the Argentinian authorities in the Falklands in 1831, the US Navy sloop Lexington, under the command of Captain Silas Duncan, destroyed the island group's capital at Puerto Soledad, and, with it, the Argentine military defences. The State Department informed the Argentine govermcnt that it had no claims, historic or actual, to the Falklands. The American policy of not recognizing the Argentine claims, which continued for half a century, did not interfere with British designs. In 1832–33 the British government issued orders for the Admiralty to send a warship to re-establish British control of the Falklands.
