The relics of polar exploration are treasured in the museums of a multitude of nations. In Australia, the focus of most such collections is Sir Douglas Mawson and his expeditions to Antarctica in 1911–14 and 1929–31. The nature of these collections divides into the two large categories of scientific specimens and expedition relics. The latter are spread among Australian and other museums in a distribution that speaks of fascination with the exotic and heroic aspects of the Australasian Antarctic Expedition and the geopolitical ramifications of the British, Australian and New Zealand Antarctic Research Expedition. The specimens, by contrast, have not been treated well, and although thoroughly documented, may be close to losing their integrity as scientific resources. Both types of material merit the renewed attention of their museum-keepers as resources on the history of Antarctica.

During the last two decades the archipelago of Svalbard has evolved as a focal point for tourism and scientific research in the Arctic. In 1995 the Norwegian authorities inaugurated a management plan in order to conserve Svalbard and to minimise environmental degradation resulting from increased anthropogenic activity. However, the potential for accelerated modification of the tundra, as a result of field camps, was not addressed. Parameters, such as percentage vegetation cover, soil compaction, and soil infiltration rate were measured before and after a four-week period of field-camp activity, under controlled conditions, during July 1997. The study site was located near Ny-Ålesund, Kongsfjorden, Spitsbergen. Statistical analysis showed that where no significant differences in the parameters were recorded at the control site, the presence of a field camp did cause a significant impact on the Arctic heath tundra surface. For example, mean soil compaction, increased from 1.16 kg cm-2 to 2.57 kg cm-2. The use of good practice procedures, such as moving tents regularly and utilising a groundsheet, did not prevent an impact on the environment. Key parameters at the main study sites were reassessed in July 1999, revealing that no significant recovery from the impact caused in 1997 had occurred. An established campsite at Ny-Ålesund was also studied in 1997, and the results support the findings of the main survey: a significant difference recorded for the parameters measured at the campsite, compared to negligible or no changes at the control site. In order to achieve a sustainable tourism and science-based community in Svalbard, i t is proposed that the existing management plan be expanded to incorporate a set of guidelines for wilderness camping, with the aim of mitigating the impact of field camps on the tundra.

Experience 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.

Temporally 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.

In the polar desert of the high Arctic, underlain by continuous permafrost and commonly snow-covered for much of the year, the paucity of plant growth might seem unsurprising. Although low temperatures and lack of moisture exert a strong influence on plant life and can greatly diminish the rate at which plants can grow, these are nevertheless not the only factors involved. Lack of mineral nutrients, in an environment where chemical weathering is inhibited, may play an even greater part. In consequence, where nutrient-rich decaying animal bones are present, it is not uncommon to find growing upon them a luxuriant vegetation of mosses and vascular plants, together with less spectacular algae and lichens, which show up in striking contrast to the barren ground around them. These microhabitats, in turn, carry their own fauna of invertebrates. This paper examines, in detail, one such specimen and its flora and fauna — a 2000-year-old shed caribou antler from the ground surface at Cape Herschel, Ellesmere Island, 78°N.
