By Article 2(e) of the 1951 Treaty of Peace, Japan renounced ‘all claim to any right or title to or interest in connection with any part of the Antarctic area.’ This paper traces the process by which Australian diplomacy ensured the inclusion of such a provision in the Treaty and assesses the contemporary significance of the article. While in the unlikely event of the breakdown of the Antarctic Treaty System, Japan would be legally entitled to make a territorial claim on the basis of activities undertaken between the conclusion of the Peace Treaty and the coming into force of the Antarctic Treaty, such a claim would likely be weak. It is more probable that the Japanese government would assert that, just as Japan had had no rights to renounce in Antarctica, neither had any of the Antarctic claimants complied adequately with the provisions in international law for territorial acquisition.

During January and February 1997, two separate surveys of the birds and seals of the South Sandwich Islands archipelago were made, with further data obtained from the northern islands during February 1998. Together, these surveys provide the most recent and accurate estimates of breeding populations of most species, their distributions, and their habitat. Observations were made (1) from a small vessel operating close inshore, which surveyed approximately 92% of the archipelago's coastline, in addition to making shore counts at selected locations; (2) during a six-week shorebased field camp on Candlemas Island; and (3) opportunistically during helicopter-supported landings and airborne operations over all islands in the archipelago. The surveys recorded 16 species of breeding birds, including the first confirmation of breeding by black-bellied storm petrels (Fregetta tropica) and Antarctic terns (Sterna vittata), the second record of incubating king penguins (Aptenodytes patagonicus), and the location of many previously unrecorded seabird breeding sites. The population of chinstrap penguins (Pygoscelis antarctica), at approximately 1.5 x 10 pairs is considerably less than the estimate of 5 x 10 pairs currently in use, and represents about 30% of the world population. Populations of chinstrap penguins, Antarctic fulmars (Fulmarus glacialoides), cape petrels (Daption capense), and snow petrels (Pagodroma nivea) in the South Sandwich Islands are of global significance. Five species of seals were recorded. At the time of the surveys, only Antarctic fur seals (Arctocephalus gazella) were confirmed to be breeding, and several new breeding sites were located. Pup numbers showed a small increase compared with the few earlier records, but the population has not undergone the large increases seen on South Georgia and at sites in the maritime Antarctic. The other four species recorded are considered highly likely to breed either within the archipelago or amongst pack ice that seasonally surrounds the islands.

US policy toward the Antarctic between 1939 and 1949 reflected the inability of the Department of State and other government personnel to agree on the region's relevance to national security. Washington's intent to gain worldwide prestige by promoting a harmonious settlement of the dispute over sovereignty claims complicated the international situation to an extent that necessitated a shift to the status quo moratorium proposed by Chile. The United States finally attempted to rally support for this alternative that, in turn, complicated how to exclude the USSR. Although the risk of Soviet encroachment seriously concerned US officials, it posed less immediate dangers than letting conflict escalate between Britain, Chile, and Argentina.

Survey work by the British North East Greenland Project in the Scoresby Sund fjord complex between 70 and 72°N is documented. A number of sites are identified and described, as are two contemporary Inuit playhouses at a current fishing camp. It is indicated that there are opportunities for further archaeological recording within the Scoresby Sund fjord system, although sites within the inner fjord system do not appear to be numerous. Locating them will require determined fieldwork.

The discharge in Tierney Creek from proglacial Chelnok Lake was recorded during the summer of 1987–1988. In addition, air temperature, water temperature, and radiation were recorded. Multiple linear regressions revealed that discharge could be predicted from recorded radiation and air temperature in late summer. In early summer, other factors such as wind must also be taken into account. Long-term discharge fluctuations displayed response times that decreased during the runoff season due to the opening of the meltwater channels on the ice-margin. During parts of the runoff season, flow variations were modulated by nocturnal freezing in the creek, a phenomenon still more pronounced in Onyx River in the Dry Valleys of Victoria Land. Hydrologically, Tierney Creek resembled Onyx River, but, in the Onyx, the flow pattern was more exclusively determined by low air temperatures than it was in Tierney Creek. In the Dry Valleys, streams whose lengths, gradients, and discharges are of the same magnitude as those of Tierney Creek, also display similar recession coefficients and time lags between flow peak and insolation peak.
