The Antarctic

Five main British Antarctic Survey stations were occupied throughout the year: Faraday and Halley (the two geophysical observatories), Signy (the main biological station), Grytviken (a multidisciplinary sub-Antarctic station and centre for the Offshore Biological Programme) and Rothera (the centre for earth sciences programmes). During the 1979 winter, routine programmes were maintained by 72 men who also made preparations for the forthcoming summer season. The two BAS ships, RRS John Biscoe and RRS Bransfield, with assistance from two Twin Otter aircraft relieved the stations, as usual, and assisted summer field workers. Valuable assistance was also given by the ice-patrol ship, HMS Endurance. John Biscoearrived in the Antarctic late in the season, having been delayed while her refit was completed. (The ship, which has been in continuous service since 1965, had undergone major repairs and modifications to ensure her continued suitability for Antarctic service and to increase her usefulness as a floating laboratory.) All stations were relieved without difficulty, but, because of this season's tight shipping schedules, Rothera was not reached by sea until the end of March 1980, although it had been relieved by air at the beginning of January. At Halley, the season was overshadowed by the death of the base commander, Miles Mosley, in an accident involving one of the aircraft. A second man was injured but made a complete recovery. At Faraday, good progress was made with the programme of modernization. Part of the main building was demolished and replaced by a new extension, and a desalination plant and new inflatable fuel tank were brought into use.

Five main British Antarctic Survey stations were occupied throughout the year. These were Faraday and Halley (the two geophysical observatories), Signy (the main biological station), Grytviken (a multi-disciplinary sub-Antarctic station and centre for the Offshore Biological Programme) and Rothera (the centre for earth sciences programmes). During the 1978 winter, routine programmes were maintained by 69 men who also made preparations for the forthcoming summer season. The two BAS ships, RRS John Biscoe and RRS Bransfield, with assistance from two Twin Otter aircraft relieved the stations, as usual, and assisted summer field workers. With the early recall of John Biscoe to undergo a major refit, invaluable support was also given by HMS Endurance, especially in the Trinity Peninsula area. Apart from Rothera, relief was completed by the end of January 1979 and, in marked contrast to some years, Halley was reached without difficulty. Persistent sea ice late into the season in the southern part of the west coast of the Antarctic Peninsula meant that Rothera could not be reached by Bransfield until mid-February. However, the season saw the completion of the new Rothera station, some major rebuilding at Faraday (originally constructed in 1954) and the installation of a new ionospherics laboratory at Halley. As with the design of the 1973 Halley station, the Rothera complex has aroused considerable international interest.

Five main British Antarctic Survey stations were occupied throughout the year. These were Faraday and Halley (the two geophysical observatories), Signy (the main biological station), Grytviken (a multi-disciplinary sub-Antarctic station) and Rothera (the centre for air operations). The 1977 winter passed uneventfully and the stations were relieved in the 1977–78 summer, as usual, by the two Survey ships RRS John Biscoe and RRS Bransfield and two Twin Otter aircraft. However, ice conditions in the Antarctic Peninsula area were severe; although Halley was relieved without too much difficulty at the beginning of January, the ships were unable to reach Rothera until the end of February. By that time it was too late for major building operations, and the third and final phase of the development of Rothera (the construction of another large building) had to be postponed.

Jason Peninsula (66°10'S, 61°00'W) is a prominent feature extending some 80 km into the Larsen Ice Shelf from the eastern coast of the Antarctic Peninsula, and consists of widely spaced rock exposures and several ice-domes with elevations up to some 600 m (Fig. 1). The feature was first seen from seaward on 1 December 1893 by Captain C.A. Larsen, who named one of the high summits “Mount Jason” after his ship. Leading the 1902–1904 Swedish Antarctic Expedition, Dr Otto Nordenskjöld observed the area from Borchgrevink Nunatak (66°03'S; 62°30'W) and reported that the summits seen by Larsen were separated from the Antarctic Peninsula. The name “Jason Island” was subsequently adopted for this feature, but in the 1950s researchers belonging to the currently named British Antarctic Survey (BAS) determined Larsen's discovery to be a large peninsula, underlain mainly by calc-alkaline volcanic rocks.

Main Factor

Areas on different sides of the wharf of the Atlantic Biological Station that had been denuded in the spring and that had different degrees of illumination were selected and the growth of Balanus followed throughout the summer season. The results show (i) that there is a significant correspondence between rate of growth of Balanus and the amount of illumination, (ii) that the difference between the amount of growth at widely separated vertical levels is quite similar to the difference in the increment of growth in areas on the same level which are subject to wide variations in the amount of illumination, and (iii) that during the summer of 1931, there was no appreciable set of barnacles after June 6 in the St. Andrews region. The presence of a large number of elongated barnacles may result from the operation of one main factor or from the combination of several. It may indicate (i) that there has been a very heavy set, in which case exceptionally favorable growing conditions cannot necessarily be inferred, or (ii) a rapid rate of growth even though the set has not been particularly thick, or (iii) the presence of favorable growing conditions together with a good set. Each of these possibilities should be considered in the evaluation of Balanus balanoides as an organic indicator.

The accumulation of drifting snow around buildings in regions of severe climate has important implications on their design and location. This paper studies one such building, at a station run by the British Antarctic Survey and located on the Brunt Ice Shelf at the edge of the Antarctic continent. Four previous stations have been built in the area, the buildings of which were designed to become covered in snow and all have been crushed within a few years. The current station, Halley V, consists of three buildings which are all raised from the ice shelf by means of legs. They were designed in such a way that the action of the wind blowing underneath the buildings would keep them-clear of snow. This paper describes a model which predicts the shape and position of drift formation, and then compares the results with those observed at Halley. This model is a first attempt to address the problem and as such the paper can be considered to be a progress report; improvements arc currently being made as part of continuing research. It is found that there is some qualitative agreement and possible reasons for a few quantitative discrepancies are discussed. Both the model and the true data show clearly that the new design is very effective in prolonging the useful life of the buildings.

AbstractAntarctic Airways, an independent commercial airline, operated one DC-4 and two Twin Otter aircraft during the 1987–88 summer season. The DC-4 made twelve direct flights between Punta Arenas, Chile, and the Ellsworth Mountains. The Twin Otters were used for onward flights to destinations including the South Pole. The significance of this development is that scientists from countries that do not have ships or bases in the Antarctic can now work on the continent without either.

Permanent Presence

The British Antarctic Survey (BAS) has relied on sledge dogs as the main form of transport for field parties since its predecessor, the Falkland Islands Dependencies Survey (FIDS), imported them in 1945, when it created a permanent presence on the continent. Over the years dogs have been used for extensive work over a very wide area. In 1975 BAS changed its policy with respect to work in the southern Antarctic Peninsula. In future seasons scientists will not winter in this area but will be flown to Adelaide Island and then into the field. They will carry out more detailed scientific work in particular areas of interest. This means that it is no longer practical to maintain huskies on base as they could not be kept fit and well disciplined during the winter for a short summer season. The scientists, similarly, could not be expected to learn to work the dogs efficiently in the time available, and the change in the nature of their work means that they will not move camp so frequently. The dogs, since they must be fed even if they are resting, would be uneconomic in such a situation. Finally, most of the work will be in areas that are thought to be safe so the dogs will not be needed to probe for crevasses. In future seasons BAS will rely on skidoos for field work (Figs 1 and 2).

British Sector

Prior to 1962 work on freshwater within the British Sector of the Antarctic had been confined to the collection of specimens and their subsequent taxonomic evaluation. Collections were made by such expeditions as the Scottish National Antarctic Expedition 1902- 04, the various Discover y Investigations in this region 1925-37, the British Graham Land Expedition 1934-37 and the Falkland Islands Dependencies Survey 1945-62. During the 1961/1962 summer season an ecological investigation of the freshwater lakes of Signy Island, South Orkney Islands, was started. This paper is an interim report on that work.
