The productivity of various South Georgian moss species has been measured and some comparative data from Disko Island, West Greenland, are also considered. Two main aspects of growth have been…1 January, 1971
Thirteen men wintering on an Antarctic base were isolated from other human contact for 10 months. During this period Coxsackievirus A21 and later influenza A2 virus were administered to some…Read more on Studies of respiratory viruses in personnel at an Antarctic base

Ice shelves are floating glaciers which are attached to an inland ice sheet or to land. They creep under their own weight, the creep rates being dependent on the ice…1 January, 1970
A newly defined small lithospheric plate in the eastern Scotia Sea accounts for the intense seismicity at the South Sandwich Trench.1 January, 1970
In two series of experiments, one in the autumn and one in the winter on an Antarctic base, diurnal rhythms have been demonstrated in the urinary excretion of V.M.A. These…1 January, 1970
1. Regular estimations of dietary intake, body-weight, skinfold thickness, blood pressure and pulse rate, and serum lipids were made in twenty-four members of an Antarctic expedition over 1 year. 2.…Read more on The relationship of diet to serum cholesterol levels in young men in Antarctica

In order to measure ice deformation at frequent intervals across the Brunt Ice Shelf, Antarctica, 64 markers were planted to form a network of overlapping braced quadrilaterals. This network was…1 January, 1970
THE world sea level is estimated1,2 to be rising by approximately 1 mm yr−1. Attempted explanations3,4 have considered heating of the oceans, release of juvenile water, a reduction in atmospheric…Read more on Bottom melting of ice shelves and the mass balance of Antarctica

The early embryonic development of Pygoscelis adeliae, up to the stage with fused neutral folds, was investigated by means of serial sections and compared with the development of the chick…1 January, 1969
Two giant icebergs are moving westwards along the coast of Antarctica in the Weddell Sea. They were conspicuous throughout the 1967–68 season in ESSA-3 satellite photographs supplied by the United…1 January, 1968
Comparisons are made between the Lesser Antilles and the South Sandwich Islands, the recent volcanic island chains at the eastern margins of the Caribbean and Scotia arcs. Although situated in…Read more on Comparative volcanology and petrology of the atlantic island-arcs
