Oxygen uptake in an Antarctic collembole Cryptopygus antarcticus
1 January, 1972 by William Block
The relationship between length and weight was investigated for the Antarctic springtail, Cryptopygus antarcticus Willem. The range of individuals from juvenile to adult was divided arbitrarily into five size classes,…Read more on Oxygen uptake in an Antarctic collembole Cryptopygus antarcticus
Glacier movement measured with a radio echo technique
1 January, 1972
In the radio echo sounding method for measuring the thickness of polar ice masses, the sounder transmits regular pulses each containing several cycles of VHF radio waves into the ice.…Read more on Glacier movement measured with a radio echo technique
The breeding biology of the black-bellied storm-petrel Fregetta tropica
1 January, 1971
The breeding cycie and habits of the Black‐bellied Storm‐petrel are described from observations made over three seasons at Signy Island, South Orkney Islands. The species is strictly nocturnal on land…Read more on The breeding biology of the black-bellied storm-petrel Fregetta tropica
Genetic defects in Antarctic dogs
1 January, 1971
The occurrence of congenital entropion and true haemophilia in a closed population of working British Antarctic Survey sledge dogs is described. The difficulties of determining the patterns of inheritance are…The growth of Phleum alpinun L. in contrasting habitats at a sub-Antarctic station
1 January, 1971
The effects of aerial microclimate and edaphic conditions on the growth of young vegetative tillers of Phleum alpinum L. from contrasting habitats on South Georgia have been investigated using growth…Read more on The growth of Phleum alpinun L. in contrasting habitats at a sub-Antarctic station
Productivity of bryophytes in polar regions
1 January, 1971
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…Studies of respiratory viruses in personnel at an Antarctic base
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
Algorithm for the production of contour maps from linearized data
1 January, 1971
Cole has proposed an algorithm which produces a generalized surface for contouring scattered data1. The algorithm works well when the data points are randomly distributed but improbable results have been…Read more on Algorithm for the production of contour maps from linearized data
Flow law for Antarctic ice shelves
1 January, 1971
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…Plate tectonics of the Scotia Sea region
1 January, 1970
A newly defined small lithospheric plate in the eastern Scotia Sea accounts for the intense seismicity at the South Sandwich Trench.A seasonal change in the diurnal rhythm of the excretion of a 3-methoxy-4-hydroxymandelic acid in man
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…The relationship of diet to serum cholesterol levels in young men in Antarctica
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
Satellite photographs of the Antarctic Peninsula Area
1 January, 1970
The British Antarctic Survey (BAS) has been receiving regular satellite photo coverage of the Antarctic Peninsula area since 1967. Supplied by courtesy of the United States Environmental Science Services Administration…Read more on Satellite photographs of the Antarctic Peninsula Area
Survey on moving ice
1 January, 1970
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…Bottom melting of ice shelves and the mass balance of Antarctica
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
A radio echo equipment for depth sounding in polar ice sheets
1 February, 1969
The glaciological need for depth-sounding in glaciers, ice sheets, and ice shelves is discussed. A v.h.f. radar, designed specifically to produce continuous profiles of ice depth is described. Some practical…Read more on A radio echo equipment for depth sounding in polar ice sheets
Volcanic activity at Deception Island in 1967 and 1969
1 January, 1969
Eruptions, apparently associated with the caldera fault zone, have created a new island and a new 5 km fissure. Several explosive vents along the fissure caused a rift in the…Read more on Volcanic activity at Deception Island in 1967 and 1969
The early development of Pygoscelis adeliae(Adélie penguin) up to the formation of the neural tube
1 January, 1969
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…
