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…Our publications

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…Giant icebergs in the Weddell Sea, 1967–68
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…The vascular flora of the Falkland Islands
1 January, 1968
This was published with two map sheets (ref DOS(Misc) 453), which are included as separate TIFF files.Comparative volcanology and petrology of the atlantic island-arcs
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
The respiratory metabolism of some Antarctic fish
1 January, 1968
1. The metabolic rates of four Antarctic fish have been measured, including the haemoglobin-less Chaenocephalus aceratus. 2. The respiratory rates of the fish are discussed in relation to body weights.…Read more on The respiratory metabolism of some Antarctic fish
Adoptive suckling in the grey seal
1 January, 1968
Almost all accounts of the natural history of the grey seal Halichoerus grypus give the impression that a cow invariably seeks and feeds only her own pup among the dozens…Field measurements of dielectric absorption in Antarctic ice and snow at very high frequencies
1 January, 1968
Field measurements are presented of dielectric absorption in Antarctic snow and ice at frequencies of a few hundred megahertz. They are compared with measurements by other authors at very high…Factors affecting the availability of plant nutrients on an Antarctic island
1 January, 1967
An examination of material from Signy Island, in the South Orkney group, shows that large amounts of plant nutrients are moving through the ecosystem of the island. Physical weathering is…Read more on Factors affecting the availability of plant nutrients on an Antarctic island
Soil types and nutrients on Signy Island
1 January, 1967
Although all the soils on Signy Island are at an early stage of development a number of contrasting types are present. In this report the influence of the various internal…Food intake in Antarctica
1 January, 1967
1. Body-weight, skinfold thickness and food intake were measured at regular intervals in twenty-five young men while on an Antarctic expedition. 2. The mean calorie intake over the year was…
