The creep of ice shelves theory
1 January, 1973
Budd’s expressions for strain-rate gradient along the centre line of a bounded ice shelf are shown to be applicable only to ice shelves with almost constant thickness and very small…The creep of ice shelves: interpretation of observed behaviour
1 January, 1973
Available measurements of creep rates and dimensions of ice shelves are used, in conjunction with equations derived in a companion paper (Thomas, 1973), to evaluate the flow law parameters B…Read more on The creep of ice shelves: interpretation of observed behaviour
The geology of Powell, Christoffersen and Michelsen Islands, South Orkney Islands
1 January, 1973
Available measurements of creep rates and dimensions of ice shelves are used, in conjunction with equations derived in a companion paper (Thomas, 1973), to evaluate the flow law parameters B…Read more on The geology of Powell, Christoffersen and Michelsen Islands, South Orkney Islands
The geology of the Falkland Islands
1 January, 1972
This was published with two map sheets (ref DOS 1185A & 1185B), which are included as separate TIFF files, and with a 21-page gazetteer, which has been scanned as part…The bacteria in an Antarctic peat
1 January, 1972
Of a total of 119 strains of bacteria from 3 depths in an acid peat on Signy Island, S. Orkney, 52% belonged to the genus Brevibacterium. Twelve other genera were…The effects of reduced sucrose intake on the formation and composition of dental plaque in a group of men in the Antarctic
1 January, 1972
Sucrose was omitted from the diet of a group of 19 men over a period of 14 weeks, and replaced by glucose syrup and calcium cyclamate. Dental plaque was assessed…Automatic plotting of airborne geophysical survey data
1 January, 1972
When geophysical measurements are made from the air, it is important to know the position of the aircraft. The position at any time is usually known from a combination of…Read more on Automatic plotting of airborne geophysical survey data
Radio echo sounding: Absorption and Scattering by water inclusion and ice lenses
1 January, 1972
The absorption of radio waves propagating through naturally occurring waters varies greatly with the electrical conductivity. Glacier melt water is very transparent and the attenuation by melt water layers is…Read more on Radio echo sounding: Absorption and Scattering by water inclusion and ice lenses
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
