Antarctica is isolated, surrounded by the Southern Ocean, and has experienced extreme environmental conditions for millions of years, including during recent Pleistocene glacial maxima. How Antarctic terrestrial species might have […]
In the Southern Ocean the Antarctic Circumpolar Current is significantly steered by large topographic features, and sub-polar gyres form in their lee. The geometry of topographic features in the Southern […]
Hydrothermal vents at the East Scotia Ridge (ESR) were the first vents to be visually confirmed and surveyed in the Southern Ocean. A trochoid snail was recovered from low diffuse […]
The Southern Ocean and Antarctic region currently best represent one of the few places left on our planet with conditions similar to the preindustrial age. Currently, climate models have low […]
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) […]
During recent years there has been a steady increase in the total world fish catch (including shellfish) to a plateau, reached in the early 1970’s, of around 70 million tonnes. […]
An empirical model of the variation of electron concentration with height is described which overcomes some limitations found in practice with a previous widely used model (Bradley and Dudeney, 1973). […]
Dates of climatic episodes recorded in deep-sea cores are compared with the dates of palaeomagnetic polarity transitions during the Upper Pliocene period. The chance that the number of observed coincident […]
FLEXING of ice shelves may dissipate enough tidal energy to have a significant effect on the Moon’s retreat from the Earth. It is generally agreed that tidal friction slows the […]
