Antarctic fisheries
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. […]

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 […]
To understand the recent dielectric measurements made on HF-doped ice single crystals requires a full knowledge of the concentration of electrical defects present in ice and their subsequent interactions. Previous […]
It is widely accepted that return currents from the auroral electrojet are responsible for the magnetic bays in the D component. The different directions of the return currents, at either […]
The major direct effects of man on seal populations are caused by hunting. Subsistence hunting using traditional methods has a long history and generally resulted in a balance between the […]
1. 1. Comparative analyses of standard metabolism, as measured by weight specific oxygen consumption, for Antarctic and temperate terrestrial Acari show that polar forms of the Cryptostigmata and Mesostigmata exhibit […]
