The accuracy and efficiency with which radio echo parameters may be estimated by a programmable ionosonde of high resolution depend upon software-designed strategies of pulse set design and receiving antenna […]
The movements of two wandering albatrosses, one of each sex, breeding at South Georgia, were tracked using satellite telemetry, particularly to assess whether such birds could be at risk from […]
Maximum dive depths have been recorded for a number of sea-bird species using simple lightweight capillary gauges (Burger & Wilson 1988). So far these studies have been confined to penguins […]
A sedimentary sequence, c. 5–6 km thick, extending from the Kimmeridgian–Upper Eocene crops out in the James Ross Island area, northern Antarctic Peninsula. This succession is the most important onshore […]
The east coast of the Antarctic Peninsula is strongly influenced by air masses that have traversed the Weddell Sea zone. A continuous record of annual-average values for δ18O, δD, Cl− […]
A new desorber design for use in the couloximetric determination of oxygen in water samples is described. In comparison with previous systems it significantly improves the efficiency of transfer of […]
Brachiopods were once dominant in all the oceans of the world. but their distributions are non more restricted. There are few species which are found in shallow warm habitats and […]
