The reduction of maximum usable frequency (MUF) during a geomagnetic storm represents a serious hindrance to the efficient operation of HF transmission links. This paper outlines a new approach to […]
We have carried out experiments to study the incorporation and movement of HCl within the structure of ice. These involved freezing HCl solutions, and observing them in a scanning electron […]
In crested penguins Eudyptes spp., the first-laid (A) egg is very much smaller than the second (B) egg and, although viable, rarely survives to hatching. I tested the recent hypothesis […]
The work of organizations in the UK to observe Comet Halley is reviewed. The activities of the Comet Halley UK Coordinating Committee are discussed. Results from space probes are summarized, […]
Upper Jurassic–Lower Cretaceous anoxic mudstones and air-fall ashes of the Nordenskjöld Formation are exposed on the eastern coast of Graham Land. Deformation of the strata has a long history spanning […]
The Nordenskjöld Formation is a sequence of thinly interbedded ash beds and black, radiolarian-rich mudstones which is exposed on the eastern coast of the Antarctic Peninsula. As a result of […]
Data from the 37 μm channel of the Advanced Very High Resolution Radiometer (AVHRR) are contaminated by interference which appears in the images as a herring-bone pattern. This interference has […]
Zooplankton was sampled intensively with an RMT 1+8M system in the fjord of Cumberland East Bay, South Georgia during late winter 1983 and summer 1987. In summer, biomass was highest […]
Ice motion in the Weddell Sea is examined for the period 19 August (Day 232) to 12 October (Day 286) 1986 using the tracks of four Argos buoys deployed during […]
