Seventeen species of Tardigrada from lakes and catchments on Signy Island, South Orkney Islands, are described. Two species, Echiniscus punctus and Isohypsibius laevis are new to science, and two, Oreella […]
The Fossil Bluff Grqup (FBG: ?Bathpnian-Albian) is the fill of a forearc basin which lay between the Antarctic Peninsula volcanic arc and an accretionary complex (LeMay Group) to the west […]
The structure of the cardiac foramen ovale from eight genera of pinnipeds was studied using the scanning electron microscope. Specimens were obtained from fetuses or neonates of the Californian sea […]
Previous work has shown that interplanetary scintillation (IPS) observations produce a poor forecast for geomagnetic activity. An explanation of some of the problems encountered would be the existence of an […]
Results are presented from a novel EISCAT special programme, SP-UK-BEAN, intended for the direct measurement of the ion temperature anisotropy during ion frictional heating events in the high-latitude F-region. The […]
The first ionospheric plasma convection maps ordered by the y- and z-components of the IMF using only data from the southern hemisphere are presented. These patterns are determined from line-of-sight […]
The plutonic rocks of the Antarctic Peninsula magmatic arc form one of the major batholiths of the circum-Pacific rim. The Antarctic Peninsula batholith is a 1350 km long by < […]
The abundance of both heterotrophic nanoflagellates (HNAN) and bacterioplankton in a large (9km2) ultraoligotrophic Antarctic lake (Crooked Lake) were investigated from December 1992 until November 1993. HNAN abundance peaked in […]
The first deep-tow boomer survey on the Antarctic continental margin has revealed relict subglacial deltas on the outer continental shelf off the Antarctic Peninsula. Progradation of subglacial deltas is thought […]
