Early stages of toothfish are reported from cruises between 1978 and 2001. South Georgia was regularly sampled, Shag Rocks was briefly sampled in three summers, and Burdwood Bank was sampled […]
The oxygen and hydrogen isotope composition of waters in a small valley at Signy Island, South Orkney Islands, were monitored over three summers (1999 to 2001). These stable isotopes track […]
[1] One example of the response of ionospheric convection and the polar cap boundary to a sudden change in the interplanetary magnetic field (IMF) orientation has been studied by using […]
The Cretaceous Fossil Bluff Group on Alexander Island, on the west side of the Antarctic Peninsula, contains a remarkably complete record of the evolution of a forearc basin. The latest […]
Three species of biennial breeding southern hemisphere albatrosses-Diomedea sanfordi from the Chatham Islands, D. antipodensis from Antipodes Island and D. exulans from South Georgia-were tracked using CLS-Argos satellite system during […]
Analysis of a single traveling convection vortex (TCV) event that combines magnetometer, auroral imager, and riometer observations from conjugate hemispheres provides a complete view of the field-aligned current (FAC) system […]
The present study reveals the ionospheric signature of low level near-Earth flow burst activity in the central plasma sheet during a relatively quiet magnetosphere. Flow bursts were observed by Geotail […]
Two medium-depth ice cores were retrieved from Berkner Island by a joint project between the Alfred-Wegener-Institut and the British Antarctic Survey in the 1994/95 field season. A151mdeep core from the […]
Taking as a model the Alfred Wegener Institute medium depth ice core drill, we have developed a drill capable of retrieving ice cores to depths of around 150-200m. At a […]
A recent major climatic event was the occurrence of approximately 350 000 square kilometers of open water in the normally ice covered Weddell Sea near Antarctica during the winters of […]
With the completion of the NCEP-NCAR and ECMWF reanalyses there are now global representations of air-sea surface heat fluxes with sufficient spatial and temporal resolution to be useful in characterizing […]
