Mackerel icefish, Champsocephalus gunnari, larvae were sampled by weekly plankton tows in Cumberland Bay South Georgia. The formation of daily growth increments in sagittal otoliths was validated from larvae sampled […]
Historic upper-air observations from Antarctica are inspected to investigate the uniqueness of the vortex split in the Antarctic spring of 2002. No comprehensive meteorological observations are available prior to the […]
UV-B radiation (280–315 nm), incident on the leafy liverwort Cephaloziella varians growing at Rothera Point on the Western Antarctic Peninsula, was manipulated in late austral spring 1998 by screens consisting […]
This study analysed the total length (LT)-frequency distribution of mackerel icefish Champsocephalus gunnari at South Georgia and Shag Rocks from nine bottom trawl surveys at South Georgia and eight at […]
Geophysical data show that during the last glaciation the West Antarctic Ice Sheet (WAIS) drained to the continental shelf edge of the Bellingshausen Sea through a cross-shelf bathymetric trough (Belgica […]
Geophysical and geological data indicate that during the last glacial cycle a palaeo-ice stream drained the Antarctic Peninsula Ice Sheet (APIS) through Marguerite Bay to the edge of the continental […]
Temperature observations between 20 and 120 km from the SABER instrument on the TIMED spacecraft are used to investigate the nature of planetary wave activity during the 60 days prior […]
Scophthalmus maximus is an important commercially aquaculture fish species. We tackle the search for new microsatellites using two different approaches: an enriched partial genomic library and a screening of all […]
The comparatively low latitude of the Tasman International Geospace Environment Radar (TIGER) (147.2°E, 43.4°S, geographic; −54.6°Λ), a Southern Hemisphere HF SuperDARN radar, facilitates the observation of extensive backscatter from decametre-scale […]
Earthward injections of energetic ions and electrons mark the onset of magnetospheric substorms. In the inner magnetosphere (L~4), the energetic ions drift westward and the electrons eastward, thereby enhancing the […]
The MODVOLC satellite monitoring system has revealed the first recorded eruption of Mount Belinda volcano, on Montagu Island in the remote South Sandwich Islands. Here we present some initial qualitative […]
In this study, variation in the bacterioplankton community structure of three Antarctic lakes of different nutrient status, was determined in relation to physical and chemical gradients at depth and at […]
