2. SeaWiFs in the southern ocean: spatial and temporal variability in phytoplankton biomass around South Georgia

   SeaWiFS was used to examine the spatial and temporal distribution of chlorophyll-a (chl-a) concentrations around the island of South Georgia during four summers between October 1997 and March 2001. A […]

3. Contrasting primary production regimes around South Georgia, Southern Ocean: large blooms versus high nutrient, low chlorophyll waters

   During the austral summer of 2002, a large and persistent phytoplankton bloom was detected with SeaWiFS imagery in the Georgia Basin to the north-west of South Georgia, while waters to […]

4. Seismic evidence for a water-filled canal in deforming till beneath Rutford Ice Stream, West Antarctica

   Seismic data from Rutford Ice Stream, West Antarctica show high amplitude, reversed-polarity reflections from parts of the bed. Only interfaces between ice and water, or between water and sediment have […]

5. Salp distribution and size composition in the Atlantic sector of the Southern Ocean

   Salp abundance and length frequency were measured during the large-scale CCAMLR 2000 Survey conducted in the Atlantic Sector of the Southern Ocean in the 1999/2000 season. Results from regional surveys […]

6. Model calculations of the age of firn air across the Antarctic continent

   The age of firn air in Antarctica at pore close-off depth is only known for a few specific sites where firn air has been sampled for analyses. We present a […]

7. A comparison of net and acoustic estimates of krill density in the Scotia Sea during the CCAMLR 2000 Survey

   A multi-ship, multi-national survey to assess the acoustic biomass of Antarctic krill across the Scotia Sea was undertaken in January and February 2000. In addition, a total of 135 Rectangular […]

8. Frost flowers on sea ice as a source of sea salt and their influence on tropospheric halogen chemistry

   Frost flowers grow on newly-formed sea ice from a saturated water vapour layer. They provide a large effective surface area and a reservoir of sea salt ions in the liquid […]

10. Role of antioxidant defense during different stages of preadult life cycle in European corn borer (Ostrinia nubilalis, Hubn.): diapause and metamorphosis

    Antioxidant enzymes, total glutathione (GSH), and ascorbic acid (ASA) were determined in whole body homogenates of nondiapausing larvae, diapausing larvae during the diapausing period (October, December, and February), and in […]

11. Winter dispersal of leopard seals (Hydrurga leptonyx): environmental factors influencing demographics and seasonal abundance

    The dynamics of leopard seat Hydrurga leptonyx abundance and residency were investigated both within and between years at Bird Island, South Georgia, using observations of tagged and untagged individuals. Seals […]

12. Seasonal ventilation of the cavity beneath Filchner-Ronne Ice Shelf simulated with an isopycnic coordinate ocean model

    [1] The ocean cavity beneath Filchner-Ronne Ice Shelf is observed to respond to the seasonal cycle of water mass production on the continental shelf of the southern Weddell Sea. Here […]
