1. Bacterial community composition in relation to bedrock type and macrobiota in soils from the Sør Rondane Mountains, East Antarctica

   Antarctic soils are known to be oligotrophic and of having low buffering capacities. It is expected that this is particularly the case for inland high-altitude regions. We hypothesized that the […]

2. Low atmospheric CO2 levels during the Little Ice Age due to cooling-induced terrestrial uptake

   Low atmospheric carbon dioxide (CO2) concentration1 during the Little Ice Age has been used to derive the global carbon cycle sensitivity to temperature2. Recent evidence3 confirms earlier indications4 that the […]

3. Century-scale perspectives on observed and simulated Southern Ocean sea ice trends from proxy reconstructions

   Since 1979 when continuous satellite observations began, Southern Ocean sea ice cover has increased, whilst global coupled climate models simulate a decrease over the same period. It is uncertain whether […]

4. Modification of deep waters in Marguerite Bay, western Antarctic Peninsula, caused by topographic overflows

   Circumpolar Deep Water (CDW) intrudes from the mid-layers of the Antarctic Circumpolar Current onto the shelf of the western Antarctic Peninsula, providing a source of heat and nutrients to the […]

6. Diel periodicity of Subantarctic copepods: relationships between vertical migration, gut fullness and gut evacuation rate

   A zooplankton community in the Polar Frontal Zone north of South Georgia was sampled for 5 days in February 1994. Feeding of various copepodite stages of six copepod species was […]

7. Zooplankton response to a phytoplankton bloom near South Georgia, Antarctica

   A shelf site near the island of South Georgia was sampled during a spring bloom in January 1994. Chlorophyll a (chl a) values declined from 19 to 6 mg m-3 […]

8. Subantarctic copepods in an oceanic, low chlorophyll environment:ciliate predation, food selectivity and impact on prey populations

   Copepod feeding rates and food selectivity were measured at an oceanic subantarctic site over 5 d in February 1994. A series of gut fluorescence and gut evacuation experiments was carried […]

10. The foraging behaviour and energetics of wandering albatrosses brooding chicks

    The energy expenditure of ten (five male, five female) wandering albatrosses (Diomedea exulans Linnaeus 1758) brooding chicks on Bird Island, South Georgia, was measured using doubly-labelled water. At-sea foraging behaviour […]

11. The relationship between foraging behaviour and energy expenditure in Antarctic fur seals

    By using time-depth recorders to measure diving activity and the doubly-labelled water method to determine energy expenditure, the relationship between foraging behaviour and energy expenditure was investigated in nine Antarctic […]

12. Measuring the body composition of Antarctic fur seals (Arctocephalus gazella): validation of hydrogen isotope dilution

    We examined the accuracy of hydrogen isotope dilution (tritium and deuterium) as a means of determining total body water (TBW), and hence body composition, by comparison with whole-carcass chemical analysis […]
