2. Environmental response of upper trophic-level predators reveals a system change in an Antarctic marine ecosystem

   Long-term changes in the physical environment in the Antarctic Peninsula region have significant potential for affecting populations of Antarctic krill (Euphausia superba), a keystone food web species. In order to […]

3. The use of predator-derived length-frequency distributions to calculate krill target strength

   The relationship between krill abundance and predator performance is fundamental to an ecosystem-based approach to resource management. We propose a method using krill sampled from the diet of predators to […]

4. Growth of Antarctic krill Euphausia superba at South Georgia

   Antarctic krill Euphausia superba has a central role in the ecosystem of the Southern Ocean and knowledge of its growth rate is central to determining the factors influencing population dynamics. […]

5. Regulation by low temperature of phytoplankton growth and nutrient uptake in the Southern Ocean

   During oceanographic cruises in 1996 and 1998, phytoplankton from 15 stations in the southwest Atlantic sector of the Southern Ocean were incubated at ambient temperature and 2 elevated temperatures (ambient […]

7. Ice in the earth system: the view from above

   The cryosphere is a key component of the Earth system, with important linkages and feedbacks affecting the radiative balance of the planet, the circulation of the oceans and atmosphere, global […]

8. Population trends, breeding success and diet composition of gentoo Pygoscelis papua, magellanic Spheniscus magellanicus and rockhopper Eudyptes chrysocome penguins in the Falkland Islands

   Data on population size, breeding success and diet composition of gentoo (Pygoscelis papua), magellanic (Spheniscus magellanicus) and rockhopper (Eudyptes chrysocome) penguins, collected as part of the Falkland Island Seabird Monitoring […]

9. Littoral Acari of Marion Island: ecology and extreme wave action

   Fourteen species of littoral Acari (Arachnida) were collected from the shores of sub-Antarctic Marion Island, of which Parasitiphis brunneus (Kramer) (Ologamasidae), Rhombognathus apsteini Lohmann and R. gressitti Newell (Halacaridae) are […]

10. Bathymetry and acoustic facies beneath the former Larsen-a and Prince Gustav ice shelves, NW Weddell Sea

    We present preliminary results of the first detailed surveys of the former Larsen-A Ice Shelf, Larsen Inlet aiid southern Prince Gustav Channel. where disintegration of small ice shelvcs in the […]

11. An examination of inter-hemispheric conjugacy in a subauroral polarization stream

    During geomagnetically disturbed conditions the midlatitude ionosphere is subject to intense poleward directed electric fields in the dusk-midnight sector. These electric fields lead to the generation of a latitudinally narrow […]

12. First survey of Antarctic sub-ice shelf sediments reveals mid-Holocene ice shelf retreat

    The retreat of five small Antarctic Peninsula ice shelves in the late 20th century has been related to regional (possibly anthropogenic) climate warming. We use the record of ice- rafted […]
