1. Motion of the Scotia Sea plates

   Earthquake data from the Scotia Arc to early 2002 are reviewed in the light of satellite gravity and other data in order to derive a model for the motion of […]

2. Synchronization in the molting and spawning activity of northern krill (Meganyctiphanes norvegica) and its effect on recruitment

   The molting, spawning, and recruitment of northern krill (Meganyctiphanes norvegica) were analyzed over an annual cycle (1999-2000) in the Clyde Sea (west coast of Scotland). Results supported the hypothesis of […]

4. Sex-dependent diel vertical migration in northern krill Meganyctiphanes norvegica and its consequences for population dynamics

   The diel vertical migration (DVM) and population dynamics of northern krill were investigated in the Clyde Sea over several years using depth-discrete net-sampling and a moored 300 kHz acoustic Doppler […]

5. Research challenges at the land-sea interface

   The land–sea interface, or Coastal Transition Zone (CTZ), is the area that links terrestrial and marine habitats. We use here the definition of [Schaefer, 1972]: “the sea and the land […]

6. Foraging strategies of chinstrap penguins at Signy Island, Antarctica: importance of benthic feeding on Antarctic krill

   Chinstrap penguins Pygoscelis antarctica are one of the major consumers of Antarctic krill Euphausia superba in the Southern Ocean. To examine their foraging strategy, we studied foraging trip patterns and […]

7. Selective feeding by benthic foraminifera on phytodetritus on the western Antarctic Peninsula shelf: evidence from fatty acid biomarker analysis

   This study presents the first direct evidence, based on biochemical analysis of fresh material, that certain benthic foraminifera feed selectively on specific components of seasonally deposited phytodetritus in their natural […]

8. Numerical investigation of the effects of temporal variations in basal lubrication on englacial strain-rate distribution

   The effects of spatial and temporal variations in basal lubrication on the englacial strain rate and surface velocity distribution are investigated with a numerical ice-flow model. General aspects of the […]

9. Diurnal variations in vertical strain observed in a temperate valley glacier

   During a period of diurnal fluctuations in glacial flow speed, vertical strain was measured with sub-daily temporal resolution on Unteraargletscher, Switzerland. Mean vertical strain in boreholes up to 300-m deep […]

10. A late-glacial high-resolution site and source temperature record derived from the EPICA Dome C isotope records (East Antarctica)

    The timing and synchronisation of Greenland and Antarctic climate events that occurred during the last glacial period are still under debate, as is the magnitude of temperature change associated with […]

11. Identification of novel sulfur-containing derivatives of chlorophyll a in a Recent sediment

    Novel transformation products of chlorophyll a incorporating a methyl sulfide group in the substituent at the C-3 position have been identified in Recent sediments from an Antarctic lake.

12. The hydrochemistry of Lake Vostok and the potential for life in Antarctic subglacial lakes

    Our understanding of Lake Vostok, the huge subglacial lake beneath the East Antarctic Ice Sheet, has improved recently through the identification of key physical and chemical interactions between the ice […]
