1. Early Oligocene Nothofagus from CRP-3, Antarctica: implications for the vegetation history

   A single fossil leaf of Nothofagus from CRP-3 drillhole in the Victoria Land Basin provides further evidence for woody vegetation in the Tertiary of East Antarctica. The plicate vernation of […]

4. Recent aqueous environments in Martian impact craters: an astrobiological perspective

   The discovery of gullies and debris aprons raises the question of the existence of aqueousenvironments on Mars in recent geological times and its astrobiological implications. Three cases of such environments […]

5. Global relationships amongst black-browed and grey-headed albatrosses: analysis of population structure using mitochondrial DNA and microsatellites

   The population structure of black-browed (Thalassarche melanophris and T. impavida) and grey-headed (T. chrysostoma) albatrosses was examined using both mitochondrial DNA (mtDNA) and microsatellite analyses. mtDNA sequences from 73 black-browed […]

6. Enhanced magma supply at the southern East Scotia Ridge: evidence for mantle flow around the subducting slab?

   Bathymetric and seismic data show that the southernmost segment of the EastScotia Ridge (segment E9) is anomalous in its curved plan form, and in the presence of a large axial […]

7. Seasonality of feeding and nutritional status during the austral winter in the Antarctic sea urchin Sterechinus neumayeri

   The seasonal pattern of food intake and tissue energy status was measured over a 2 year period for two populations of the common Antarctic echinoid Sterechinus neumayeri living on contrasting […]

8. Seasonality of respiration and ammonium excretion in the Antarctic echinoid Sterechinus neumayeri

   Oxygen consumption (MO2) and ammonium excretion rates were recorded monthly over 2 yr for the regular Antarctic echinoid Sterechinus neumayeri to investigate metabolic activity in relation to seasonal food limitation […]

9. The relative influence of temperature and food on the metabolism of a marine invertebrate

   Many benthic marine invertebrates exhibit a seasonal cycle in activities such as feeding, growth and reproduction. In temperate regions, this seasonality is typically correlated with coincident cycles in photoperiod, temperature […]

10. The seasonal energetics of the Antarctic bivalve Laternula elliptica (King and Broderip) at Rothera Point, Adelaide Island

    Seasonal changes in feeding activity, metabolic rate and major tissue energy concentrations of the infaunal bivalve Laternula elliptica were monitored over a 12 degrees month period in relation to phytoplankton […]

11. Acoustic observations of jellyfish in the Namibian Benguela

    Multi-frequency acoustic data (18, 38 and 120 kHz) were collected in conjunction with pelagic trawl sampling for gelatinous macrozooplankton during a cruise to the Namibian Benguela in September 1999. Sampling […]

12. Diving depths of northern gannets: acoustic observations of Sula bassana from an autonomous underwater vehicle

    The Autonomous Underwater Vehicle (AUV) Autosub-1 made observations of the sea surface with an upward-looking echosounder during fish surveys in the vicinity of Shetland and Orkney (North Sea) in July […]
