1. Ecophysiology of antarctic marine ectotherms: limits to life

   The ecophysiology of Antarctic marine ectotherms is an area of active research. This review of recent progress covers metabolism, mitochondrial function, aerobic scope, growth and development. Energetics is shown to […]

2. Short-term stability of the microbial community structure in a maritime Antarctic lake

   Spatial and temporal changes in the microbial community structure in a maritime Antarctic freshwater lake were investigated over a single day/night cycle in December 1999. The community structure of key […]

4. Signatures of the midnight open-closed magnetic field line boundary during balanced dayside and nightsife reconnection

   The geomagnetic conditions were moderately disturbed (Kp = 2) during magnetic midnight on 10 December 1999, when the Tasman International Geospace Environment Radar (TIGER), a Southern Hemisphere HF SuperDARN radar, […]

6. Global-scale tidal variability during the PSMOS campaign of June-August 1999: interaction with planetary waves

   During the PSMOS Global-scale tidal variability experiment campaign of June 1-August 31, 1999, a network of radars made measurements of winds, waves and tides in the mesosphere/lower-thermosphere region over a […]

7. Global-scale tidal structure in the mesosphere and lower thermosphere during the PSMOS campaign of June-August 1999 and comparisons with the global-scale wave model

   Observations of mean winds and semidiurnal and diurnal tides in the mesosphere/lower-thermosphere (MLT) region were made during the 3-month Planetary-Scale Mesopause Observing System Summer 1999 campaign. Data from 22 ground-based […]

8. More evidence of speciation and dispersal across the Antarctic Polar Front through molecular systematics of Southern Ocean Limatula (Bivalvia: Limidae)

   The previously unclear taxonomic status of the high-Antarctic bivalve Limatula ovalis Thiele, 1912 and the sub-Antarctic L. pygmaea (Philippi, 1845) was investigated using molecular techniques (18S rDNA, 16S rDNA, ITS-1). […]

9. Palaeobiogeography and the Ordovician and Mesozoic-Cenozoic biotic radiations

   Curves of taxonomic diversity through geological time consistently show major evolutionary radiations during the Ordovician Period and from the mid-Mesozoic to the present day. Both intervals were characterized by marked […]

10. Survival in king penguins Aptenodytes patagonicus: temporal and sex-specific effects of environmental variability

    We investigated annual adult survival rates of king penguins Aptenodytes patagonicus breeding at South Georgia during 6 years in relation to age/breeding experience, sex, and food availability. During the first […]

11. New and rare moss species from subantarctic South Georgia

    Forty-one species of moss are reported from the subantaretic island of South Georgia. Twenty-two of these are recorded for the first time from the island, namely Andreaea obovata Thed. (first […]

12. Sediment reworking on high-latitude continental margins and its implications for palaeoceanographic studies: insights from the Norwegian-Greenland Sea

    Geological evidence indicates that sediment reworking is common around the continental margins and abyssal depths of the Norwegian-Greenland Sea, a high-latitude setting with glacier-influenced margins. Detailed analysis of 22 cores […]
