1. 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 […]

3. 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, […]

5. 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 […]

6. 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 […]

7. 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). […]

8. 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 […]

9. 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 […]

10. 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 […]

11. 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 […]

12. Temperature effects on the metabolism of larvae of the Antarctic starfish Odontaster validus, using a novel micro-respirometry method

    Oxygen consumption of individual larvae of the Antarctic sea-star Odontaster validus was measured during the 50-day period following fertilisation. Values ranged from 0.76 pmol O-2 h(-1) for one specimen at […]
