1. Seed germination of endemic species from Kerguelen phytogeographic zone

   Seeds of six endemic species and two circumpolar species were collected from several sites on Kerguelen and tested for germination between 5 and 25°C on thermogradient bars. Pringlea antiscorbutica and […]

2. Nonmarine sedimentation in an Early Cretaceous extensional continental-margin arc, Byers Peninsula, Livingston Island, South Shetland Islands

   Upper Jurassic-Lower Cretaceous rocks of the Byers Group, exposed on Byers Peninsula, Livingston Island, record the expansion of Gondwana-margin continental-arc facies into a marine intra-arc basin. At least 1.3 km […]

3. An analysis of a 34-year air temperature record from Fossil Bluff (71°S, 68°W), Antarctica

   An analysis of a long-term surface air temperature record for Fossil Bluff in the George VI Sound, West Antarctic Peninsula (WAP) documents in detail some important aspects of the climate […]

4. Atmospheric meridional circulation impacts on contrasting winter sea ice extent in two years in the Pacific sector of the Southern Ocean

   An explanation is sought for the marked variation in maximum sea ice extent observed between 2 years in the 2 areas of greatest interannual variability in winter ice extent in […]

6. Rock temperatures and implications for cold region weathering. I: New data from Viking Valley, Alexander Island, Antarctica

   A principal tenet of cold region weathering studies is that of temperature. Unfortunately, despite the appearance to the contrary, actual data are still sadly lacking in many instances. Here data […]

7. Observations on “cryoplanation” benches in Antarctica

   A series of benches on nunataks of Alexander Island (Antarctica) are described. An increase in bench size with distance away from the retreating glacier suggests an age spectrum. The benches […]

8. Effect of cold acclimation on the antioxidant defense system of two larval lepidoptera (noctuidae)

   Activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione-S-transferase (GST), as well as total glutathione (tGSH) concentration were analyzed in the hemolymph and fat body […]

10. Small-scale interactions between prions Pachyptila spp. and their zooplankton prey at an inshore site near Bird Island, South Georgia

    We investigated the relationship between surface-foraging prions Pachyptila spp. and their zooplankton prey by comparing counts of foraging birds with near-surface concentrations of zooplankton from net samples. Zooplankton abundance was […]

11. Interactions between oceanography, ecology and fishery biology of the ommastrephid squid Martialia hyadesi in the South Atlantic

    The seven star flying squid Martialia hyadesi is an oceanic slope ommastrephid with a circumpolar distribution associated with the Antarctic Polar Frontal Zone (APFZ) and is a minor, variable catch […]

12. Photogrammetry as a research tool for glaciology

    Using a multidisciplinary project studying surging glaciers in Svalbard as a reference, this paper examines some of the ways in which photogrammetry can be used as a research tool by […]
