1. The relationship between water content and cold tolerance in the arctic collembolan Onychiurus arcticus (Collembola: Onychiuridae)

   The arctic collembolan Onychiurus arcticus is freezing intolerant and experiences temperatures below -25°C during winter periods of low air temperatures and only light snow cover. Summer-collected individuals have a mean […]

3. The record of aerosol deposited species in ice cores, and problems of interpretation

   Ice cores have now become established as one of the primary archives of paleoclimatic information, covering timescales from seasonal up to 100,000 years or more. In the polar ice sheets, […]

4. Location, movement and reactions of impurities in solid ice

   The aim of drilling ice cores is to obtain paleoatmospheric information of wide significance. However, the concentrations of chemicals found in the- ice are determined both by the atmospheric concentrations, […]

5. Seasonal variation in vitamin D metabolites in southern elephant seal (Mirounga leonina) females at south Georgia

   Southern elephant seals spend two periods on land each year, during breeding and moult, exposed to intensive UV radiation. The time between periods on land are spent at sea, with […]

6. Sulphur sources for epithermal and mesothermal veins in Cretaceous-Tertiary magmatic-arc rocks, Livingston Island, South Shetland Islands

   Epithermal veins in early Triassic turbidites on Hurd Peninsula are isotopically homogeneous over an area of 13 km × 2 km (mean δ34S = +2.2‰, 1σ= 1.7, n = 65) […]

7. The Moores Peak Formation, a Cretaceous debris-avalanche deposit in the Antarctic Peninsula Volcanic Group, Livingston Island, South Shetland Islands

   The Moores Peak Formation occurs on eastern Hurd Peninsula, Livingston Island, part of the South Shetland Island volcanic arc, which was active during Mesozoic and Cenozoic times. The rocks were […]

8. Seasonal variation in the effects of hard substratum biofilming on settlement of marine invertebrate larvae

   The effect of season on “biofilming”;, as a cue for the settlement of marine invertebrate larvae, was investigated in a long‐term field study during the years 1992–1994. The series of […]

9. Substantial open-ocean phytoplankton blooms to the north of South Georgia, South Atlantic, during summer

   Substantial open-ocean phytoplankton blooms in the Antarctic Zone to the northwest of South Georgia, South Atlantic are described. Chlorophyll a, nutrient and physical oceanography data, collected between 2 and 5 […]

10. Seasonal and annual change in seawater temperature, salinity, nutrient and chlorophyll a distributions around South Georgia, South Atlantic

    Data collected between 1926 and 1990, during the Discovery Investigations and fourteen subsequent cruises, have allowed the description of spatial and temporal variability of temperature, salinity, phosphate, silicate, nitrate and […]

11. Acanthocephalan infection of inshore fishes at the South Orkney Islands

    An examination of notothenioid fish of three species, including 23 immature Notothenia coriiceps Richardson, revealed seven acanthocephalan species, including two Echinorhynchida occurring in the intestine and five Polymorphida in the […]

12. Egg-shell morphology of the Antarctic fish, Notothenia rossii Richardson, and the distribution and abundance of pelagic eggs at South Georgia

    During winter research cruises to South Georgia (1983 and 1993) fish eggs were abundant in the neuston. Examination of the external sculpturing and the micropyle morphology of the eggs collected […]
