Scotia Sea regional tectonic evolution: implications for mantle flow and palaeocirculation
Read more of: Scotia Sea regional tectonic evolution: implications for mantle flow and palaeocirculationThe ScotiaSea and surrounding Scotia Arc have evolved over the past 40 Ma, by extension behind an east-migrating subduction zone, at the boundary between the South American (SAM) and Antarctic […]

Evolution of the Scotia Sea region: relevance to broad-band seismology
Read more of: Evolution of the Scotia Sea region: relevance to broad-band seismologyThis paper reports briefly an attempt to examine the tectonic evolution of the Scotia Sea region, in the context of the use of broad-band seismological techniques there. Such techniques can […]

Effect of summer frost exposures on the cold tolerance strategy of a sub-Antarctic beetle
Read more of: Effect of summer frost exposures on the cold tolerance strategy of a sub-Antarctic beetleThe sub-AntarcticbeetleHydromedion sparsutum (Coleoptera, Perimylopidae) is common locally on the island of South Georgia where sub-zero temperatures can be experienced in any month of the year. Larvae were known to […]

South Georgia, Antarctica: a productive, cold water pelagic ecosystem
Read more of: South Georgia, Antarctica: a productive, cold water pelagic ecosystemThe South Georgia region is characterised by high biomass and productivity of phytoplankton, zooplankton and vertebrate predators. Important commercial fisheries have been based at the island since the late 1700s, […]

A comparison between otoliths and scales for use in estimating the age of Dissostichus eleginoides from South Georgia
Read more of: A comparison between otoliths and scales for use in estimating the age of Dissostichus eleginoides from South GeorgiaAge composition is fundamental to understanding the population dynamics and productivity of a fish stock. The use of scales to estimate age can result in large errors in age data […]

Fasting metabolism in Antarctic fur seal (Arctocephalus gazella) pups
Read more of: Fasting metabolism in Antarctic fur seal (Arctocephalus gazella) pupsThe metabolism of 52–73-day old Antarcticfursealpups from Bird Island, South Georgia, was investigated during fasting periods of normal duration while their mothers were at sea foraging. Body mass decreased exponentially […]

Variation in maternal provisioning by lactating Antarctic fur seals (Arctocephalus gazella): response to experimental manipulation in pup demand
Read more of: Variation in maternal provisioning by lactating Antarctic fur seals (Arctocephalus gazella): response to experimental manipulation in pup demandAn experiment involving the supplementary feeding of pups was conducted on Antarctic fur seals to investigate the factors influencing maternal foraging-attendance cycles and the differential use of nutritional resources for […]

Age, growth and population structure of the jumbo flying squid Dosidicus gigas in Peruvian waters
Read more of: Age, growth and population structure of the jumbo flying squid Dosidicus gigas in Peruvian watersAge, growth and populationstructure of the jumboflyingsquid, Dosidicusgigas, from the jig fishery in Peruvianwaters in 1992 were determined by reading daily increments in ground and polished sections of statoliths. The […]
