1. Cenozoic tectonic history of the South Georgia microcontinent and potential as a barrier to Pacific-Atlantic through flow

   Cenozoic opening of the central Scotia Sea involved the tectonic translation of crustal blocks to form the North Scotia Ridge, which today is a major topographic constriction to the flow […]

2. An exception to the rule: Carry-over effects do not accumulate in a long-distance migratory bird

   Recent years have seen a growing consensus that events during one part of an animal’s annual cycle can detrimentally affect its future fitness. Notably, migratory species have been shown to […]

3. Modelling ice-ocean interaction in ice shelf crevasses

   Ocean freezing within ice-shelf basal crevasses could potentially act as a stabilizing influence on ice shelves; however, ice-ocean interaction and ocean dynamics within these crevasses are as yet poorly understood. […]

4. Bycatch of great albatrosses in pelagic longline fisheries in the southwest Atlantic: Contributing factors and implications for management

   Pelagic longline fisheries in the southwest Atlantic are a major conservation concern for several threatened seabirds, including four species of great albatrosses: wandering albatross (Diomedea exulans), Tristan albatross (Diomedea dabbenena), […]

5. Tracking fitness in marine vertebrates: current knowledge and opportunities for future research

   For more than 60 yr, electronic tags (including acoustic transmitters, archival loggers, and satellite tags) have been applied to free-ranging marine vertebrates to track their behaviour and characterize their spatial […]

7. Palaeoenvironmental records from the West Antarctic Peninsula drift sediments over the last 75 ka

   We present results of a multi-proxy study on marine sediment core JR179-PC466 recovered from the crest of a sediment drift off the West Antarctic Peninsula at approximately 2300 m water […]

8. Heat-flow determinations of basement age in small oceanic basins of the southern central Scotia Sea

   Results are reported from seven heat flow stations in small basins of the southern part of the central Scotia Sea (CSS), undertaken in order to determine basement ages. The basins […]

9. Pb isotopic domains from the Indian Ocean sector of Antarctica: implications for past Antarctica-India connections

   New feldspar lead isotope compositions of crystalline rocks from the Indian Ocean sector of East Antarctica, in conjunction with the review of data from elsewhere within the continent and from […]

10. Energetic electron precipitation characteristics observed from Antarctica during a flux dropout event

    Data from two autonomous VLF radio receiver systems installed in a remote region of the Antarctic in 2012 is used to take advantage of the juxtaposition of the L = 4.6 contour, […]

11. Whales from space: counting southern right whales by satellite

    We describe a method of identifying and counting whales using very high resolution satellite imagery through the example of southern right whales breeding in part of the Golfo Nuevo, Península […]

12. Determining the spectra of radiation belt electron losses: Fitting DEMETER electron flux observations for typical and storm times

    The energy spectra of energetic electron precipitation from the radiation belts are studied in order to improve our understanding of the influence of radiation belt processes. The Detection of Electromagnetic […]
