Foraging location and range of white-chinned petrels Procellaria aequinoctialis breeding in the South Atlantic
Read more of: Foraging location and range of white-chinned petrels Procellaria aequinoctialis breeding in the South AtlanticThe foraging range and principal feeding areas of White-chinned Petrels breeding at South Georgia were determined using satellite telemetry. Foraging trips during incubation lasted 12–15 days and covered 3000–8000 km […]

Synkinematic emplacement of Lassiter Coast Intrusive Suite plutons during the Palmer Land Event: evidence for mid-Cretaceous sinistral transpression at the Beaumont Glacier in eastern Palmer Land
Read more of: Synkinematic emplacement of Lassiter Coast Intrusive Suite plutons during the Palmer Land Event: evidence for mid-Cretaceous sinistral transpression at the Beaumont Glacier in eastern Palmer LandNew structural and geochronological data from the Eastern Palmer Land Shear Zone, in the vicinity of Beaumont Glacier, provide the first evidence of dated structural control on emplacement of the […]

Influence of adult breeding experience on growth and provisioning of Wandering Albatross Diomedea exulans chicks at South Georgia
Read more of: Influence of adult breeding experience on growth and provisioning of Wandering Albatross Diomedea exulans chicks at South GeorgiaFor most seabirds, reproductive performance improves with age; in albatrosses this is thought not to be so (experience being acquired before starting breeding) but only one study (of chick growth […]

Status of white-chinned petrels Procellaria aequinoctialis Linnaeus 1758, at Bird Island, South Georgia
Read more of: Status of white-chinned petrels Procellaria aequinoctialis Linnaeus 1758, at Bird Island, South GeorgiaThe white-chinned petrel (Procellaria aequinoctialis) is an abundant, widespread petrel breeding in tussock grassland at sub-Antarctic islands. Over the last decade it has been killed in large numbers in temperate […]

The use of acoustics to monitor burrow-nesting white-chinned petrels Procellaria aequinoctialis at Bird Island, South Georgia
Read more of: The use of acoustics to monitor burrow-nesting white-chinned petrels Procellaria aequinoctialis at Bird Island, South GeorgiaTape recordings of two types of vocalisations were used to assess burrow occupancy by white-chinned petrels (Procellaria aequinoctialis) at South Georgia. Birds responded to the rattle call on 74% of […]

Anomalous temperatures in central Scotia Sea sediments – Bottom water variation or pore water circulation in old ocean crust
Read more of: Anomalous temperatures in central Scotia Sea sediments – Bottom water variation or pore water circulation in old ocean crustWe report low temperature gradients (from 60% to 12% of geothermal), and extrapolated temperatures offset from modern bottom water temperatures, in sediments from the central Scotia Sea. We examine possible […]

Surface phosphomonoesterase activity of a natural immobilized system: Chroococcidioposis in an Antarctic desert rock
Read more of: Surface phosphomonoesterase activity of a natural immobilized system: Chroococcidioposis in an Antarctic desert rockThe phosphomonoesterase activity of a microbialcommunity dominated by Chroococcidiopsis in arock sample from the Antarctic dry desert was comparedwith that of a non-axenic culture of thecyanobacterium isolated from the same […]
