Genomics: applications to Antarctic ecosystems
Biological research in Antarctica has made considerable progress in science over recent decades. As little as 50 years ago, there was scant knowledge even of the species inhabiting the region. […]

Foraging and provisioning strategies of the light-mantled sooty albatross at South Georgia: competition and co-existence with sympatric pelagic predators
Read more of: Foraging and provisioning strategies of the light-mantled sooty albatross at South Georgia: competition and co-existence with sympatric pelagic predatorsForaging and provisioning strategies of the light-mantled sooty albatross (LMSA) Phoebetria palpebrata were studied during chick-rearing at Bird Island, South Georgia, in January to May 2003. Virtually all trips of […]

Summer distribution and migration of nonbreeding albatrosses: individual consistencies and implications for conservation
Read more of: Summer distribution and migration of nonbreeding albatrosses: individual consistencies and implications for conservationMany birds show a surprising degree of intraspecific variability in migratory tendency and choice of wintering site. In this study, we tracked the seasonal movements of 35 nonbreeding Black-browed Albatrosses […]

A multi-proxy approach to determine Antarctic terrestrial palaeoclimate during the Late Cretaceous and Early Tertiary
Read more of: A multi-proxy approach to determine Antarctic terrestrial palaeoclimate during the Late Cretaceous and Early TertiaryFossil wood is abundant throughout the Cretaceous and Tertiary sequences of the northern Antarctic Peninsula region. The fossil wood represents the remains of the vegetation that once grew at the […]

Glacier surge dynamics of Sortebræ, east Greenland, from synthetic aperture radar feature tracking
Read more of: Glacier surge dynamics of Sortebræ, east Greenland, from synthetic aperture radar feature trackingWe have measured the surface flow rate of the large east Greenland glacier, Sortebræ, through both the initiation and termination of a major surge using synthetic aperture radar (SAR) feature […]

The International Polar Year 2007–2008: planning for a new phase of polar exploration and understanding
Read more of: The International Polar Year 2007–2008: planning for a new phase of polar exploration and understandingThe concept of the International Polar Year (IPY) 2007–2008 is of an intensive burst of internationally coordinated, interdisciplinary, scientific research and observations focused on the Earth’s Polar Regions. The research […]

Deconvolution-based resolution enhancement of chemical ice core records obtained by continuous flow analysis
Read more of: Deconvolution-based resolution enhancement of chemical ice core records obtained by continuous flow analysisContinuous flow analysis (CFA) has become a popular measuring technique for obtaining high-resolution chemical ice core records due to an attractive combination of measuring speed and resolution. However, when analyzing […]

Tidal exchange of zooplankton between Lough Hyne and the adjacent coast
Read more of: Tidal exchange of zooplankton between Lough Hyne and the adjacent coastPlankton samples collected in November 2002, February, May and August 2003 were used to examine seasonal variation in tidal exchange of zooplankton biomass, abundance and species composition between Lough Hyne […]

On the relationship between surface and basal properties on glaciers, ice sheets, and ice streams
Read more of: On the relationship between surface and basal properties on glaciers, ice sheets, and ice streamsThe influence of basal disturbances on the steady state surface topography and on surface velocities of glaciers and ice sheets is investigated numerically. This is done for finite amplitude basal […]

Causes of offspring mortality in the Antarctic fur seal, Arctocephalus gazella: the interaction of density dependence and ecosystem variability
Read more of: Causes of offspring mortality in the Antarctic fur seal, Arctocephalus gazella: the interaction of density dependence and ecosystem variabilityRates of pup production and causes of pup mortality, recorded in a designated study colony on Bird Island, South Georgia, from 1989 to 2003, were used to evaluate the factors […]
