Crustal thickening along the West Antarctic Gondwana margin during mid-Cretaceous deformation of the Triassic intra-oceanic Dyer Arc
Read more of: Crustal thickening along the West Antarctic Gondwana margin during mid-Cretaceous deformation of the Triassic intra-oceanic Dyer ArcSubduction-related Mesozoic mafic dykes in eastern Palmer Land, Antarctic Peninsula, record the development of an intra-oceanic arc terrane, the Dyer Arc, probably of late Permian–Triassic age, represented by a tholeiitic […]

Albedo of the ice covered Weddell and Bellingshausen Seas
Read more of: Albedo of the ice covered Weddell and Bellingshausen SeasThis study investigates the surface albedo of the sea ice areas adjacent to the Antarctic Peninsula during the austral summer. Aircraft measurements of the surface albedo, which were conducted in […]

Differences in foraging behaviour and feeding ecology in giant petrels
Read more of: Differences in foraging behaviour and feeding ecology in giant petrelsThe two sibling species of giant petrels (northern Macronectes halli and the southern M. giganteus), the dominant scavengers of the sub-Antarctic and Antarctic environment, are one of the best examples […]

The annual and longitudinal variations in plasmaspheric ion density
Read more of: The annual and longitudinal variations in plasmaspheric ion densityThis paper shows that at solar maximum, equatorial ion densities at L = 2.5 are substantially higher at American longitudes in the December months than in the June months. This […]

Ecological drivers of change at South Georgia: the krill surplus, or climate variability
Read more of: Ecological drivers of change at South Georgia: the krill surplus, or climate variabilityMacaroni penguins Eudyptes chrysolophus are thought to be one of the most important mesopredators in the Southern Ocean having a greater impact on prey availability and abundance than any other […]

Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edge
Read more of: Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edgeWe surveyed Antarctic krill (Euphausia superba) under sea ice using the autonomous underwater vehicle Autosub-2. Krill were concentrated within a band under ice between 1 and 13 kilometers south of […]

FT-Raman spectroscopic analysis of an Antarctic endolith
Read more of: FT-Raman spectroscopic analysis of an Antarctic endolithThe FT-Raman spectra of an Antarctic endolith from the LTER site at Lake Hoare are reported. The specimen provides an unusual occurrence of endolithic colonization of an igneous rock substratum, […]
