Raman spectroscopic studies of Antarctic endoliths and epiliths
Antarctica has long been recognised as a putative analogue for Mars’ past (1) and any life there is surviving in extreme conditions. Raman spectroscopy has been proved as a suitable […]

Recent variations in surface mass balance of the Antarctic Peninsula ice sheet
Read more of: Recent variations in surface mass balance of the Antarctic Peninsula ice sheetOver the period 1972-98 the height of the snow surface at eight Antarctic sites in Palmer Land and on Alexander Island has been measured with respect to fixed points on […]

Segregation of foraging between two sympatric penguin species: does rate maximisation make the difference?
Read more of: Segregation of foraging between two sympatric penguin species: does rate maximisation make the difference?Macaroni Eudyptes chrysolophus and gentoo Pygoscelis papua penguins occur sympatrically at Bird Island (54degrees00’S, 38degrees02’W), South Georgia, and have a similar diet. Macaroni penguins forage at shallower depths and further […]

Extreme sensitivity of biological function to temperature in Antarctic marine species
Read more of: Extreme sensitivity of biological function to temperature in Antarctic marine species1. Biological capacities to respond to changing environments dictate success or failure of populations and species over time. The major environmental feature in this context is often temperature, and organisms […]

The behavioral basis for nonlinear functional responses and optimal foraging in antarctic fur seals
Read more of: The behavioral basis for nonlinear functional responses and optimal foraging in antarctic fur sealsThis study investigated the degree to which the behavior of a predator in the marine environment can be used to indicate the availability of prey. It examined this in Antarctic […]

Metamorphic and thermal history of a fore-arc basin: the Fossil Bluff Group, Alexander Island, Antarctica
Read more of: Metamorphic and thermal history of a fore-arc basin: the Fossil Bluff Group, Alexander Island, AntarcticaThe Himalia Ridge Formation (Fossil Bluff Group), Alexander Island is a 2.2-km-thick sequence of Upper Jurassic-Lower Cretaceous conglomerates, sandstones and mudstones, derived from an andesitic volcanic arc and deposited in […]

Impact of the 1997/98 ENSO on upper ocean characteristics in Marguerite Bay, western Antarctic Peninsula
Read more of: Impact of the 1997/98 ENSO on upper ocean characteristics in Marguerite Bay, western Antarctic Peninsula[ 1] A year-round sequence of hydrographic casts is used to trace the evolution of the upper ocean waters in Marguerite Bay, western Antarctic Peninsula (wAP), between 1998 and 2002.

Monitoring the plasmapause using geomagnetic field line resonances
Read more of: Monitoring the plasmapause using geomagnetic field line resonancesThis paper discusses the use of ground magnetometer data to derive plasma mass density profiles of the dayside plasmapause region with spatial and temporal resolution in the range 0.15-0.4 R-E […]

Precipitation over the interior East Antarctic Ice Sheet related to midlatitude blocking-high activity
Read more of: Precipitation over the interior East Antarctic Ice Sheet related to midlatitude blocking-high activityIntermittent atmospheric blocking-high activity in the South Tasman Sea is shown to play a key role in delivering substantial snowfall as far south as at least 75degreesS on the central […]

Riverine habitat preferences of botos (Inia geoffrensis) and tucuxis (Sotalia fluviatilis) in the central Amazon
Read more of: Riverine habitat preferences of botos (Inia geoffrensis) and tucuxis (Sotalia fluviatilis) in the central AmazonThe distribution and density of the Amazon’s two contrasting endemic dolphins-boto, or Amazon river dolphin, Inia geoffrensis, and tucuxi, Sotalia fluviatilis-were examined on two adjoining large rivers in western Brazil.
