Biological sampling
The essential aim of biological sampling is to obtain samples that are representative of the targets under consideration. Sampling in support of in situ target strength studies should be aimed […]

Size at sexual maturity of Patagonian toothfish (Dissostichus eleginoides)
Read more of: Size at sexual maturity of Patagonian toothfish (Dissostichus eleginoides)Analyses of size at sexual maturity were undertaken on samples of Patagonian toothfish (Dissostichus eleginoides) caught in the commercial fishery within Subarea 48.3. The results for 1996 indicate that Lm50 […]

Life-history consequences of predation for a subantarctic beetle: evaluating the contribution of direct and indirect effects
Read more of: Life-history consequences of predation for a subantarctic beetle: evaluating the contribution of direct and indirect effects1. Recently, a small predatory beetle, Trechisibus antarcticus (Carabidae), was accidentally introduced onto the island of South Georgia, sub-Antarctic. 2. From the presumed site of introduction the beetle is invading […]

FT-Raman spectroscopy of avian mummified tissue of archaeological relevance
Read more of: FT-Raman spectroscopy of avian mummified tissue of archaeological relevanceThere are frequent reports of mummified seals in the cold deserts of Antarctica. However, a mummified penguin found over 100 miles from the coast and at an altitude of 600 […]

Comparative Raman microscopy of a Martian meteorite and Antarctic lithic analogues
Read more of: Comparative Raman microscopy of a Martian meteorite and Antarctic lithic analoguesThe Raman microspectra of the Nakhla SNC meteorite, which probably originates from Mars, are reported here for the first time. The specimen is shown to be heterogeneous, even at a […]

Implications of the oceanic thermal skin temperature deviation at high wind speed
Read more of: Implications of the oceanic thermal skin temperature deviation at high wind speedExtensive oceanographic and atmospheric observations obtained during three independent experiments in the Atlantic Ocean are used to demonstrate the relationship between wind speed and the temperature deviation ΔT, which is […]

The impact of tourists on Antarctic tardigrades: an ordination-based model
Read more of: The impact of tourists on Antarctic tardigrades: an ordination-based modelTardigrades are important members of the Antarctic biota yet little is known about their role in the soil fauna or whether they are affected by anthropogenic factors. The German Federal […]

Walvis Ridge barrier: its influence on palaeoenvironments and source rock generation deduced from ostracod distributions in the early South Atlantic Ocean
Read more of: Walvis Ridge barrier: its influence on palaeoenvironments and source rock generation deduced from ostracod distributions in the early South Atlantic OceanThe early South Atlantic was subdivided latitudinally by the proto-Walvis Ridge, which separated early Cretaceous open marine conditions in the south from non-marine environments to the north. Changes in the […]

The elemental and biochemical composition of bryophytes from the maritime Antarctic
Read more of: The elemental and biochemical composition of bryophytes from the maritime AntarcticThe elemental and biochemical composition of eight moss species from the maritime Antarctic were determined fornightly (summer) or monthly (winter) from December 1992 to November 1994. Short-duration summer carbohydrate maxima […]

A new diffusion matrix for whistler mode chorus waves
Read more of: A new diffusion matrix for whistler mode chorus wavesGlobal models of the Van Allen radiation belts usually include resonant wave-particle interactions as a diffusion process, but there is a large uncertainty over the diffusion rates. Here we present […]

Middle Cambrian rift-related volcanism in the Ellsworth Mountains, Antarctica: tectonic implications for the palaeo-Pacific margin of Gondwana
Read more of: Middle Cambrian rift-related volcanism in the Ellsworth Mountains, Antarctica: tectonic implications for the palaeo-Pacific margin of GondwanaThe Ellsworth Mountains of West Antarctica represent part of a displaced terrane once situated along the palaeo-Pacific margin of Gondwana, prior to supercontinent break-up, adjacent to South Africa and the […]

Late Cambrian stratigraphy of the Heritage Range, Ellsworth Mountains: implications for basin evolution
Read more of: Late Cambrian stratigraphy of the Heritage Range, Ellsworth Mountains: implications for basin evolutionDeposition of the Upper Cambrian succession of the Ellsworth Mountains was influenced by major, episodic tectonically-driven changes to the depositional basin geometry. We subdivide the succession into four stratigraphical sequences […]
