the granites of northern Patagonia and the Gastre Fault System in relation to the break -up of Gondwana
Read more of: the granites of northern Patagonia and the Gastre Fault System in relation to the break -up of GondwanaThe transcurrent Gastre Fault System in central Patagonia, which is closely associated with subvolcanic granite emplacement, is recognized as a major dextral shear-zone and geological boundary. We propose its equivalence […]

The respiratory system of the femaleVarroa jacobsoni (Oudemans): its adaptations to a range of environmental conditions
Read more of: The respiratory system of the femaleVarroa jacobsoni (Oudemans): its adaptations to a range of environmental conditionsThe morphology of the respiratory system of the femaleVarroa jacobsoni (Oudemans, 1904) is described. The mobile, appendage-like, emergent peritreme may be ‘raised’ to lie against the ventral integument or ‘lowered’ […]

Late quaternary changes in Antarctic bottom water velocity inferred from sediment grain size in the northern Weddell Sea
Read more of: Late quaternary changes in Antarctic bottom water velocity inferred from sediment grain size in the northern Weddell SeaNewly formed bottom water (θ ≤ −0.7°C) in the northern Weddell Sea flows E or NE at speeds up to 10–15 cm/s, with velocity decreasing towards the centre of the […]

Antarctic Marine Primary Production, Biogeochemical Carbon Cycles and Climatic Change [and Discussion]
Read more of: Antarctic Marine Primary Production, Biogeochemical Carbon Cycles and Climatic Change [and Discussion]In the Southern Ocean, inorganic macronutrients are very rarely depleted by phytoplankton growth. This has led to speculation on possible additional CO2 drawdown in this region. However, the effects of […]

Satellite tracking of wandering albatrosses (Diomedea exulans) in the South Atlantic
Read more of: Satellite tracking of wandering albatrosses (Diomedea exulans) in the South AtlanticThe movements of two wandering albatrosses, one of each sex, breeding at South Georgia, were tracked using satellite telemetry, particularly to assess whether such birds could be at risk from […]

Maximum dive depths attained by South Georgia diving petrel Pelecanoides georgicus at Bird Island, South Georgia
Read more of: Maximum dive depths attained by South Georgia diving petrel Pelecanoides georgicus at Bird Island, South GeorgiaMaximum dive depths have been recorded for a number of sea-bird species using simple lightweight capillary gauges (Burger & Wilson 1988). So far these studies have been confined to penguins […]
