A suite of Early Jurassic metaluminous to strongly peraluminous granitoids occupy a rear-arc position in Palmer Land, Antarctic Peninsula with respect to a Mesozoic–Cenozoic magmatic arc. Fractional crystallization of a […]
The distribution of zooplankton as indicated by acoustic backscatter was compared with that of the phytoplankton biomass, with the degree of the shading caused by the presence of the bloom, […]
An account is given of one Austral summer’s experience of forecasting for flying activities and marine operations around the Antarctic Peninsula. Data available included surface and upper-air observations, analyses and […]
Zooplankton abundance and biomass were determined during January 1990 at two stations to the north-west of South Georgia using a Longhurst Hardy Plankton Recorder (LHPR). At both shelf and oceanic […]
Egg production in three species of calanoid copepods Rhincalanus gigas, Calanoides acutus and Calanus simillimus was investigated via incubations of females and recovery of eggs from net hauls made around […]
Müller Ice Shelf (67°15′S, 66°52′W) is situated at the southern end of Lallemand Fjord. It is a small ice shelf (∼80 km2) fed by Brückner and Antevs glaciers, which both […]
The propagation characteristics and path-integrated gain of Jovian lightning-generated whistlers are explored using the HOTRAY code. All waves are launched into the magnetosphere from just above the density peak in […]
Several species of nudibranch molluscs are abundant amongst the rich benthic hard substratum communities found close to the British Antarctic Survey base at Signy Island, in the Atlantic sector of […]
The nudibranch Charcotia granulosa, described originally by Vayssière (1906) from one specimen, was recollected for the first time at Signy Island, Antarctica. These three specimens allow a redescription of the […]
The seabed morphology beneath the ice shelf is dominated by a slope down towards the interior of the continent. Deep troughs, possibly glacially deepened, run beneath the eastern and weatern […]
