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 […]
Hinge zones accommodate the differential tidal movement between floating ice shelves, which move with the sea tide, and grounded ice sheets, which do not. Observations on Rutford Ice Stream and […]
Experimental data suggest that some igneous mafic inclusions are formed at the interface between underlying mafic magma and more silicic magma in a reservoir by a process of gas exsolution […]
Evidence of short-lived episodes of mid-Cretaceous deformation, metamorphism, uplift, and hiatus in sedimentation is widespread in the Lower Cretaceous rocks that bordered the Cretaceous Pacific basin. I present a model […]
