The summer zooplankton community at South Georgia: biomass, vertical migration and grazing
Read more of: The summer zooplankton community at South Georgia: biomass, vertical migration and grazingZooplankton 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 […]

The propagation characteristics and Landau damping of Jovian whistlers in the Io torus
Read more of: The propagation characteristics and Landau damping of Jovian whistlers in the Io torusThe 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 […]

Redescription of Charcotia granulosa Vayssiere, 1906 (Nudibranchia: Arminoidea: Charcotiidae) from Signy Island, Antarctica
Read more of: Redescription of Charcotia granulosa Vayssiere, 1906 (Nudibranchia: Arminoidea: Charcotiidae) from Signy Island, AntarcticaThe 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 […]

Subglacial and seabed topography, ice thickness and water column thickness in the vicinity of Filchner-Ronne-Schelfseis, Antarctica
Read more of: Subglacial and seabed topography, ice thickness and water column thickness in the vicinity of Filchner-Ronne-Schelfseis, AntarcticaThe 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 […]

Tidal flexure at ice shelf margins
Read more of: Tidal flexure at ice shelf marginsHinge 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 […]

Small-scale convection at the interface between stratified layers of mafic and silicic magma, Campbell Ridges, NW Palmer Land, Antarctic Peninsula: Syn-magmatic way-up criteria
Read more of: Small-scale convection at the interface between stratified layers of mafic and silicic magma, Campbell Ridges, NW Palmer Land, Antarctic Peninsula: Syn-magmatic way-up criteriaExperimental 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 […]
