Growth, age structure and environmental history in the cephalopod Martialia hyadesi (Teuthoidea: Ommastrephidae) at the Antarctic Polar Frontal Zone and on the Patagonian Shelf Edge
Read more of: Growth, age structure and environmental history in the cephalopod Martialia hyadesi (Teuthoidea: Ommastrephidae) at the Antarctic Polar Frontal Zone and on the Patagonian Shelf EdgeMartialia hyadesi were collected from fishing vessels at the Antarctic Polar Frontal Zone (APFZ) and the Patagonian Shelf Edge (PASE) during the 1989 austral autumn and winter. Squid were measured, […]

West Antarctic Ice Sheet retreat driven by Holocene warm water incursions
Read more of: West Antarctic Ice Sheet retreat driven by Holocene warm water incursionsGlaciological and oceanographic observations coupled with numerical models show that warm Circumpolar Deep Water (CDW) incursions onto the West Antarctic continental shelf cause melting of the undersides of floating ice […]

Bacterial communities associated with the Southern Ocean vent gastropod, Gigantopelta chessoia: indication of horizontal symbiont transfer
Read more of: Bacterial communities associated with the Southern Ocean vent gastropod, Gigantopelta chessoia: indication of horizontal symbiont transferRecently discovered hydrothermal vents of the East Scotia Ridge (ESR) in the Southern Ocean host unique faunal communities that depend on microbial chemosynthetic primary production. These highly abundant invertebrates gain […]

Equatorward propagating auroral arcs driven by ULF wave activity: Multipoint ground- and space-based observations in the dusk sector auroral oval
Read more of: Equatorward propagating auroral arcs driven by ULF wave activity: Multipoint ground- and space-based observations in the dusk sector auroral ovalObservations of multiple equatorward propagating arcs driven by a resonant Alfvén wave on closed field lines are presented. Data sets from the European Incoherent Scatter Svalbard Radar (ESR) and Meridian […]

Utility and limits of biomass spectra: the nekton community sampled with the RMT 25 in the Scotia Sea during austral summer
Read more of: Utility and limits of biomass spectra: the nekton community sampled with the RMT 25 in the Scotia Sea during austral summerAn RMT 25 opening/closing net was used to sample the nekton community at 2 stations in the ice free zone (IFZ) of the Scotia Sea (Stn 1 approximately 10 nautical […]

Simultaneous two hemisphere observations of the presence of polar patches in the nightside ionosphere
Read more of: Simultaneous two hemisphere observations of the presence of polar patches in the nightside ionosphereThe presence of polar patches as observed simultaneously in the same magnetic meridian of opposite nightside ionospheres by coherent and incoherent scatter radars are described. The patches appear to be […]

A new mechanism for polar patch formation
Read more of: A new mechanism for polar patch formationPolar patches are regions within the polar cap where the F-region electron concentration and airglow emission at 630 nm are enhanced above a background level. Previous observations have demonstrated that […]
