Influence of changing temperature on growth rate and competition between two psychrotolerant Antarctic bacteria: competition and survival in non-steady-state temperature environments
Read more of: Influence of changing temperature on growth rate and competition between two psychrotolerant Antarctic bacteria: competition and survival in non-steady-state temperature environmentsCompetition between two psychrotolerant bacteria was examined in glycerol-limited chemostat experiments subjected to non-steady-state conditions of temperature. One bacterium, a Brevibacterium sp. strain designated CR3/1/15, responded rapidly to temperature change, […]

Improvements to the accuracy of zenith-sky measurements of total ozone by visible spectrometers
Read more of: Improvements to the accuracy of zenith-sky measurements of total ozone by visible spectrometersVisible spectra of the zenith-sky were recorded at Faraday in Antartica (65°S) during 1990. Line-of-sight ozone amounts were deduced by fitting laboratory cross-sections to the spectra. At the lattitude of […]

Mapping unstable manifolds using drifters/floats in a Southern Ocean field campaign
Read more of: Mapping unstable manifolds using drifters/floats in a Southern Ocean field campaignIdeas from dynamical systems theory have been used in an observational field campaign in the Southern Ocean to provide information on the mixing structure of the flow. Instantaneous snapshops of […]

Using stars for remote sensing of the Earth’s stratosphere
Read more of: Using stars for remote sensing of the Earth’s stratosphereA new UV–visible spectrometer system that measures the absorption of light from stars and planets by constituents in the Earth’s atmosphere is described. Because it can be used to make […]

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 […]
