Variation in plasma leptin levels in response to fasting in Antarctic fur seals (Arctocephalus gazella)
Read more of: Variation in plasma leptin levels in response to fasting in Antarctic fur seals (Arctocephalus gazella)Plasma leptin levels were determined in 8 lactating female and 20 pup Antarctic fur seals (Arctocephalus ga:ella) during fasting periods of normal duration. Plasma leptin levels ranged from 1.35-3.19 ng.ml(-1) […]

Influence of magnetospheric processes on winter HF radar spectra characteristics
Read more of: Influence of magnetospheric processes on winter HF radar spectra characteristicsThis study investigates further the relationship between regions of the magnetosphere and the characteristics of HF radar Doppler spectra recorded in the ionospheric projection of those regions. It builds on […]

Modelling multivariate determinants of growth in Antarctic bryozoans
Read more of: Modelling multivariate determinants of growth in Antarctic bryozoansBryozoans seem fairly typical amongst Antarctic benthos, in both timing and magnitude of growth. Growth varies interspecifically from nearly comparable to much slower than warm water equivalent species. Factors including […]

Distribution of juvenile squid in the Scotia Sea in relation to regional oceanography
Read more of: Distribution of juvenile squid in the Scotia Sea in relation to regional oceanographyA total of 211 juvenile and paralarval squid were collected on five research cruises made in the Scotia Sea region during the austral summer (1996-1999). These included specimens of Alluroteuthis […]

The fossil record of Limopsis (Bivalvia: Limopsidae) in Antarctica and the southern high latitudes
Read more of: The fossil record of Limopsis (Bivalvia: Limopsidae) in Antarctica and the southern high latitudesLimopsis is one of the most speciose and widespread bivalve genera in the Southern Ocean at the present day. However, the fossil record of the genus is poorly known from […]

Seasonal evolution of the upper-ocean adjacent to the South Orkney Islands, Southern Ocean: results from a “lazy biological mooring”.
Read more of: Seasonal evolution of the upper-ocean adjacent to the South Orkney Islands, Southern Ocean: results from a “lazy biological mooring”.A serendipitous > 8-month time series of hydrographic properties was obtained from the vicinity of the South Orkney Islands, Southern Ocean, by tagging a southern elephant seal (Mirounga leonine) on […]

Flow at ice-divide triple junctions: 2. Three-dimensional views of isochrone architecture from ice-penetrating radar surveys
Read more of: Flow at ice-divide triple junctions: 2. Three-dimensional views of isochrone architecture from ice-penetrating radar surveysGround-based surveys of ice-divide triple junctions in two Antarctic ice rises, the Fletcher Promontory and Berkner Island, have been carried out using low-frequency ice-penetrating radars. These surveys have focused on […]

Interglacial and glacial variability from the last 800 ka in marine, ice and terrestrial archives
Read more of: Interglacial and glacial variability from the last 800 ka in marine, ice and terrestrial archivesWe have compiled 37 ice, marine and terrestrial palaeoclimate records covering the last 800 000 years in order to assess the pattern of glacial and interglacial strength, and termination amplitude. […]

Chorus-driven resonant scattering of diffuse auroral electrons in nondipolar magnetic fields
Read more of: Chorus-driven resonant scattering of diffuse auroral electrons in nondipolar magnetic fieldsWe perform a comprehensive analysis of resonant scattering of diffuse auroral electrons by oblique nightside chorus emissions present along a field line with an equatorial crossing of 6 R(E) at […]

Food for thought: risks of non-native species transfer to the Antarctic region with fresh produce
Read more of: Food for thought: risks of non-native species transfer to the Antarctic region with fresh produceTo understand fully the risk of biological invasions, it is necessary to quantify propagule pressure along all introduction pathways. In the Antarctic region, importation of fresh produce is a potentially […]

Particle size measurement of diatoms with inference of their properties: comparison of three techniques
Read more of: Particle size measurement of diatoms with inference of their properties: comparison of three techniquesDiatom-rich sediments are common in several oceanic regions, especially the Southern Ocean. Some of these are strongly affected by bottom currents and are expected to be sorted by the flow. […]
