Sensitivity of the divide position at Siple Dome, West Antarctica to boundary forcing
Read more of: Sensitivity of the divide position at Siple Dome, West Antarctica to boundary forcingA linearized perturbation about a two-dimensional Vialov-Nye icesheet profile is used to investigate the sensitivity of the divide position at Siple Dome, West Antarctica, to small changes in the accumulation […]

Interannual variability of the South Georgia marine ecosystem: biological and physical sources of variation in the abundance of krill
Read more of: Interannual variability of the South Georgia marine ecosystem: biological and physical sources of variation in the abundance of krillInterannual variability is a characteristic feature of the Southern Ocean ecosystem, yet the relative roles of biological and physical processes in generating these fluctuations are unknown. There is now extensive […]

Carbon flux in ice–ocean–plankton systems of the Bellingshausen Sea during a period of ice retreat
Read more of: Carbon flux in ice–ocean–plankton systems of the Bellingshausen Sea during a period of ice retreatMost analyses of marine microbial systems in the seasonally ice covered areas of the Southern Ocean have been based on data from the major embayment areas of the Ross and […]

Postdepositional change in snowpack nitrate from observation of year-round near-surface snow in coastal Antarctica
Read more of: Postdepositional change in snowpack nitrate from observation of year-round near-surface snow in coastal AntarcticaPostdepositional loss of nitrate in near-surface snowfall is well known, with mean levels of nitrate in ice cores of around 20 to 80 ng g−1, while nitrate in surface snow […]

Identification and correlation of distal tephra layers in deep-sea sediment cores, Scotia Sea, Antarctica
Read more of: Identification and correlation of distal tephra layers in deep-sea sediment cores, Scotia Sea, AntarcticaQuaternary deposits in six sediment cores from the Scotia Sea, Antarctica, were examined for the presence of volcanic ash layers. The cores were recovered from water depths of 3369-4025 m. […]

Profiles of soluble carbohydrates and their adaptive role in maritime Antarctic terrestrial arthropods
Read more of: Profiles of soluble carbohydrates and their adaptive role in maritime Antarctic terrestrial arthropodsThe existence of seasonal changes in concentrations of water-soluble carbohydrates in arthropods (both freezing-tolerant and intolerant species) from Signy Island was demonstrated. Seasonal patterns of variation, imposed by seasonality of […]

Spiess Ridge: An axial high on the slow spreading Southwest Indian Ridge
Read more of: Spiess Ridge: An axial high on the slow spreading Southwest Indian RidgeWe report recent mapping of Spiess Ridge with the Hawaii-MR1 sidescan sonar. Spiess Ridge is an unusual elongate 90 by 50 km volcanic feature on the slow spreading Southwest Indian […]

The present configuration of the Bouvet triple junction
Read more of: The present configuration of the Bouvet triple junctionNew Hawaii-MR1 sonar data show that the southernmost Mid-Atlantic Ridge joins the South American–Antarctic Ridge by an obliquely opening rift and overlaps Spiess Ridge, the westernmost segment of the Southwest […]
