A global picture of the first abrupt climatic event occurring during the last glacial inception
Read more of: A global picture of the first abrupt climatic event occurring during the last glacial inceptionThe orbital-scale transition from the last interglacial to glacial climate corresponds to the progressive organization of global millennial-scale climate variability. Here, we investigate the structure and the global fingerprint of […]

Slow arm regeneration in the Antarctic brittle star Ophiur crassa (Echinodermata, Ophiuroidea)
Read more of: Slow arm regeneration in the Antarctic brittle star Ophiur crassa (Echinodermata, Ophiuroidea)Regeneration of arms in brittle stars is thought to proceed slowly in low temperature environments. Here a survey of natural arm damage and arm regeneration rates is documented in the […]

Forecasting the radiation belts in Europe
Read more of: Forecasting the radiation belts in EuropeWeather forecasting has expanded to space weather. As of 1 March 2012, satellite operators and the general public will be able to obtain forecasts of the Earth’s radiation belts, thanks […]

Dynamical processes involved in the retreat of marine ice sheets
Read more of: Dynamical processes involved in the retreat of marine ice sheetsMarine ice sheets with mechanics described by the shallow-ice approximation by definition do not couple mechanically with the shelf. Such ice sheets are known to have neutral equilibria. We consider […]

Centurial‐millenial ice‐rafted debris pulses from ablating marine ice sheets
Read more of: Centurial‐millenial ice‐rafted debris pulses from ablating marine ice sheetsWe use an ice‐sheet model to show that (i) margins of marine ice‐sheets can be expected to be frozen to the bed, except where ice‐streams discharge; (ii) 20–50km retreats induced […]

Early East Antarctic Ice Sheet growth recorded in the landscape of the Gamburtsev Subglacial Mountains
Read more of: Early East Antarctic Ice Sheet growth recorded in the landscape of the Gamburtsev Subglacial MountainsThe Gamburtsev Subglacial Mountains are regarded as a key nucleation site for the Antarctic Ice Sheet and they retain a unique long-term record of pre-glacial and early glacial landscape evolution. […]

Subglacial melt channels and fracture in the floating part of Pine Island Glacier, Antarctica
Read more of: Subglacial melt channels and fracture in the floating part of Pine Island Glacier, AntarcticaA dense grid of ice-penetrating radar sections acquired over Pine Island Glacier, West Antarctica has revealed a network of sinuous subglacial channels, typically 500 m to 3 km wide, and […]

Chrono- and lithostratigraphy of a Mesozoic–Tertiary fore- to intra-arc basin: Adelaide Island, Antarctic Peninsula
Read more of: Chrono- and lithostratigraphy of a Mesozoic–Tertiary fore- to intra-arc basin: Adelaide Island, Antarctic PeninsulaThe Mesozoic fore-arc of the Antarctic Peninsula is exposed along its west coast. On Adelaide Island, a 2–3 km succession of turbiditic coarse sandstones and volcanic rocks is exposed. Four […]

An unusual hermaphrodite reproductive trait in the Antarctic brooding bivalve Lissarca miliaris (Philobryidae) from the Scotia Sea, Southern Ocean
Read more of: An unusual hermaphrodite reproductive trait in the Antarctic brooding bivalve Lissarca miliaris (Philobryidae) from the Scotia Sea, Southern OceanThe Antarctic marine environment is extreme in its low temperatures and short periods of primary productivity. Invertebrates must therefore adapt to maximise reproductive output where low temperature and limited food […]
