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 […]

Iheyaspira bathycodon new species (Vetigastropoda: Trochoidea: Turbinidae: Skeneinae) from the Von Damm Vent Field, Mid-Cayman Spreading Centre, Caribbean
Read more of: Iheyaspira bathycodon new species (Vetigastropoda: Trochoidea: Turbinidae: Skeneinae) from the Von Damm Vent Field, Mid-Cayman Spreading Centre, CaribbeanIheyaspira bathycodon sp. nov. is described from the Von Damm Vent Field on the world’s deepest spreading centre, the Mid-Cayman Spreading Centre (MCSC), Caribbean, at 2300 m depth. The new […]

End-to-end in Southern Ocean ecosystems
Read more of: End-to-end in Southern Ocean ecosystemsSouthern Ocean ecosystems matter for us all because they are important in Earth System processes and contribute to food security; they are also undergoing some of the most rapid changes […]

The Amundsen Sea and the Antarctic Ice Sheet
Read more of: The Amundsen Sea and the Antarctic Ice SheetA few decades ago, Antarctic ice sheets were expected to grow as the atmosphere warmed and increasing poleward moisture transport added snowfall to regions that would remain below freezing year-round. […]

Representation of the Antarctic Circumpolar Current in the CMIP5 climate models and future changes under warming scenarios
Read more of: Representation of the Antarctic Circumpolar Current in the CMIP5 climate models and future changes under warming scenariosThe representation of the Antarctic Circumpolar Current (ACC) in the fifth Coupled Models Intercomparison Project (CMIP5) is generally improved over CMIP3. The range of modeled transports in the historical (1976–2006) […]
