The influence of ice scour on benthic communities at three contrasting sites at Adelaide Island, Antarctica
Read more of: The influence of ice scour on benthic communities at three contrasting sites at Adelaide Island, AntarcticaIce scouring is a key structuring force acting on high latitude shallow benthic communities. Despite its importance, detailed studies of scoured communities are still rare. Here we report the ecological […]

Ice disturbance intensity structures benthic communities in nearshore Antarctic waters
Read more of: Ice disturbance intensity structures benthic communities in nearshore Antarctic watersIce scouring is one of the 5 most significant natural forces acting on ecosystems, yet very few data exist linking the intensity of ice disturbance with parameters of benthic community […]

Late Glacial history of the Ross Sea sector of the West Antarctic Ice Sheet: evidence from englacial layering at Talos Dome, East Antarctica
Read more of: Late Glacial history of the Ross Sea sector of the West Antarctic Ice Sheet: evidence from englacial layering at Talos Dome, East AntarcticaThe timing of West Antarctic Ice Sheet (WAIS) expansion and retreat during the last glacial cycle is crucial to evaluating the processes controlling ice sheet fluctuations. There is currently debate […]

Synchronisation of the EDML and EDC ice cores for the last 52 kyr by volcanic signature matching
Read more of: Synchronisation of the EDML and EDC ice cores for the last 52 kyr by volcanic signature matchingA common time scale for the EPICA ice cores from Dome C (EDC) and Dronning Maud Land (EDML) has been established. Since the EDML core was not drilled on a […]

Rich and rare – first insights into species diversity and abundance of Antarctic abyssal Gastropoda (Mollusca)
Read more of: Rich and rare – first insights into species diversity and abundance of Antarctic abyssal Gastropoda (Mollusca)The abyssal depths of the polar oceans are thought to be low in diversity compared with the shallower polar shelves and temperate and tropical deep-sea basins. Our recent study on […]
