The Pliocene (c. 5.3 - 1.8 Myr BP) was the last epoch of geological time in which global temperatures were generally higher than modern. It is important if we are…Read more on Characterizing ice sheets during the Pliocene: evidence from data and models
Glacial dynamics of the West Antarctic Ice Sheet in the southern Bellingshausen Sea during the last glacial cycle
1 January, 2007 by Claus-Dieter Hillenbrand, Robert Larter
A major glacial trough ("Belgica Trough") on the continental shelf in the southern Bellingshausen Sea acted as an important outlet for ice draining the West Antarctic Ice Sheet during the…The ice-rock interface

High-resolution airborne gravity imaging over James Ross Island (West Antarctica)
1 January, 2007 by Fausto Ferraccioli, Hugh Corr, Tom Jordan
James Ross Island (JRI) exposes a Miocene-Recent alkaline basaltic volcanic complex that developed in a back-arc, east of the northern Antarctic Peninsula. JRI has been the focus of several geological…Read more on High-resolution airborne gravity imaging over James Ross Island (West Antarctica)
Impact of climate change on Southern Ocean sink for CO2 and marine ecosystems
1 January, 2007
Marine ecosystems (here referring to plankton assemblages) play an important role in climate because they maintain the atmospheric concentration of CO2 at 200 ppm lower than it would be in…Read more on Impact of climate change on Southern Ocean sink for CO2 and marine ecosystems
