Distribution, lithofacies and environmental context of Neogene glacial sequences on James Ross and Vega islands, Antarctic Peninsula
Read more of: Distribution, lithofacies and environmental context of Neogene glacial sequences on James Ross and Vega islands, Antarctic PeninsulaConsiderable controversy exists concerning the stability of the Antarctic Ice Sheet during the Neogene Period. The northern Antarctic Peninsula is in a critical position in this debate as it represents […]

Steep reverse bed slope at the grounding line of the Weddell Sea sector in West Antarctica
Read more of: Steep reverse bed slope at the grounding line of the Weddell Sea sector in West AntarcticaThe bed of the West Antarctic Ice Sheet is, in places, more than 1.5 km below sea level1, 2. It has been suggested that a positive ice-loss feedback may occur when […]

QBO modulation of traveling planetary waves during northern winter
Read more of: QBO modulation of traveling planetary waves during northern winterThis study analyzes geopotential height data from the ERA-40 and ERA-Interim reanalyses for the period of 1958–2009 to provide some new insights on the stratospheric Quasi-Biennial Oscillation (QBO) modulation of […]
