Earth & Environment / CLIMATE CHANGE
Surface and Deep Water Processes were Closely Related during Abrupt Change in the North Atlantic over the Past 420000 Years
24 Aug, 2007 11:50 am

A recent study (Martrat et al., 2007) based on high-resolution analyses of proxies for sea surface temperature, water mass distribution and relative biomarker content in marine sediment cores from the Iberian Margin shows that centennial climate variability over the last ice age exhibited a clear bipolar behaviour over the last 420,000 years. Abrupt cold episodes also occurred after relatively warm and largely ice-free periods when the predominance changed from northern deep waters to southern.... Read more
