The calcareous nannofossil assemblages from sediment core DS97-2P from the Reykjanes Ridge have been investigated to document oceanographic changes in surface water during the...
A planktonic foraminiferal fauna of probable late Aptian age is recorded in Cores 113-693A-47R and -48R, located on the Antarctic continental margin. Moderate to highly productive surface waters and u
We use biogenic silica (opal) mass accumulating rates (MARs) at Ocean Drilling Program Site 745B to infer upwelling, and by extension upper water column stratification, on glacial to interglacial time
