Stable isotope and Cd/Ca ratios of Neogloboquadrina pachyderma in high-latitude sediments ...
Recent studies have stressed the role of high latitude nutrient levels and productivity in controlling the carbon isotopic composition of the deep sea and the CO2 content of the atmosphere. We undertook a study of the chemical composition of the polar planktonic foraminifer Neogloboquadrina pachyder...

Recent studies have stressed the role of high latitude nutrient levels and productivity in controlling the carbon isotopic composition of the deep sea and the CO2 content of the atmosphere. We undertook a study of the chemical composition of the polar planktonic foraminifer Neogloboquadrina pachyderma (s., sinistral coiling) from 30 late Holocene samples and 49 down core records from the high-latitude North and South Atlantic Oceans to evaluate the history of sea surface chemical change from glacial to interglacial time. Stable isotopic analysis of coretop samples from the Atlantic, Pacific and Southern Oceans shows no significant correlation between the delta13C of N. pachyderma and either delta13C or PO4 in seawater. Conversely, Cd/Ca ratios in planktonic foraminifera are consistent with the PO4 content of surface waters. The level of maximum glaciation (18,000 yr B.P.), identified by CLIMAP and delta18O, was chosen for mapping.
