Investigation of the Sea-Surface Temperature Ice Volume Connection in the 41 KYR World

Investigators

Abstract

This project will generate data on alkenone unsaturation (as an indicator of sea surface temperature) and benthic 18 O (as an indicator of ice volume) in north/south transects of sediment cores from the Pacific and Atlantic Oceans spanning intervals of the late and middle Pleistocene. The goal is to compare the spectral relations of SST, ice volume and surface radiation from orbital variations under different climate regimes.
