The concentrations of the sea ice biomarker proxy IP25 (Ice Proxy with 25 carbon atoms) and two phytoplankton biomarkers (a tri-unsaturated highly branched isoprenoid (HBI) lipid (HBI III) and epi-brassicasterol) have been measured in surface sediments from West Svalbard. IP25 concentration exhibited a positive relationship with that of HBI III and epi-brassicasterol, suggesting that the rapidly fluctuating...
The Bering Sea, asa transition between the Arctic and the Pacific oceans, plays an important role in global climate change and biogeochemical cycles. Here we examined a variety of biomarkers in a core (BR07) from the northern continental slope of the Bering Sea in order to reconstruct summer sea surface temperature (SST) and sea ice extent during the period 11–2ka (thousands of calendar years ago)...
