Abstract:
The dataset compiles sea-ice biomarkers (IP25, HBI II, HBI III, Triene E, Brassicasterol, Campesterol, Cholesterol, β- sitosterol) together with benthic and planktonic foraminiferal geochemistry (U/Ca, Mn/Ca, U/Mn, Mg/Ca) and benthic foraminiferal assemblage counts from Integrated Ocean Drilling Program Site U1343 in the eastern Bering Sea. The dataset covers the time range from 7.6-42 ka.
