Abstract:

A dataset of 42 collected surface sediment samples from the East Siberian Sea by analysis of Arctic sea ice (IP25) and open water phytoplankton biomarkers (Brassicasterol, Dinosterol, HBI-III and HBI-IV). Terrigenous sterols (campesterol and β-sitosterol) data in this region are also included in the dataset. All biomarkers are based on TOC calculations.
