MD01-2414 sedimentary sterol and elementary analysis dataset

This study investigates six phytosterols (β-sitosterol, stigmasterol, campesterol, dinosterol, epi-brassicasterol, and 24-methylene cholesterol) from core MD01-2414 in the central Okhotsk Sea, covering the past 1.5 million years. These sterols, produced by various organisms, serve as proxies for terrestrial and marine productivity in the central Okhotsk Sea and northeast Siberia.
