Concentrations and fluxes of the sea-ice biomarkers 2,6,10,14-Tetramethyl-7-(3-methylpent-4-enyl)pentadecane (IP25) and highly branched isoprenoid triene (HBI III) from marine sediment core AMD14-204_CASQ

Concentrations of the sea-ice biomarker IP25 and highly branched isoprenoid triene (HBI III) (ng/g), total organic carbon content (TOC; %), IP25 and HBI III concentrations normalized to TOC (ng/gTOC), and fluxes of IP25 and HBI III (ng/unit surface area/yr) from the marine sediment core AMD14-204_CASQ that was retrieved from the West Greenland shelf, offshore Upernavik, and which spans the last ca. 9,000 years.

本数据集涵盖采自西格陵兰陆架乌佩纳维克近海的海洋沉积物岩芯AMD14-204_CASQ的多指标地球化学数据，具体包括：海冰生物标志物IP25（sea-ice biomarker IP25）与高支链类异戊二烯烃三烯（HBI III）的浓度（单位：ng/g）、总有机碳（total organic carbon）含量（TOC，%）、经TOC标准化后的IP25与HBI III浓度（单位：ng/gTOC），以及IP25和HBI III的沉积通量（单位：ng/单位表面积/年）；该岩芯的沉积记录覆盖约过去9000年的时间跨度。
