Contents of Amino-Bacteriohopanepolyols in sediment core GeoB7702-3

This dataset contains abundances of Amino-Bacteriohopanepolyols (Amino-BHPs; bacterial biomarkers) in marine sediment core GeoB7702-3, continental margin off Israel/eastern Mediterranean Sea. The record covers the last 18,000 years. The compounds were analyzed by Ultra High Pressure Liquid Chromatography – Ultra High Resolution quadrupole time-of-flight tandem Mass Spectrometry (UHPLC – UHR-qTOF-MS). The data are presented as peak area and concentrations. Given the lack of appropriate standards for BHP-quantification, the concentrations are given in arbitrary units (peak area/µg sediment).

本数据集包含采自以色列以东地中海海域大陆边缘的海洋沉积物岩芯GeoB7702-3中的氨基细菌藿烷多醇（Amino-Bacteriohopanepolyols, Amino-BHPs；细菌生物标志物）丰度数据。该记录覆盖过去18000年的时间范围。所涉化合物通过超高压液相色谱-超高分辨率四极杆飞行时间串联质谱（UHPLC – UHR-qTOF-MS）完成分析。数据以峰面积与浓度形式呈现。鉴于缺乏适用于BHP定量的标准物质，相关浓度以任意单位表示（峰面积/微克沉积物）。
