Long chain diols from four Arabian Sea sediment cores, data from 4 different expeditions

Here, we present results from four different marine archives from the western and northern Arabian Sea. They were collected from different areas during different expeditions; SO42-74KL (in 1986; Kasten core) and NIOP905 (in 1993; piston core) from the western Arabian Sea, Oman - Somali upwelling zone; SO130-289KL (in 1998; Kasten core) and PASOM3 (in 2009; gravity core) from the northern Arabian Sea. This dataset presents core depths (in cm), corresponding calibrated ages expressed as cal kyr BP, long-chain diols fractional abundances, and related indices such as long-chain diol index (LDI) as Diol upwelling index (DI). The data covers the last 25 kyr BP.

本研究报道了阿拉伯海西部与北部海域四份海洋沉积档案的分析结果。这些档案通过多航次科考在不同区域采集获得：SO42-74KL（1986年采集，箱式岩心（Kasten core））与NIOP905（1993年采集，活塞岩心（piston core））采自阿拉伯海西部阿曼-索马里上升流区；SO130-289KL（1998年采集，箱式岩心（Kasten core））与PASOM3（2009年采集，重力岩心（gravity core））采自阿拉伯海北部海域。本数据集包含岩心深度（单位：厘米）、以校正千年距今（cal kyr BP）表示的对应校正年龄、长链二醇的相对丰度，以及相关指数——例如作为二醇上升流指数（DI）的长链二醇指数（LDI）。该数据集覆盖了距今25千年以来的沉积记录。
