Age and long chain diol index from four sediment cores from the Arabian Sea

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 calibrated ages (expressed as cal kyr BP), long-chain diol long-chain diol index (LDI) and calculated sea surface temperatures. The data covers the last 25 kyr BP for two sediment cores and 35 kyr for the other two.

本文呈现了采自阿拉伯海西部与北部海域的四份不同海洋沉积记录的分析结果。这些记录于不同考察航次中采自不同区域：采自阿拉伯海西部阿曼-索马里上升流区的岩芯包括1986年采集的SO42-74KL（卡斯坦岩芯（Kasten core））与1993年采集的NIOP905（活塞岩芯（piston core））；采自阿拉伯海北部的岩芯则包括1998年采集的SO130-289KL（卡斯坦岩芯（Kasten core））与2009年采集的PASOM3（重力岩芯（gravity core））。本数据集包含校准年龄（以cal kyr BP表示）、长链二醇（long-chain diol）与长链二醇指数（LDI），以及反演计算得到的海表温度。其中两份岩芯的记录覆盖了距今25千年（cal kyr BP）以来的沉积序列，另外两份岩芯的记录覆盖时长则为距今35千年以来。
