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.
