Calculate seawater d18O

Description

Calculate the oxygen isotope composition (d18O) of seawater from its salinity.

Usage

d18OwFromSalinity(Salinity)

Arguments

Salinity

salinity in grams per litre or parts per thousand.

Details

This is an implementation of the equation from Duplessy et al. (1991) based on the salinity for water samples collected in the upper 250 m of the Atlantic Ocean during the GEOSECS expedition, as reported in Anand et al. 2003.

Value

The oxygen isotope composition of seawater (d18Ow) as permille deviation from the SMOW scale.
