basis: Sachs and Sachse 2008, GCA , 72:793-806; "dD values of lipids...were closely correlated with salinity, owing to a decrease in D/H fractionation between lipids and source water as salinity increases. TLE dD values can therefore be used as a salinity indicator in hypersaline evnrionments such as those at Christmas Island".
