(Table 1) Sample information and stable hydrogen isotope composition of long-chain n-alkanes and weighted mean average stable hydrogen isotope composition

WMA: Weighted mean average stable hydrogen isotope composition (WMA).Standard deviation: 1 Sigma.a: Analysed sediment interval in cm below sea floor.b: Number of replicate n-alkane hydrogen isotope analyses.c: Boldface values refer to the two most abundant homologues.d: Calculated as weighted mean average based on alkane abundances (Vogts et al., 2012).
