Geochemical data (NERC grant NE/K005251/1)
Organic and inorganic data extracted from core material spanning over a large area of the Baltic basin (Kostovo-13, Grotlingbo-1, File Haidar-1, Boda Hamn-1, Hamnudden-1, Finngrundet-1, Barstad-2 and Bernstorp-1). Organic data include concentrations in pristane, phytane, phenanthrene, methylphenanthrene and arylisoprenoids. Inorganic data include iron speciation data, concentrations in Fe, Al, P, U, Mo, V, total organic C, and C isotope ratios.

The Fe speciation method (Poulton and Canfield, 2005; Canfield et al., 1986) was used to extract sequentially highly reactive Fe phases. Bulk sediments were digested by a HNO3-HF-HClO4-H3BO3-HCl dissolution. Al and P, V, Mo and U concentrations in total digestions were determined by ICP-MS. Fe concentrations were determined by AAS. TOC was determined by the difference between total carbon (TC) before and after inorganic carbon removal (two 25% (vol/vol) HCl washes for 24 hours). Samples were analyzed on a carbon analyzer. Carbon isotope ratios of decarbonated samples were analyzed on a Thermo DELTA V mass spectrometer. Biomarker extractions were performed following the methodology described in detail by Brocks et al., 2008 and Jarrett et al., 2013.
