Chlorine concentration of sediment core MD01-2416

Chlorin concentrations were calculated from CPE (chloroplastic pigment equivalents) values measured with a Turner-Flourometer TD-700, applying standard procedures of IFM-GEOMAR, Kiel. Pigments were released with acetone and a cell-mill from 100 mg of freeze-dried and crushed sediment and acidified with HCl to change chlorophyll-a into phaeopigments. A Sigma-Aldrich 25730-chlorophyll-a solution was used to produce a standard for CPE-measurements. Chlorin concentrations are given in ng/g.
