Surface sediments (n=39) from the western Fram Strait and across the Yermak Plateau (Arctic Ocean) were investigated by molecular and isotopic organic geochemical methods to determine the composition, distribution and origin of extractable aliphatic lipids (n-alkanes, n-alkanols, fatty acids).

Surface sediments (n=39) from the western Fram Strait and across the Yermak Plateau (Arctic Ocean) were investigated by molecular and isotopic organic geochemical methods to determine the composition, distribution and origin of extractable aliphatic lipids (n-alkanes, n-alkanols, fatty acids). Bulk geochemical parameters (TOC-content, d13Corg) were also determined, including additional samples nearby. Enhanced organic carbon contents of up to 1.6% along the western slope of the Yermak Plateau and north off Spitsbergen, corroborated by an average d13Corg value of -22.3 per mil, indicated most of the organic material to be of a marine origin, despite ice-cover. The extractable aliphatic lipids contributed up to 1% of the sedimentary organic carbon and were dominated by fatty acids (0.7-9.1 mg/g TOC), whereas n-alkanes and n-alkanols contributed only minor amounts (0.1-0.4 mg/g TOC).
