Abstract

Summary

The Study addresses the subject of ancient carbon utilization in sediments of Hornsund Fjord, Svalbard. Using a combined approach of biomarker analysis, lipidology, and compound specific radiocarbon dating. We were able to show that the local sedimentary microbes utilize "presumably recalcitrant" petrogenic organic matter for their biosynthesis to a certain extend. Indicating its degradation in the subsurface and hence displaying a not yet accounted source of fissile carbon entering today's carbon cycle.
