The project aims at the quantification and identification of the particular organic matter and its variation through Cenozoic times in sediments from IODP hole 302 from the Lomonosov Ridge, Central Arctic Ocean. Organic-petrographical analyses (maceral analysis, vitrinite reflectance) will be used for the reconstruction of the paleoenvironmental and paleoclimatic conditions, which controls the depositional setting of the organic matter. The planned studies on late Cretaceous/Cenozoic sediments for the first time will allow the organic-carbon-flux estimation in the Central Arctic Ocean during its evolution from a warm (ice-free) to a cold (ice-covered) Arctic Ocean. Furthermore, the attainment of a model explaining the formation of organic-rich sediments (late Cretaceous/ Paleogene) will be also a focus.
