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.

该项目的目的是量化和确定北冰洋中部罗蒙诺索夫海岭IODP 302孔沉积物中特定有机物及其在新生代的变化。将使用有机岩相分析（显微组分分析、镜质体反射率）来重建控制有机物沉积背景的古环境和古气候条件。计划对晚白垩世/新生代沉积物进行的首次研究将使人们能够估算北冰洋中部从温暖（无冰）北冰洋向寒冷（有冰）北冰洋演变期间的有机碳通量。此外，获得解释富有机质沉积物（晚白垩世/古近纪）形成的模式也将是一个重点。
