Historical and geospatial variations of translocated permafrost carbon in Circum-Arctic Shelf Sediments

My PhD project investigates historical and geospatial variability of permafrost carbon (PF-C) that was remobilized and transported to Arctic Ocean shelf sediments. I study the historical PF-C input using molecular (n-alkanoic acids, n-alkanes, CuO oxidation products) and isotopic (δ13C, δ2H, Δ14C) analysis of sediment cores and surface sediments. Understanding Arctic Ocean sediment carbon inventory and pathways is of relevance for the global carbon cycle, especially with respect to permafrost carbon – climate feedback processes.

Biogeochemistry

How human activities affect natural processes that drive the major biogeochemical cycles that ultimately govern the composition of the environment.
