Project description:
How the Arctic Carbon Cycle will change in a warming scenario holds the attention of the entire international community. Sea ice loss, permafrost thaw and ocean acidification are some examples of the expected perturbations. To support the community working on the Arctic Carbon complexity, we initiated the open CASCADE (Circum-Arctic Sediment CArbon DatabasE) digital infrastructure which enables pan-Arctic biogeochemical analyses, supports ecology studies and facilitates a wide array of models. CASCADE is the largest repository of organic geochemistry data of Arctic sediments. CASCADE benefits from several Arctic expeditions and includes bulk and biomarker organic geochemistry data of surface sediments and, to minor extent, sediment cores collected over the course of the last decades. CASCADE contains more than 4000 oceanographic stations of organic carbon (OC) concentrations, 2300 stations with total nitrogen (TN) concentrations, 1500 stations with stable carbon isotopes (?¹³C), about 270 stations with radiocarbon data (?¹4C) and also records with quantified terrigenous organic biomarkers. Now with this project, we promote the next phase of the CASCADE by reinforcing its pan-Arctic dimension and reducing the current gaps, including the Svalbard region.
