Here we present detailed organic carbon (OC) records from the entire ca. 200 m thick Paleogene OC-rich section of the ACEX drill sites. These records indicate euxinic „Black Sea-type“ conditions favorable for the preservation of labile aquatic (marine algae-type) OC occur throughout the upper part of the early Eocene and the middle Eocene, explained by salinity stratification due to freshwater discharge. The superimposed short-term („Milankovitch-type“) variability in amount and composition of OC is related to changes in primary production and terrigenous input. Prominent early Eocene events of algae-type OC preservation coincide with global d13C events such as the PETM and Elmo events. The Elmo d13C Event has been identified in the Arctic Ocean for the first time.","descriptionType":"Abstract"},{"description":"Supplement to: Stein, Ruediger; Boucsein, Bettina; Meyer, Hanno (2006): Anoxia and high primary production in the Paleogene central Arctic Ocean: first detailed records from Lomonosov Ridge.
