The East Gotland Basin (Baltic Sea) as a candidate Global Boundary Stratotype Section and Point for the Anthropocene series

The short sediment core EMB201/7-4 retrieved from the East Gotland Basin, central Baltic Sea, is explored here as a candidate to host stratigraphical basis for Anthropocene series and its equivalent epoch, still be formalized in Geological Time Scale. has been accurately dated back 1840 CE using well-established event stratigraphy approach. A pronounced significant change occurs at 26.5 cm (dated 1956 ± 4 CE) range of geochemical markers including 239+240 Pu, 241 Am, fly-ash particles, DDT (organochlorine insecticide), total organic carbon, bulk carbon stable isotopes. This stratigraphic level, which corresponds both lithology colour related early anthropogenic-triggered eutrophication proposed Global boundary Stratotype Section Point series.
