A total of 4 geological stations were chosen to obtain Jumbo piston core sediments based on previously collected data for geophysical records, providing age control, and investigating paleoceanographic environments. Retrieved cores were described, photographed, and logged on the Geotek Multi-Sensor Core Logger. Detailed analyses such as stable isotopes of planktonic and benthic foraminifers, organic geochemistr0y, biogenic opal contents, microfossils and biomarkers will be performed after this expedition. The overall objective of coring using the Jumbo Piston Corer during cruise ARA06C was to obtain longer records of sediments to constrain, and thus better understand, the timing and chronology of marine glaciations along the East-Siberian and Chukchi continental margins.
