Sediment Core Data from 2023 SKQ202309T Training Cruise (Gulf of Alaska, Bering Sea)

This dataset provides total Pb-210 (Lead-210) activity values (and corresponding dry bulk density values and porosities) for three sediment cores collected during a 2023 Arctic Chief Scientist training cruise on R/V Sikuliaq. Cores were collected from the Gulf of Alaska and Alaskan Beaufort Sea in June 2023 for training purposes and because of curiosity about general sediment accumulation rates in these areas. Cores were subsampled at 1 centimeter (cm) intervals in the field and returned to Oregon State University (OSU) for post-processing. In addition to Pb-210 activities and related parameters, sediment grain-size distribution data are also provided for one core. Core 01MC was a gravity core and cores 04MC and 08MC were multicores.
