Geochemistry of surface sediment and sediment cores in Bellingham Bay, Whatcom County, Washington, in February 2020

Geochemical data are reported for surface sediments and long sediment cores from Bellingham Bay, Whatcom County, Washington, collected in early February 2020 after flood conditions on the Nooksack River. Data include total organic carbon content (TOC), carbonate content (CaCO3), ratios of stable carbon 13/12 isotopes (d13C), ratios of total carbon to total nitrogen (C:N), short-lived cosmogenic radionuclide activities (Beryllium-7, Cesium-137, and excess Lead-210), and elemental chemistry.
