Summary
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.

Purpose
Sediment geochemistry was explored to increase understanding about sediment and contaminant accumulation and provenance in Bellingham Bay over historical time scales. Improved understanding about sediment sources and dispersal patterns in the past few hundred years can inform current understanding and future projections about sediment and sediment-bound contaminant inputs, transport, fate, and potential effects on nearshore ecosystems. The U.S. Geological Survey (USGS) Coastal Habitats in Puget Sound Project (CHIPS), under which the current study was conducted, pairs geochemical data, oceanographic measurements, and hydrodynamic models to inform management decisions aimed at reducing negative effects of land-based materials on valued nearshore habitats and species and to support ecosystem recovery planning.
