    • Stable isotope database - Transport and fate of nutrient and pathogen loadings into nearshore Puget Sound: consequences for shellfish growing areas

    Metadata Updated: May 24, 2025

    This project seeks to develop and apply an assessment of shellfish growing area (SGA) vulnerability to closures caused by watershed- and marine-derived pathogens. Using empirical data and quantitative models, we will examine the impacts of alternative watershed management strategies, nearshore protection, and climate on the vulnerability of three SGA.

    Outputs include the following:

    1) Maps of the spatial distribution of terrestrial and marine-derived sources of nutrients and pathogens.

    2) Validated model estimates of transport of nutrients and pathogens to SGA under future climate and restoration strategies.

    3) Assessments of the fate of nutrients and pathogens in terms of changes in ecosystem service values provided by SGA--filtration, food web support, and socio-economic impacts due to harvest closures. Outcomes include improvements in the ability of shellfish growers and managers to classify vulnerability of SGA according to risk of future closures, and to prioritize strategies for improving delivery of shellfish-related ecosystem services and values. Stable isotopes of Carbon and Nitrogen for Pacific oysters and potential diet sources from marine and freshwater sources in the Samish, Hamma Hamma and Dosewallips growing areas. This dataset also includes water quality parameters from CTD casts at high tide in the oyster beds.
