Modeling Cascadia

The Cascadia model from the Univ of Washington Coastal Modeling Group is a realistic 3D model, implemented in ROMS, of the North American Pacific Northwest coast from mid-Oregon to mid-Vancouver Island, including the inland waters of the Salish Sea. It was developed as part of the NSF/NOAA PNWTOX (Pacific Northwest Toxins) project, based on previous … Read more

Connectivity among rivers and subbasins of Puget Sound

Compared with most large, temperate estuaries, the biogeochemistry of Puget Sound is highly marine dominated: 70% of dissolved nutrients come from the Pacific. Nevertheless, there’s significant policy and management interest in understanding watershed contributions of environmental stressors, e.g. nutrient loading in relation to hypoxia, and pathogen and pollutant impacts on commercial, recreational, and tribal shellfish … Read more

Adding fine-scale trophic complexity to a plankton model

Natural plankton communities are far more diverse than even a very complicated numerical model can account for. The ASTroCAT model (Allometric/Stochastic Trophic Complexity Analysis Tool) is an experiment in systematically resolving the complexity in phytoplankton–microzooplankton trophic interactions, and exploring the effects of this complexity on ecosystem structure, function, and predictability. The model runs interactively in … Read more

Biophysical modeling of the Columbia River plume (2009)

The model As part of the NSF RISE (River Influences on Shelf Ecosystems) program, my collaborators and I coupled a four-box ecosystem model to a high-resolution hindcast of the Washington-Oregon coast, to examine Columbia River plume effects on coastal biological production.
