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 work by our group in the Columbia River plume region and Salish Sea. These three papers document the physics, plankton biology, and oxygen chemistry in the model:

The biogeochemistry in the Cascadia model is extremely simple but has been tuned and validated with a wealth of local field observations:

which discusses in detail the use of microzooplankton dilution experiments to design the “Z” component of the model.
