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

Northwest Coastal Stories: Turbulence and Uncertainty in Science and in Culture

Program on the Comparative History of Ideas (CHID), Oceanography, and Honors Program, 2004–2013 Course announcement: This course will follow Jonathan Raban’s remarkable travelogue Passage to Juneau on a tour through the human and natural history of the Pacific Northwest coastal waters. We’ll discuss chaos theory and the circulation of Puget Sound; coastal ecology and climate … Read more

FISH 330: Climate Impacts on Marine Ecosystems (2013)

Course announcement: This course links the physics of climate to marine ecosystem processes, exploring both observed climate impacts from the past and projected impacts of human-caused climate change in the future. Case studies include a spectrum of organisms from plankton to whales, in polar, sub-arctic, temperate, tropical, and upwelling ecosystems. We will also discuss the … 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. For more information, see Banas NS, Lessard E, Kudela R, MacCready P, Peterson T, … Read more
