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

flowWeaver: Visualizing the circulation of the Pacific Northwest coast

flowWeaver is an interactive tool for exploring transport and connectivity patterns in high-resolution ocean models such as ROMS. The initial application (version 0.4.3) contains two weeks of Salish Sea and Pacific Northwest coastal circulation during summer 2005. The underlying ocean model is MoSSea (Modeling the Salish Sea). Pablo Otero has adapted flowWeaver for an operational … 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

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
