Coltrane (Copepod Life-history Traits and Adaptation to Novel Environments)

The Coltrane (Copepod Life history Traits and Adaptation to New Environments) model is a mathematical framework for layering multiple levels of mesozooplankton biology on top of oceanographic models. It resolves 1) individual life history (strategy traits controlling growth, development, and size, diagnosed from a broad review of lab studies); 2) population dynamics (the time-dependent energy … Read more

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

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
