Certain species of the phytoplankton Pseudo-nitzschia (PN) produce a potent neurotoxin, domoic acid (DA), that bioaccumulates in shellfish, and can cause severe illness and death in humans. Past outbreaks have caused fisheries closures and millions of dollars of losses to crab and clam harvesters, and contributed to the death of many species of marine mammals. … Read more
Climate change pushes on coastal and estuarine regions by a lot of pathways simultaneously, and it is surprisingly hard to untangle and prioritise these. As just one example from the US Pacific Northwest: should we expect future water temperatures to go up or down? Up makes sense, because of atmospheric warming. Down also makes sense, … Read more
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
The Eastern Bering Sea hosts extremely rich pelagic and benthic fisheries, and also experiences strong interannual variation in both fisheries recruitment and the underlying physics and plankton biology. This paper…
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
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 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
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. This paper… Banas NS (2011) … Read more
