Data & Publications

Responses of the coastal phytoplankton community to tropical cyclones revealed by high-frequency imaging flow cytometry

To investigate the response of a subtropical coastal phytoplankton community to tropical cyclones, we utilized high temporal resolution (hours) data from the Imaging FlowCytobot (IFCB) deployed in the Gulf of Mexico. In 2010, four tropical cyclones (two during June–July and ...

Seasonal and interannual oxygen variability on the Washington and Oregon continental shelves

The coastal waters of the northern portion of the California Current System experience a seasonal decline in oxygen concentrations and hypoxia over the summer upwelling season that results in negative impacts on habitat for many organisms. Using a regional model ...

Seasonal Cross-Shelf Flow Structure, Upwelling Relaxation, and the Alongshelf Pressure Gradient in the Northern California Current System

Moored observations are used to investigate the seasonal change in vertical structure of the cross-shelf circulation at a midshelf location in the northern California Current System. A streamwise–normal coordinate system is employed to eliminate meander- and eddy-induced biases in the ...

Seasonal dynamics of the toxic dinoflagellate Alexandrium catenella at Redondo Beach, California, examined by quantitative PCR

The presence of neurotoxic species within the genus Alexandrium along the U.S. coastline has raised concern of potential poisoning through the consumption of contaminated seafood. Paralytic shellfish toxins (PSTs) detected in shellfish provide evidence that these harmful events have increased ...

Skill assessment for coupled biological/physical models of marine systems

Simulation models coupling physics to biological processes in the ocean are central to many current programs. Ocean physical models have approached a high level of sophistication; the physical relationships are canonical, and modern computational technology for fluid mechanics has advanced ...

Skill Assessment for Coupled Biological/Physical Models of Marine Systems

Coupled biological/physical models of marine systems serve many purposes including the synthesis of information, hypothesis generation, and as a tool for numerical experimentation. However, marine system models are increasingly used for prediction to support high-stakes decision-making. In such applications it ...

Suppression of the 2010 Alexandrium fundyense bloom by changes in physical, biological, and chemical properties of the Gulf of Maine

For the period 2005–2009, the abundance of resting cysts in bottom sediments from the preceding autumn was a first-order predictor of the overall severity of spring–summer blooms of Alexandrium fundyense in the western Gulf of Maine and southern New England ...

The globally distributed genus Alexandrium: Multifaceted roles in marine ecosystems and impacts on human health

The dinoflagellate genus Alexandrium is one of the major harmful algal bloom (HAB) genera with respect to the diversity, magnitude and consequences of blooms. The ability of Alexandrium to colonize multiple habitats and to persist over large regions through time ...

The influence of anthropogenic nitrogen loading and meteorological conditions on the dynamics and toxicity of Alexandrium fundyense blooms in a New York (USA) estuary

The goal of this two-year study was to explore the role of nutrients and climatic conditions in promoting reoccurring Alexandrium fundyense blooms in the Northport-Huntington Bay complex, NY, USA. A bloom in 2007 was short and small (3 weeks, 103 ...

The role of a PSP-producing Alexandrium bloom in an unprecedented diamondback terrapin (Malaclemys terrapin) mortality event in Flanders Bay, New York, USA

Diamondback terrapins (Malaclemys terrapin) are a threatened or endangered species in much of their range along the U.S. Atlantic and Gulf coasts. Over an approximately three-week period from late April to mid-May 2015, hundreds of adult diamondback terrapins were found ...
