Harmful Algal Bloom Event Response: Helping New Yo...

Emergency funds from NCCOS allowed New York to monitor algal toxins during a bloom event that coincided with a state spending freeze. Shellfish consumers and the reputation of one of ...

Harmful Algal Blooms Event Response: Responding to...

We helped Alaska state regulators, the shellfish industry, and community leaders initiate routine, rapid screening of noncommercial shellfish in southeast Alaska for paralytic shellfish poisoning (PSP) toxins. We also worked ...

Harmful Algal Blooms, Acidification and Climate Ch...

This project investigates the interactive effects of acidification, warming, and nutrients on three economically important harmful algal bloom (HAB) species in the Salish Sea. Spanning the western US-Canada border, the ...

Histological Techniques for Marine Bivalve Mollusk...

To best manage marine resources such as bivalve mollusks (i.e., clams, oysters) and crustaceans (i.e., crabs), scientists must have access to the tools needed to study the health of these ...

How will Climate Change Affect Harmful Algal Speci...

We are supporting research that will determine how future increases in temperature and ocean acidity will affect harmful algal bloom species (HABs) and their grazers. Light micrograph of Karlodinium veneficum ...

Historical Data Used to Analyze Red Tide Bloom Dyn...

Map of the study area. Nearly all annual blooms of the red tide-forming, toxic dinoflagellate Karenia brevis (K. brevis) pose a serious threat to coastal Southwest Florida. New research developed ...

New Study Unveils the Unique Seasonality in the De...

Interannual variations of winter and summer temperature in the Jordan Basin (location as shown in upper panel) at 150-m water depth. The vertical bars represent one standard deviation over the ...

Seasonal Differences in Gambierdiscus Abundance, T...

An NCCOS-sponsored study provides the most comprehensive and quantitative assessment to date of the in situ toxicity of Gambierdiscus marine dinoflagellates in the Caribbean. Study findings have implications for the ...

NCCOS Partners with CERF ‘Rising Tides’- Contribut...

NCCOS sponsored and participated in the 2021 Coastal and Estuarine Research Federation (CERF) 26th Biennial Conference, which was held virtually on November 1-4 and November 8-11, 2021. NCCOS scientists and ...

Data & Publications

Macro- to Fine-Scale Spatial and Temporal Distributions and Dynamics of Phytoplankton and Their Environmental Driving Forces in a Small Montane Lake in Southern California, USA

A wireless network of buoys, two autonomous robotic boats, and an autonomous tethered vertical profiling system were used to characterize phytoplankton dynamics and spatiotemporal changes in chemical and physical forcing factors in a small montane lake (Lake Fulmor, Idyllwild, California) ...

Mesozooplankton and Microzooplankton Grazing During Cyanobacterial Blooms in the Western Basin of Lake Erie

Lake Erie is the most socioeconomically important and productive of the Laurentian (North American) Great Lakes. Since the mid-1990s cyanobacterial blooms dominated primarily by Microcystis have emerged to become annual, late summer events in the western basin of Lake Erie ...

Mitigating the Expansion of Harmful Algal Blooms Across the Freshwater-to-Marine Continuum

Anthropogenic nutrient overenrichment, coupled with rising temperatures, and an increasing frequency of extreme hydrologic events (storms and droughts) are accelerating eutrophication and promoting the expansion of harmful algal blooms (HABs) across the freshwater-to-marine continuum. All HABs—with a focus here on ...

Model initialization in a tidally energetic regime: A dynamically adjusted objective analysis

A simple improvement to objective analysis of hydrographic data is proposed to eliminate spatial aliasing effects in tidally energetic regions. The proposed method consists of the evaluation of anomalies from observations with respect to circulation model fields. The procedure is ...

Model Simulations of the Bay of Fundy Gyre: 2. Hindcasts for 2005-2007 Reveal Interannual Variability in Retentiveness

A persistent gyre at the mouth of the Bay of Fundy results from a combination of tidal rectification and buoyancy forcing. Here we assess recent interannual variability in the strength of the gyre using data assimilative model simulations. Realistic hindcast ...

Models of harmful algal blooms: Conceptual, empirical, and numerical approaches

In June 2009, a workshop was convened under the auspices of the Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) program to develop strategies for using observations and models to address the science questions articulated in the Open Science ...

Models: Tools for synthesis in international oceanographic research programs

Through its promotion of coordinated international research programs, the Intergovernmental Oceanographic Commission (IOC) has facilitated major progress on some of the most challenging problems in oceanography. Issues of global significance—such as general ocean circulation, the carbon cycle, the structure and ...

Molecular Response of the Bloom-Forming Cyanobacterium, Microcystis aeruginosa, to Phosphorus Limitation

Cyanobacteria blooms caused by species such as Microcystis have become commonplace in many freshwater ecosystems. Although phosphorus (P) typically limits the growth of freshwater phytoplankton populations, little is known regarding the molecular response of Microcystis to variation in P concentrations ...

Monitoring Approaches for Early Warning of Domoic Acid Events in Washington State

On the U.S. west coast, blooms of the potentially toxic diatom Pseudo-nitzschia can cause amnesic shellfish poisoning (ASP), resulting in economic impacts to coastal economies and public health concerns. The transfer of toxin, via filter feeding of Pseudo-nitzschia or ingestion ...

Monitoring Oregon Coastal Harmful Algae: Observations and Implications of a Harmful Algal Bloom-Monitoring Project

The accumulation of domoic acid (DA) and saxitoxins (STX), phycotoxins produced by some species of Pseudo-nitzschia and Alexandrium, respectively, in coastal food webs are a focus of research on the West Coast of the United States due to the deleterious ...
