Projects

Mitigating Microcystis in the Chesapeake Bay

Chitosan, a natural compound, is added to concentrations of local sediments and commercial clays to control harmful algal blooms. We are studying the impacts of this mitigation technique on natural ...

Modeling Approach to Predicting Nitrogen Removal b...

Burning fossil fuel, applying fertilizers, and other activities have resulted in nutrient-loaded runoff that can cause the overgrowth of algae and seaweeds in coastal waters such as Greenwich Harbor. This ...

Modeling Factors that Contribute to Harmful Algal ...

Harmful algal blooms that disrupt and degrade coastal aquatic ecosystems are occurring with greater frequency. We developed a model that shows these events are not only the result of nutrient ...

Modeling Favorable Habitat for Alexandrium catenel...

In Puget Sound, the toxic alga Alexandrium catenella threatens people who eat shellfish contaminated with the algal toxin. Previous studies identify “seedbeds” of Alexandrium resting stages (cysts) on the bottom ...

Modeling Hypoxia and Ecological Responses to Clima...

We are developing modeling tools that can be used to predict ecological responses to climate and nutrient input management in coastal systems. This project is part of NOAA’s Coastal Hypoxia ...

Modeling Impacts of Hypoxia in the Northern Gulf o...

We are determining the effects of hypoxia (low dissolved oxygen) on reproduction of fish (Atlantic croaker) throughout the northern Gulf of Mexico to accurately model population outcomes and to assess ...

Modeling Ocean Acidification in the Coastal Zone

Adding carbon dioxide (CO2) to seawater raises the acidity of seawater, which can adversely affect marine life and fisheries. Coastal waters receive both atmospheric CO2 and CO2 from water pollution, ...

Monitoring and Event Response for Harmful Algal Bl...

Monitoring and Event Response for Harmful Algal Blooms in the Lower Great Lakes (MERHAB-LGL) was the first regional, multi-institution project to examine toxic cyanobacteria in the lower Great Lakes and ...

Monitoring and Management of Lipophilic Shellfish ...

Lipid and fat soluble (lipophilic) algal toxins linked to diarrhetic shellfish poisoning and azaspiracid shellfish poisoning are emerging threats to recreational, subsistence, and commercial shellfisheries in the state of Washington ...

Multidisciplinary Approach to a Cross-Regional Pro...

Diarrhetic shellfish poisoning (DSP) has emerged as a significant and expanding seafood safety threat in coastal regions across the United States. The harmful algal species Dinophysis produces toxins known to ...

Temperature and Oxygen Tolerances of Marine Specie...

NCCOS-supported researchers found that marine organism geographic distributions are best predicted by measuring temperature and dissolved oxygen together. Temperature and oxygen are closely linked in the physiology of marine animals ...

Comparing Saginaw Bay and Western Lake Erie for Ha...

MODIS satellite image (undated) of Lake Huron/Saginaw Bay and the Western Lake Erie basin showing cyanobacterial blooms (greenish areas), Credit NASA. Scientists from NCCOS and the University of Maryland collaborated ...

NCCOS Assists Response to Quantify Toxin Accumulat...

NOAA’s National Centers for Coastal Ocean Science (NCCOS) provided a harmful algal bloom (HAB) Event Response award of $15,482 to the University of Florida, Florida’s Clinic for the Rehabilitation of ...

U.S. Socio-economic Effects of Harmful Algal Bloom...

NCCOS Competitive Research Program (CRP) and the U.S. National Office for Harmful Algal Blooms at the Woods Hole Oceanographic Institution (WHOI) released proceedings from a 2020 workshop on the socio-economic ...

New Study Describes Transport of Toxic Freshwater ...

An NCCOS-sponsored study found that freshwater cyanobacteria, and their toxins, produced in a compartmentalized California estuary can accumulate and enter marine waters episodically, particularly during storms and significant tidal exchange ...

Fishing for Hypoxia

Hypoxia in Tropical Marine Ecosystems, the Underst...

A recent review article by NCCOS-supported researchers assessing the state of knowledge of hypoxia (low oxygen) in tropical ecosystems finds little information in comparison to what is known about hypoxia ...

Impacts of Hypoxia on Marine Life Neglected, Thoug...

Map shows coastal sites where anthropogenic nutrients have exacerbated or caused oxygen declines to <2 mg/L (red dots), as well as ocean oxygen-minimum zones at 300 meters of depth (blue ...

Virtual Workshop Empowers Arctic Tribal Communitie...

NCCOS scientists, in collaboration with Ocean and Earth Environmental Services, conducted a virtual workshop in January to introduce members of the Norton Sound Health Corporation (NSHC) to methods and techniques ...

Researchers Stop Tissue Loss Disease in Rescued Pi...

Scientists from NOAA’s National Centers for Coastal Ocean Science (NCCOS) have successfully treated and rehabilitated diseased pillar coral rescued from the Florida Reef Tract. First detected near Miami in 2014, ...

Data & Publications

Louisiana Hypoxia Surveys 2007: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2007 (NODC Accession 0060060)

Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2007 ...

Louisiana Hypoxia Surveys 2008: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2008 (NODC Accession 0069471)

Two sets of CTD data were taken during the 2008 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, secchi depth, and ...

Louisiana Hypoxia Surveys 2011: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2011 (NCEI Accession 0129417)

Two sets of CTD data were taken during the 2011 surveys of the Louisiana continental shelf. Hydrographic data were obtained with the LUMCON SeaBird 911+ CTD system and a YSI 6820. Nutrient, pigment, suspended sediment, surface salinity, secchi depth, and ...

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) ...

Macrobenthos and megabenthos responses to long-term, large-scale hypoxia on the Louisiana continental shelf

The macrobenthos and megabenthos responses to long-term, recurring hypoxia on the Louisiana continental shelf were compared at four locations with different historical (2000–2010) episodes of annual exposure to bottom-water hypoxia. Measurements of abundance, biomass, species diversity, and community composition of ...

Magnitude and Extent of Contaminated Sediment and Toxicity in Chesapeake Bay

This document contains analytical methods that detail the procedures for determining major and trace element concentrations in bivalve tissue and sediment samples collected as part of the National Status and Trends Program (NS&T) for the years 2000-2006. Previously published NOAA ...

Mapping bottom-contact fishing intensity in the Gulf of Mexico in relation to predicted suitable habitat for deep sea corals

NCCOS has recently completed predictive habitat suitability models for 21 species and groups of deep corals in the Gulf of Mexico, including framework-forming deep corals. These models are being used to advise the Gulf of Mexico FMC on possible deep ...

Measurement of Turbidity, Suspended Sediments and Nutrients in Three Rivers that Drain to the Achang Preserve from the Manell Watershed, Guam
