Projects

Mechanisms Controlling Hypoxia – Integrated Causal...

We’re examining the complex physical and biogeochemical relations that control and maintain the low-oxygen dead zone in the northern Gulf of Mexico (nGOM). We are combining field data from moored ...

Mercury Hot Spots and Bioaccumulation in Fish

We identify which species of fish and which harvest locations expose consumers the most to potentially toxic mercury. With this information, we seek to develop the ability to predict which ...

Metabolism and Physiology of Red Tide Toxins in Tu...

Endangered sea turtles experience severe mortality during Florida red tides. This project uses non-endangered freshwater turtles as a model animal to determine the effects of Florida red tide on endangered ...

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 ...

Nanomaterials in the Marine Environment: The Use o...

In our study of the movement and accumulation of gold and silver nanomaterials in simulated salt-marsh enclosures, we found that the particles moved from the water column and were taken ...

National Mussel Watch Program: 2022 Assessment of ...

Contaminants of emerging concern (CECs) — such as mercury, chlorinated paraffins, and per-and polyfluoroalkyl (PFAS) substances — are a threat to human and ecosystem health in the Great Lakes region ...

New Tools to Aid in Managing Ciguatera Poisoning R...

Ciguatera fish poisoning is the most frequently reported non-bacterial illness associated with eating fish in the United States and the U. S. territorial islands. Ciguatera significantly impacts commercial and recreational ...

Nutrient Dynamics and Changes to Benthic Communiti...

Eutrophication is the over-abundance of nutrients in a body of water that results in harmful algal blooms, fish kills, and in some cases ecosystem collapse. In coral reef ecosystems, excess ...

New Report Characterizes Offshore, Soft-bottom Hab...

NCCOS scientists completed a study of the soft-bottom habitats in offshore areas of the Florida Keys National Marine Sanctuary (FKNMS). While FKNMS is known for its coral reefs and extensive ...

Study Finds Pharmaceuticals, Other Contaminants in...

NOAA scientists recently completed regional assessments of contaminants of emerging concern (CEC) for Chesapeake Bay, Maryland, and Charleston Harbor, South Carolina. Conducted as part of NOAA’s Mussel Watch Program, these ...

NCCOS, Partners Publish Environmental Assessment o...

NCCOS and its partners have published an environmental assessment of Nushagak and Kvichak Bays, two of the most important salmon fishing grounds in Bristol Bay, Alaska. Bristol Bay supports the ...

New Research from NCCOS Could Improve Survival of ...

The threatened Florida manatee, Trichechus manatus latirostris, inhabits coastal environments where blooms of the toxic red tide dinoflagellate, Karenia brevis, frequently occur. K. brevis produces a suite of neurotoxins, called ...

Scientists Assess Contaminants, Fish Populations i...

Study Examines Relationship Between Air and Water ...

Long-term atmospheric deposition and surface water quality nutrient monitoring locations summarized at a HUC-8 level. Depicted are watersheds with: no long-term monitoring sites (grey); only water quality (light blue); only ...

$11.75M Awarded for Ocean Acidification, Coral Eco...

NOAA’s National Centers for Coastal Ocean Science (NCCOS) are pleased to announce a total of $4.37 million in funding for 16 new research awards in Fiscal Year 2018, with an ...

Summer 'Dead Zone' Smaller than Average in Gulf of...

NOAA-supported scientists, led by partners at the Louisiana Universities Marine Consortium (LUMCON) and Louisiana State University, have determined that this year’s Gulf of Mexico “dead zone”—an area of low oxygen ...

Determining Ciguatera Risk in Invasive Lionfish

The lionfish is invasive to the Atlantic, Gulf of Mexico, and Caribbean. Credit: NOAA Scientists are investigating the prevalence of ciguatera toxins in invasive lionfish in response to interest in ...

Data & Publications

Great Lakes Mussel Watch: Assessment of Contaminants of Emerging Concern

The current report summarizes Great Lakes mussel tissue contaminants of emerging concern (CEC) data obtained between 2013-2015. The study design informs MWP management, stakeholders and general public about the frequency of occurrence, and the magnitude of CECs in mussels. We ...

Gulf of Mexico Hypoxia: Exploring Increasing Sensitivity to Nitrogen Loads

Hypoxia is a critical issue in the Gulf of Mexico that has challenged management efforts in recent years by an increase in hypoxia sensitivity to nitrogen loads. Several mechanisms have been proposed to explain the recent increase in sensitivity. Two ...

Historical Nitrogen and Phosphorus Loadings to the Northern Gulf of Mexico

The purpose of this analysis is to examine the historical fluxes of N and P to the northern Gulf of Mexico and discuss the implications that this may have for primary productivity, hypoxia and management strategies ...

Historical trends of hypoxia in Changjiang River estuary: Applications of chemical biomarkers and microfossils

Over the past two decades China has become the largest global consumer of fertilizers, which has enhanced river nutrient fluxes and caused eutrophication and hypoxia in the Yangtze (Changjiang) large river delta-front estuary (LDE). In this study, we utilized plant ...

Human Use Pharmaceuticals in the Estuarine Environments: A Survey in the Chesapeake and Biscayne Bays

The goal of this pilot project was to assess the presence of a number of commonly prescribed human use pharmaceuticals in three coastal areas of the U.S. Water samples were collected in conjunction with three NOAA monitoring/research projects to assess ...

Hydrographic and chemical water parameters collected by CTD and other instruments from the Pelican and the Tommy Munro in coastal waters of Louisiana from 1994-07-24 to 1997-07-29 (NCEI Accession 0164298)

Hydrographic and chemical data were collected for a week in late July between 1994-1997 in order to survey the coastal hypoxia on Louisiana continental shelf. Nutrient, pigment, suspended sediment and station information data were also acquired. Data files provided in ...

Interannual Variation in Stratification over the Texas–Louisiana Continental Shelf and Effects on Seasonal Hypoxia

A numerical dye is used to track freshwater released in May and June from the Mississippi and Atchafalaya rivers using a hydrodynamic model. These months are chosen because discharge and nutrient load in May and June is significantly correlated with ...

Landscape-Level Variation in Disease Susceptibility Related to Shallow-Water Hypoxia

Diel-cycling hypoxia is widespread in shallow portions of estuaries and lagoons, especially in systems with high nutrient loads resulting from human activities. Far less is known about the effects of this form of hypoxia than deeper-water seasonal or persistent low ...

Linking Coasts and Seas to Address Ocean Deoxygenation

Accelerated oxygen loss in both coastal and open oceans is generating complex biological responses; future understanding and management will require holistic integration of currently fragmented oxygen observation and research programmes ...

Linking molecular microbial ecology to geochemistry in a coastal hypoxic zone

Multiple environmental mechanisms have been proposed to control bottom water hypoxia (<2 mg O2 L?1) in the northern Gulf of Mexico Louisiana shelf. Near-bottom hypoxia has been attributed to a direct consumption of oxygen through benthic microbial respiration and a ...
