Projects

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 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 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, ...

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 ...

National Coral Reef Monitoring Program Implementat...

The National Coral Reef Monitoring Program (NCRMP) is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its ...

National Estuarine Eutrophication Assessment: Upda...

Eutrophication is the overabundance of nutrients in a body of water that results in harmful algal blooms, fish kills, and in some cases ecosystem collapse. We used the Assessment of ...

National Inventory of Deep-sea Corals and Sponges:...

We are working in support of NOAA’s Deep Sea Coral Research and Technology Program to locate, map, and characterize deep-sea coral and sponge ecosystems throughout U.S. and international waters. Information ...

Seafloor Mapping Mission Supports Better Character...

A goliath grouper over four feet in length inspects the ROV while dozens of other large grouper and massive schools of small fish swarm a steep ledge in Tortugas South ...

NCCOS Spatial Science Will Inform National Aquacul...

A presidential Executive Order signed in May 2020, Promoting American Seafood Competitiveness and Economic Growth, establishes NOAA as the lead agency on aquaculture in federal waters, and calls for establishment ...

Effects of Sea Level Rise Program Awards $2.2 Mill...

NOAA’s National Centers for Coastal Ocean Science (NCCOS) is allocating over $2.2M in Fiscal Year 2020 to fund coastal resilience research across the nation. Approximately $589K will cover the first ...

Smaller than Average Summer ‘Dead Zone’ Measured ...

NCCOS-supported scientists have determined that this year’s Gulf of Mexico “dead zone”—an area of low oxygen that can kill fish and marine life—is approximately 2,116 square miles, equivalent to 1.4 ...

NCCOS Vibrio Predictive Models (Story Map)

ESRI Story Map on Vibrio Predictive Models. Credit G. Messick, NOAA A story map has been created to describe the different Vibrio Predictive Models produced by NCCOS. These predictive models ...

NOAA Forecasts Larger than Average ‘Dead Zone’ for...

NCCOS scientists are forecasting this summer’s Gulf of Mexico hypoxic zone or “dead zone”—an area of low to no oxygen that can kill fish and other marine life— to be ...

Scientists Document Effect of Crude Oil on a Pacif...

NOAA, BOEM Develop New Tool to Reduce Dredging Imp...

As part of a recently completed two-year study funded by the Bureau of Ocean Energy Management (BOEM), NOAA’s National Centers for Coastal Ocean Science (NCCOS), NOAA's Office for Coastal Management ...

NCCOS, GCOOS Award $556K for New Studies to Uncove...

Across the U.S., the seafood, restaurant and tourism industries are estimated to suffer millions of dollars in economic losses from harmful algal blooms — losses played out in communities from ...

Data & Publications

Eutrophication-induced acidification of coastal waters in the northern Gulf of Mexico: Insights into origin and processes from a coupled physicalbiogeochemical model

Nutrient inputs from the Mississippi/Atchafalaya River system into the northern Gulf of Mexico promote high phytoplankton production and lead to high respiration rates. Respiration coupled with water column stratification results in seasonal summer hypoxia in bottom waters on the shelf ...

Evidence of climate-driven ecosystem reorganization in the Gulf of Mexico

The Gulf of Mexico is one of the most ecologically and economically valuable marine ecosystems in the world and is affected by a variety of natural and anthropogenic phenomena including climate, hurricanes, coastal development, agricultural runoff, oil spills, and fishing ...

Expedition Report: 2017 Southeast Deep Coral Initiative (SEDCI) expedition aboard NOAA Ship Nancy Foster (NF-17-08: August 12-31, 2017)

On August 12-31, 2017 the National Centers for Coastal Ocean Science (NCCOS) led a research expedition aboard NOAA Ship Nancy Foster supported by NOAA’s Deep Sea Coral Research and Technology Program (DSCRTP) through the Southeast Deep Coral Initiative (SEDCI). The ...

Exploratory Treatments for Stony Coral Tissue Loss Disease: Pillar Coral (Dendrogyra cylindrus)

Pillar coral (Dendrogyra cylindrus) is a rare Caribbean coral with only one species in its genus. Because of population declines, the species was listed as threatened under the U.S. Endangered Species Act in 2014 (Federal Register 2014). By 2020, the ...

Exploring estuarine eutrophication sensitivity to nutrient loading

The sensitivity of surface chlorophyll (Chl) and bottom water dissolved oxygen (DO) to total nitrogen (TN) load was investigated using a Bayesian?based process model fit to data from a range of estuaries. The model was used to test if the ...

Extensive reproductive disruption, ovarian masculinization and aromatase suppression in Atlantic croaker in the northern Gulf of Mexico hypoxic zone

The long-term impacts on marine ecosystems of the recent dramatic worldwide increase in the incidence of coastal hypoxia are unknown. Here, we show widespread reproductive disruption in Atlantic croakers collected from hypoxic sites approximately 120 km apart in the extensive ...

Fish assemblages associated with red grouper pits at Pulley Ridge, a mesophotic reef in the Gulf of Mexico

Red grouper (Epinephelus morio) modify their habitat by excavating sediment to expose rocky pits, providing structurally complex habitat for many fish species. Surveys conducted with remotely operated vehicles from 2012 through 2015 were used to characterize fish assemblages associated with ...

Fitness consequences of habitat variability, trophic position, and energy allocation across the depth distribution of a coral-reef fish

Environmental clines such as latitude and depth that limit species’ distributions may be associated with gradients in habitat suitability that can affect the fitness of an organism. With the global loss of shallow-water photosynthetic coral reefs, mesophotic coral ecosystems (~30–150 ...

Genetic and biophysical modelling evidence of generational connectivity in the intensively exploited, Western North Atlantic red grouper (Epinephelus morio)

Understanding the connectivity of reef organisms is important to assist in the conservation of biological diversity and to facilitate sustainable fisheries in these ecosystems. Common methods to assess reef connectivity include both population genetics and biophysical modelling. Individually, these techniques ...

Genetic connectivity dynamics of the giant barrel sponge, Xestospongia muta, across the Florida reef tract and Gulf of Mexico

Resolving the genetic connectivity of coral reef taxa is necessary to understand the community dynamics of these increasingly threatened ecosystems. Herein, we assess the fine scale genetic connectivity of six populations of the Atlantic giant barrel sponge, Xestospongia muta (Schmidt, ...
