Study Finds Pollution Low in American Samoa’s Faga...

American Samoa’s coral reefs are some of the most pristine reefs in the United States. They host more than a thousand species of marine life, including some of the oldest ...

NOAA Forecasts An Average ‘Dead Zone’ for Gulf of ...

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 ...

Cape Lookout National Seashore Environmental Quali...

NCCOS scientist collects samples at Cape Lookout National Seashore adjacent to the abandoned town of Portsmouth, North Carolina. Credit: NOAA. NCCOS scientists have released a final report assessing the environmental ...

Global Study Determines Economic Value of Shellfis...

When practiced and managed well, shellfish and seaweed aquaculture can provide sustainable seafood and improve the surrounding environment. These kinds of aquaculture farms act as nursery habitats, increasing recruitment of ...

Scientists Use Land Use, Demographics Data to Mode...

The NOAA National Status and Trends Program (NST) monitors and characterizes the nation’s coastal waters at risk of contamination by anthropogenic inputs. NCCOS social scientists further characterize and model relationships ...

Data & Publications

A coupled physical-biological model of the Northern Gulf of Mexico shelf: model description, validation and analysis of phytoplankton variability

The Texas-Louisiana shelf in the Northern Gulf of Mexico receives large inputs of nutrients and freshwater from the Mississippi/Atchafalaya River system. The nutrients stimulate high rates of primary production in the river plume, which contributes to the development of a ...

A modeling study of physical controls on hypoxia generation in the northern Gulf of Mexico

The Louisiana shelf (LA shelf) in the northern Gulf of Mexico experiences hypoxic conditions every summer due to the combination of eutrophication and strong water column stratification. Here we use a three-dimensional circulation model coupled with a simple oxygen model ...

A Novel Antibody-Based Biomarker for Chronic Algal Toxin Exposure and Sub-Acute Neurotoxicity

The neurotoxic amino acid, domoic acid (DA), is naturally produced by marine phytoplankton and presents a significant threat to the health of marine mammals, seabirds and humans via transfer of the toxin through the foodweb. In humans, acute exposure causes ...

A Scenario and Forecast Model for Gulf of Mexico Hypoxic Area and Volume

For almost three decades, the relative size of the hypoxic region on the Louisiana-Texas continental shelf has drawn scientific and policy attention. During that time, both simple and complex models have been used to explore hypoxia dynamics and to provide ...

An Analysis of Chemical Contaminants in Sediments and Fish from Cocos Lagoon, Guam

As part of the NOAA Coral Reef Conservation Program (CRCP) jurisdictional priority gathering, local agencies in Guam identified Cocos Lagoon as an area potentially impacted by land-based sources of pollution. The US Coast Guard operated a Long Range Navigation (LORAN) ...

An Assessment of Contaminants of Emerging Concern in Chesapeake Bay, MD and Charleston Harbor, SC

NOAA’s National Status and Trends (NS&T) Mussel Watch Program conducted regional pilot studies to assess the magnitude and distribution of contaminants of emerging concern (CEC) in shellfish and sediment from different coastal zones. In 2015, oyster and surficial sediment samples ...

An assessment of nutrients, sedimentation, and total suspended solids (TSS) in the St. Thomas East End Reserves (STEER)

This is the fifth report from a project to assess land-based sources of pollution (LSBPs) and their effects, and to characterize the biological community with the St. Thomas East End Reserves (Steer) in St. Thomas, USVI. Here we summarize the ...

An Assessment of Polybrominated Diphenyl Ethers (PBDEs) in Sediments and Bivalves of the U.S. Coastal Zone

This report, which represents the first national assessment of polybrominated diphenyl ethers (PBDEs) in the U.S. coastal zone, shows that they are widely distributed. PBDE concentrations in both sediment and bivalve tissue correlate with human population density along the U.S ...

An integrated environmental assessment of the St. Thomas East End Reserves (STEER)

The St. Thomas East End Reserves, or STEER, is a collection of Marine Reserves and Wildlife Sanctuaries (MRWS) located on the southeastern end of the island of St. Thomas, U.S. Virgin Islands. With an area of approximately 9.6 km2 , ...

Analyses of the complete chloroplast genome sequences of two members of the Pelagophyceae: Aureococcus anophagefferens CCMP1984 and Aureoumbra lagunensis CCMP1507

Heterokont members of the Pelagophyceae form the massive brown tides that have continually plagued the coastal regions of the eastern U.S. seaboard and the Gulf of Mexico. To gain a better understanding of the photosynthetic competence that may be linked ...
