NCCOS Projects at the Forefront of Numerical Estua...

Scientists' use of simulation models has increased during the past several decades as a widely accepted tool for investigations into estuarine dynamics. A recently published scientific review paper, authored by ...

2016 Ocean Sciences Meeting Showcases NCCOS Resear...

The 2016 Ocean Sciences Meeting this past winter featured the research of NCCOS scientists and sponsored principal investigators. Topics included ocean acidification, hypoxia, blue carbon, and harmful algal blooms. NCCOS ...

Envisioning a Plankton Imaging Network to Address ...

In mid-January, 2016, NCCOS funded investigators from Texas A&M University and the Woods Hole Oceanographic Institution convened a group of scientists and managers to produce a first-ever consensus vision for ...

NOAA Environmental Cooperative Science Center Stud...

A graduate student at University of Texas-Rio Grande Valley, Leticia Contreras, recently completed a month-long stay at NOAA'sCenter for Coastal Fisheries and Habitat Research in Beaufort, NC. Contreras worked with ...

New FY 2016 Research Funding Opportunity Available...

NCCOS has created a funding opportunity for Fiscal Year 2016 for two, national competitive hypoxia programs: the Northern Gulf of Mexico Ecosystems and Hypoxia Assessment Program (NGOMEX), and the Coastal ...

NCCOS Sponsors 20 New Research Projects

NCCOS awarded nearly $4.5 million in new research grants while maintaining sponsorship of 42 continuing projects during 2015 for a total of $8.2 million in funding for innovative research. All ...

Workshop Develops Linkages between NOS and Environ...

Last week, the NCCOS Charleston laboratories hosted a workshop to develop linkages between the National Ocean Service (NOS) and NOAA's Environmental Cooperative Science Center (ECSC) that will increase science capacity ...

New Technology Documents Rapid Phytoplankton Respo...

A scientific study funded by NCCOS's ECOHAB program, shows phytoplankton community structure changing rapidly, often by the hour, as tropical cyclones pass by. A revolutionary sampling instrument, the Imaging FlowCytobot ...

The Future of Algae Bloom Monitoring Technology

Technology developed with NCCOS funding is rapidly advancing harmful algal bloom (HAB) monitoring capabilities nationwide. These cutting edge detection tools are now commercially available and transitioning them to sustained management ...

NCCOS Community Well-being Data Now Available

In August, an NCCOS collection of community well-being data for the Gulf of Mexico went live on NOAA's Gulf Data Atlas. The Gulf of Mexico Coastal Community Well-being Data incorporates ...

Responses of carbonate system CO2 flux to extended flooding in a semiarid subtropical estuary

Globally, estuaries are considered important CO2 sources to the atmosphere. However, estuarine water carbonate chemistry and CO2 flux studies have focused on temperate and high latitude regions, leaving a significant data gap in subtropical estuaries. In this study, we examined ...

Responses of the coastal phytoplankton community to tropical cyclones revealed by high-frequency imaging flow cytometry

To investigate the response of a subtropical coastal phytoplankton community to tropical cyclones, we utilized high temporal resolution (hours) data from the Imaging FlowCytobot (IFCB) deployed in the Gulf of Mexico. In 2010, four tropical cyclones (two during June–July and ...

Seafood Prices Reveal Impacts of a Major Ecological Disturbance

Coastal hypoxia (dissolved oxygen ? 2 mg/L) is a growing problem worldwide that threatens marine ecosystem services, but little is known about economic effects on fisheries. Here, we provide evidence that hypoxia causes economic impacts on a major fishery. Ecological ...

Simulating the effects of phosphorus limitation in the Mississippi and Atchafalaya River plumes

The continental shelf of the northern Gulf of Mexico receives high dissolved inorganic nitrogen and phosphorus loads from the Mississippi and Atchafalaya rivers. The nutrient load results in high primary production in the river plumes and contributes to the development ...

Skill assessment of a hydrodynamic model of circulation over the Texas-Louisiana continental shelf

A numerical hydrodynamic simulation of the Texas-Louisiana continental shelf circulation is compared with hydrographic and moored observations of temperature, salinity, and current velocity. The spatial and temporal structure of the model error suggests that the model is able to reproduce ...

Small Spatial Scale Variation in Fish Assemblage Structure in the Vicinity of the Northwestern Gulf of Mexico Hypoxic Zone

Seasonal hypoxia [dissolved oxygen (DO)???2 mg?l?1] occurs over large regions of the northwestern Gulf of Mexico continental shelf during the summer months (June–August) as a result of nutrient enrichment from the Mississippi–Atchafalaya River system. We characterized the community structure of ...

Spatial-dynamics of Hypoxia and Fisheries: The Case of Gulf of Mexico Brown Shrimp

We analyze the Gulf of Mexico brown shrimp fishery and the potential impacts of a large seasonal area of hypoxia (low dissolved oxygen) that coincides with the peak shrimp season. A spatial-dynamic bioeconomic simulation embeds three biological impacts on shrimp: ...

Stable isotopes in mollusk shells as indicators of benthic respiration and freshwater penetration on the Texas-Louisiana Shelf

To investigate the potential for mollusks to serve as proxies for benthic respiration and hypoxia in the Gulf of Mexico (GOM), five gastropod (Conus austini Rehder and Abbott, 1951 and Strombus alatus Gmelin, 1791) and five bivalve (Pteria colymbus Röding, ...

Texas Coastal Hypoxia Linked to Brazos River Discharge as Revealed by Oxygen Isotopes

Hypoxic conditions in the coastal waters off Texas (USA) were observed since the late 1970s, but little is known about the causes of stratification that contribute to hypoxia formation. Typically, this hypoxia is attributed to downcoast (southwestward) advection of waters ...

The New Fisheries Economics: Incentives Across Many Margins

New research in fisheries economics addresses incentives across many margins. These margins include within-season effects, incentives to harvest different ages and sizes of fish, responses to ecological disturbances, spatial choices, and multispecies interactions. Even developments in global seafood markets are ...
