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 ...

NCCOS and NGI Lead First Fisheries Monitoring Work...

Monitoring dead zone oceanographic parameters and understanding how hypoxia impacts fisheries in the region is key to a successful Cooperative Hypoxia Assessment and Monitoring Program. Credit: LUMCON NCCOS and NOAA’s ...

Mitigation Strategies for Harmful Algal Blooms Spa...

New NCCOS-sponsored research describes a paradigm shift in our understanding of the conditions that control eutrophication (nutrient overenrichment) and harmful algal blooms (HABs) across the freshwater-to marine continuum, and offers ...

NCCOS and NGI Lead Seventh Annual Hypoxia Research...

NCCOS is working with the Northern Gulf Institute (NGI) and Gulf of Mexico State partners to develop a robust and sustainable Gulf of Mexico-wide monitoring program for hypoxia. At the ...

Modeling Coastal Hypoxia: NCCOS Sponsored Research...

A new book highlights NCCOS sponsored hypoxia modeling. It contains original research on numerical simulations of the patterns, controls, and effects of dissolved oxygen dynamics. The book, Modeling Coastal Hypoxia, ...

Multi-pronged Modeling Yields New Guidance to Miti...

Several NOAA-sponsored models took center stage at a recent meeting of the Mississippi River/Gulf of Mexico Hypoxia Task Force Coordinating Committee. Results from the models offered the task force new guidance ...

NCCOS Awards $1.7M to Harmful Algal Bloom and Toxi...

The National Centers for Coastal Ocean Science (NCCOS) awarded $1.68M (million) in Fiscal Year 2017 funding for nine research projects to identify conditions increasing bloom toxicity, model toxin movement from ...

Study Provides Nutrient Reduction Targets to Reach...

The Mississippi River/Gulf of Mexico Hypoxia Task Force (HTF) has made major strides in reducing point source nutrient pollution in the Gulf of Mexico watershed, and had some success in mitigating nonpoint ...

Natural and human-induced hypoxia and consequences for coastal areas: synthesis and future development

Hypoxia has become a world-wide phenomenon in the global coastal ocean and causes a deterioration of the structure and function of ecosystems. Based on the collective contributions of members of SCOR Working Group #128, the present study provides an overview ...

Numerical Modeling of Hypoxia and Its Effects: Synthesis and Going Forward

Numerical models can provide the needed information for understanding hypoxia and ensuring effective management, and this book provides a snapshot of representative modeling analyses of hypoxia and its effects. In this chapter, we used the modeling and analyses across the ...

Nutrient budgets and management actions in the Patuxent River estuary, Maryland

Multi-year nitrogen (N) and phosphorus (P) budgets were developed for the Patuxent River estuary, a seasonally stratified and moderately eutrophic tributary of Chesapeake Bay. Major inputs (point, diffuse, septic, and direct atmospheric) were measured for 13 years during which, large ...

Optimizing resource use efficiencies in the food-energy-water nexus for sustainable agriculture: from conceptual model to decision support system

Increased natural and anthropogenic stresses have threatened the Earth’s ability to meet growing human demands of food, energy and water (FEW) in a sustainable way. Although much progress has been made in the provision of individual component of FEW, it ...

Oxygen - Dynamics and biogeochemical consequences

Dissolved oxygen is a keystone molecule that is involved in the production, consumption, and cycling of organic matter and inorganic elements in the aquatic environment. The majority of multicellular plants and animals in coastal aquatic ecosystems require oxygen for proper ...

Physical (Hydrography), chemical (CTD), and biological (Water Quality) processes of the Texas-Louisiana continental shelf, 2012 (NCEI Accession 0162101)

Two sets of CTD data were taken during the 2012 surveys of the Louisiana continental shelf—Transect C off Terrebonne Bay and Transect F off Atchafalaya Bay and the 2012 Shelfwide Hypoxia cruise. Hydrographic data were obtained with the LUMCON SeaBird ...

Physical (Hydrography), chemical (CTD), and biological (Water Quality) processes of the Texas-Louisiana continental shelf, 2013 (NCEI Accession 0162440)

Two sets of CTD data were taken during the 2013 Shelfwide Hypoxia cruise off 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 ...

Physical (Hydrography), chemical (CTD), and biological (Water Quality) processes of the Texas-Louisiana continental shelf, 2014 (NCEI Accession 0161219)

Two sets of CTD data were taken during the 2014 Shelfwide Hypoxia cruise off 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 ...

Physical Drivers of the Circulation and Thermal Regime Impacting Seasonal Hypoxia in Green Bay, Lake Michigan

The physical processes that drive the circulation and the thermal regime in the bay largely control the duration and persistence of hypoxic conditions in Green Bay. A review of previous studies, existing field data, our own measurements, hydrodynamic modeling, and ...

Physical, chemical, and biological data collected in the Gulf of Mexico from 02 Feb 2010 to 28 Oct 2010 (NODC Accession 0117436)

Two sets of CTD data were taken during the 2010 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 ...
