With Second Workshop, NCCOS Continues Focus on Hyp...

Credit S. Brandt, OSU. Building on results of an initial 2017 workshop, a second advisory panel workshop concerning the effects of low dissolved oxygen in water (hypoxia) was held June ...

NOAA Forecasts Very Large ‘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—will be approximately ...

Scientists Use New Technique to Measure Size of Gu...

Every summer, the largest hypoxic zone in the U.S. forms in the northern Gulf of Mexico, resulting in widespread ecosystem and economic impacts. Determining, and then mitigating the size of ...

NPR Highlights New Hypoxia and Pacific Northwest D...

On October 28, 2018, the National Public Radio (NPR) Weekend Edition program featured a new NCCOS project that is tracking the extent and effect of hypoxia (low oxygen) on commercial ...

Data & Publications

Louisiana Hypoxia Surveys 2008: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2008 (NODC Accession 0069471)

Two sets of CTD data were taken during the 2008 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 ...

Louisiana Hypoxia Surveys 2011: Biological, chemical, and physical data collected off the coast of Louisiana as part of the Hypoxia Studies in the Northern Gulf of Mexico project in 2011 (NCEI Accession 0129417)

Two sets of CTD data were taken during the 2011 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 ...

Metabolic balance between ecosystem production and consumption

This chapter reviews research on ecosystem metabolism in coastal environments, focusing on the history of methods development, spatial/temporal variations in rates, controlling factors, and application of these methods to address diverse scientific questions. Essential concepts and widely used terms are ...

Modeling the influence of hypoxia on the potential habitat of Atlantic sturgeon (Acipenser oxyrinchus): a comparison of two methods

Management of marine and estuarine fish and shellfish would benefit from a numerical approach that quantifies the impacts of climate variability and eutrophication. We present a proof-of-concept habitat volume model that incorporates predictions from a 3-dimensional biophysical model. Using temperature, ...

Modeling the Population Effects of Hypoxia on Atlantic Croaker (Micropogonias undulatus) in the Northwestern Gulf of Mexico: Part 1 - Model Description and Idealized Hypoxia

We developed a spatially explicit, individual-based model to analyze how hypoxia effects on reproduction, growth, and mortality of Atlantic croaker in the northwestern Gulf of Mexico lead to population-level responses. The model follows the hourly growth, mortality, reproduction, and movement ...

Modeling the Population Effects of Hypoxia on Atlantic Croaker (Micropogonias undulatus) in the Northwestern Gulf of Mexico: Part 2 - Realistic Hypoxia and Eutrophication

Quantifying the population-level effects of hypoxia on coastal fish species has been challenging. In the companion paper (part 1), we described an individual-based population model (IBM) for Atlantic croaker in the northwestern Gulf of Mexico (NWGOM) designed to quantify the ...

Molecular Characterization and Hypoxia-Induced Upregulation of Neuronal Nitric Oxide Synthase in Atlantic Croaker: Reversal by Antioxidant and Estrogen Treatments

Neuronal nitric oxide synthase (nNOS) catalyzes production of nitric oxide in vertebrate brains. Recent findings indicate that endothelial NOS and reactive oxygen species (ROS) are significantly increased during hypoxic stress and are modulated by antioxidants. However, the influence of antioxidants ...

Movement of Juvenile Weakfish (Cynoscion regalis) and Spot (Leistomus xanthurus) in Relation to Diel-cycling Hypoxia in an Estuarine Tributary: Assessment Using Acoustic Telemetry

Fish movement and the spatial and temporal dynamics of hypoxia determine hypoxia exposure and the effect of poor water quality on nursery habitat function. Although water quality criteria for dissolved oxygen (DO) are well defined, hypoxia exposure of juvenile estuary-dependent ...

Narragansett Bay hypoxic event characteristics based on fixed-site monitoring network time series: Intermittency, geographic distribution, spatial synchronicity, and interannual variability

Low dissolved oxygen events were characterized in Narragansett Bay (NB), a moderate-size (370 km2) temperate estuary with a complex passage/embayment geometry, using time series from 2001 to 2006 at nine fixed-site monitoring stations. Metrics for event intensity and severity were ...

National Estuarine Eutrophication Assessment: Effects of Nutrient Enrichment in the Nation’s Estuaries

This report presents the results of a National Assessment Workshop held in August 1998 to address the problem of estuarine eutrophication. The assessment was based primarily on the results of the National Estuarine Eutrophication Survey, conducted by NOAA from 1992 ...
