Operational Gulf of Mexico Hypoxia Monitoring
The Gulf of Mexico hypoxia monitoring cruise is an annual shelf-wide survey of the Gulf's hypoxic area (i.e., “dead zone”) and the survey is the metric used by the interagency ...
Shallow Water Hypoxia: Tipping the Balance for Ind...
We are investigating the impacts of extreme daily fluctuations in oxygen and pH on fish and invertebrates in the Chesapeake Bay. The modeling tools we produce will improve the ability ...
Synthesis and Integrated Modeling of Long-Term Dat...
We are integrating existing data sets collected in the Northern Gulf of Mexico to study hypoxia impacts on coastal ecosystems and associated fisheries. We are using probabilistic, data-centric modeling to ...
Tracking the Extent and Effect of Hypoxia on Comme...
Low oxygen or hypoxic zones have increased in the Pacific Northwest. We are working with Dungeness crab fishermen in Oregon to deploy dissolved oxygen sensors on commercial crab pots to ...
Transitioning to Operations NOAA Supported Statist...
The Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) mandates the development of scientific tools for natural resource managers to address hypoxia in coastal ecosystems. In response, NCCOS ...
User-Driven Tools to Predict and Assess Effects of...
We are developing user-friendly, management-scale forecasting tools and quantitative indicators for hypoxia impacts on the Northern Gulf of Mexico ecosystem. We will assess minimum data needs to ensure these forecasts ...
Using Linked Models to Predict Impacts of Hypoxia ...
We are linking a suite of well-established models to quantify fish and shrimp population responses to combinations of nutrient loadings and planned river diversions. Our scenario analyses include different land-use ...

NOAA Ecological Forecast Helps Solve Mystery in La...
Residents of several northeast Ohio Lake Erie towns were surprised by a strong, foul smell during the first days of September. The residents, fearing a dangerous gas leak, called their ...
Coral Bleaching May be Induced by Hypoxia
NCCOS-supported researchers found low oxygen (hypoxia) led to coral bleaching, mass coral mortality, and changes in the microbial community on a Caribbean coral reef. In 2017, hypoxia was detected on ...
Larger than Expected Summer ‘Dead Zone’ Measured i...
Map of measured Gulf hypoxia zone, July 25–31, 2021 (LUMCON/NOAA). Red area denotes 2 mg/L of oxygen or lower, the level which is considered hypoxic, at the bottom of the ...
NOAA Announces FY22 Multi-stressor Federal Funding...
A leather sea star (Dermasterias imbricata) clings to a rock at the Outer Pinnacles. Purple urchins and even a rock scallop can be seen in this colorful display of life ...
Bacterial Removal of Nitrogen, Methane from Gulf D...
NCCOS-supported researchers have determined the natural removal rates of nitrogen and the potent greenhouse gas methane from Louisiana's coastal waters. The study investigated patterns of pelagic denitrification (bacterial conversion of ...
Building Partnerships to Track Hypoxia in Marine E...

NOAA Forecasts Average ‘Dead Zone’ for Gulf of Mex...
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 ...
Temperature and Oxygen Tolerances of Marine Specie...
NCCOS-supported researchers found that marine organism geographic distributions are best predicted by measuring temperature and dissolved oxygen together. Temperature and oxygen are closely linked in the physiology of marine animals ...
Fishing for Hypoxia

Impacts of Hypoxia on Marine Life Neglected, Thoug...
Map shows coastal sites where anthropogenic nutrients have exacerbated or caused oxygen declines to <2 mg/L (red dots), as well as ocean oxygen-minimum zones at 300 meters of depth (blue ...
