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 ...

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 ...

Hypoxia in Tropical Marine Ecosystems, the Underst...
A recent review article by NCCOS-supported researchers assessing the state of knowledge of hypoxia (low oxygen) in tropical ecosystems finds little information in comparison to what is known about 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 ...

NCCOS-supported researchers from the University of Florida and Smithsonian Marine Station paired water quality sensors with coral outplants to develop data-driven criteria for selection of restoration sites in the Florida ...
Combining Geostatistical and Mechanistic Models Im...
NCCOS-sponsored scientists combined two traditional, but often separate, modeling approaches to better characterize, track, and predict coastal hypoxia in the northern Gulf of Mexico. Their study found that “fused” geostatistical ...

NOAA Highlights Dead Zone Science at Hypoxia Task ...
The Mississippi River Gulf of Mexico Watershed Nutrient Task Force, otherwise known as the Hypoxia Task Force (HTF), held a virtual fall meeting from September 30 to October 1, 2020 ...
Lake Erie Hypoxia Forecast Helps Treatment Plant O...
Low dissolved oxygen (hypoxia) in a water body can certainly harm aquatic life, but it can also create problems for water treatment plant operators. Personnel have to respond quickly when ...

Hypoxia-induced shifts in nitrogen and phosphorus cycling in Chesapeake Bay
We investigated interactions between hypoxia and nutrient cycling in Chesapeake Bay using quantitative analysis of long?term monitoring data covering the periods 1965?1980 and 1985?2007. The data included vertical water column profiles of temperature, salinity, NH+4, PO3?4, and O2, as well ...
Improving methods and indicators for evaluating coastal water eutrophication: A pilot study in the Gulf of Maine
Study Goals and Objectives: 1) Improve existing nutrient-related eutrophication assessment methods, updating (from early 1990s to early 2000s) the eutrophication assessment for systems included in the study with the improved method. 2) Develop a human-use/socioeconomic indicator to complement the assessment ...
In situ, high-resolution time series of dissolved phosphate in Green Bay, Lake Michigan
In nearly every instance in which the environment has been sampled on a higher resolution in time or space, fundamental processes have come to light that were previously undetected or unobserved. In this study, an autonomous dissolved phosphate sensor was ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 1 Report: Characterization of Hypoxia
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 2 Report: Ecological and Economic Consequences of Hypoxia
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 3 Report: Flux and Sources of Nutrients in the Mississippi-Atchafalaya River Basin
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 4 Report: Effects of Reducing Nutrient Loads to Surface Waters within the Mississippi River Basin and the Gulf of Mexico
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 5 Report: Reducing Nutrient Loads, Especially Nitrate-Nitrogen, to Surface Water, Ground Water, and the Gulf of Mexico
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Integrated Assessment on Hypoxia in the Gulf of Mexico, Topic 6 Report: Evaluation of the Economic Costs and Benefits of Methods for Reducing Nutrient Loads to the Gulf of Mexico
As part of a process of considering options for responding to hypoxia, the U.S. Environmental Protection Agency (EPA) formed the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force during the fall of 1997, and asked the White House Office of ...
Landscape-Level Variation in Disease Susceptibility Related to Shallow-Water Hypoxia
Diel-cycling hypoxia is widespread in shallow portions of estuaries and lagoons, especially in systems with high nutrient loads resulting from human activities. Far less is known about the effects of this form of hypoxia than deeper-water seasonal or persistent low ...
