    The National Centers for Coastal Ocean Science deliver ecosystem science solutions to sustain thriving coastal communities and economies. We provide coastal managers the information and tools they need to balance society's environmental, social, and economic goals. Site visits, regional workshops, and regional reports will be completed for the Gulf of Mexico, and West Coast in A national assessment report of the status and health of the nation’s estuaries will be developed from the survey results. In addition, an “indicator” of ecosystem health will also be published. Both national products.

The report summarizes the estimated relative susceptibility and estimated status of 23 estuaries in the Gulf of Mexico with respect to nutrient-related pollution. It is the second of a series of reports being developed to assist the U.S. EPA implement its Near Coastal Waters Program and National Estuary Program.

Susceptibility and status of Gulf of Mexico estuaries to nutrient discharges: summary report / By Heather Quinn and NOAA/EPA Team on Near Coastal Waters. Abstract. Mode of access: Internet Topics: Coasts, Waste disposal in the ocean, Estuarine.

The Ecological Condition of Estuaries in the Gulf of Mexico You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more. The Ecological Condition of Estuaries in the Gulf of Mexico (PDF) (73 pp, 5 MB, JulyEPA R). Susceptibility and Status of Gulf of Mexico Estuaries to Nutrient Discharges.

Silver Spring, of Oceanography and Marine Assessment. Metadata: The variable DCP is a calculated variable estimating the dissolved concentration potential of a pollutant as a function of pollutant load. Mexico has established 17 natural protected areas in the southern Gulf of Mexico and Yucatan to enhance sustainable management in the region.

In this chapter we review the structure and functioning of this regional coastal system, describe human impacts, review sustainable management of the area, and discuss the potential impacts of climate change.

The Gulf of Mexico is the ninth largest body of water in the world, and it is recognized as 1 of 64 Large Marine Ecosystems by the U.S. National Oceanic and Atmospheric Administration (NOAA) (Kumpf et al.

).Economically and ecologically the Gulf is one of the most productive and important bodies of water (Tunnell ; Fautin et al.

; NOS/NOAA ; Yoskowitz et al. ), occupying a. The sediment quality index for the collective NEP estuaries of the Gulf of Mexico region was rated as fair to poor with 18 % of the estuarine areas rated as either fair or poor for the sediment quality indicator (Figures and ).

As before, the sediment quality index was a composite indicator based on sediment toxicity, contaminants, and. Few gulf estuaries have low water clarity (Fig. • Estuaries are characterized by gradients in salinity from near fresh water at the mouths of tributaries to near marine at the mouth of the estuary.

Gulf of Mexico estuaries are predominantly polyhaline (more than 18 ppt) during the summer months (Fig. The Gulf of Mexico Regional Ecosystem is home to estuaries and coral reefs, supporting recreational and commercial fisheries, such as shrimp and red snapper.

Oil and gas platforms extract fossil fuels from reserves in the Gulf, but heavy pollution has led to harmful algal blooms and the hypoxia zone, which threaten this region’s resources. The Gulf of Mexico is a truly unique body of water. It is the ninth largest body of water on the planet and is home to nearly 49 different species of shark.

The Gulf of Mexico has a broad range of ocean ecosystems from shallow reefs to sea forests and has both shallow coastlines and deep ocean waters reach ft (4, m).

The Mobile Bay estuary is located in South Alabama and extends from the Mobile River Delta to the coastal waters of the Gulf of freshwater discharge (average flow = m 3 s −1) from the Mobile Bay watershed ranks fourth among watersheds in the continental United to the shallow nature of Mobile Bay (average depth = 3 m), freshwater discharge exerts.

Rebich, Richard A., Natalie A. Houston, Scott V. Mize, Daniel K. Pearson, Patricia B. Ging, and C. Evan Hornig, Sources and Delivery of Nutrients to the. The Southern Gulf of Mexico (SGoM) receives the discharges of the Grijalva-Usumacinta river system (GURS), the second-largest river of the Gulf of Mexico after the Mississippi (Yáñez-Arancibia.

Several years later (), EPA and NOAA published a study “Susceptibility and Status of Gulf of Mexico Estuaries to Nutrient Discharges”. Twenty-three estuaries in the Gulf of Mexico were examined for rate and volume of freshwater inflow and the ability to flush.

Not. In this sense, the SLE is similar to a number of tropical and subtropical estuaries in Australia (Eyre ), Brazil (Abreu et al. ), and the Gulf of Mexico (Lehrter ), in which nutrient. In addition to land use and nutrient sources, delivery of nutrients to the Gulf by State or sub-basin (as described above) are controlled by hydrology and watershed characteristics.

In total, only about 15% of the nitrogen and phosphorus ultimately reach the northern Gulf of Mexico. Overabundance of nutrients from freshwater inputs to the northwestern Gulf of Mexico and its coastline continues to be a major cause for concern.

The most prominent and well documented issue is hypoxia and degradation of aquatic resources along the inner continental shelf of the Gulf of Mexico off the coasts of Louisiana and Texas.

discharges. - In the northern Gulf of Mexico (Fig. 2), climate driven variations in the Mississippi River fluxes of freshwater & nutrients strongly influence the areal extent & severity of hypoxia.

The Gulf of Mexico is a vast natural resource encompassing the coastal areas of western Florida, Alabama, Mississippi, Louisiana, and Texas, as well as a portion of Mexico. Many estuaries flow into the Gulf of Mexico and serve as nursery grounds for fish, habitat for a wide variety of wildlife, shipping routes, and a source of recreation.

The Gulf of Mexico Branch (Gulf Branch) works with the Gulf of Mexico Fishery Management Council (Gulf Council) to manage fisheries in the Gulf of Mexico. The Gulf Council develops management measures through fishery management plans (FMPs) for key marine species.

The Gulf Branch puts in place the resulting regulations. Gulf of Mexico, Spanish Golfo de México, partially landlocked body of water on the southeastern periphery of the North American continent. It is connected to the Atlantic Ocean by the Straits of Florida, running between the peninsula of Florida and the island of Cuba, and to the Caribbean Sea by the Yucatán Channel, which runs between the Yucatán Peninsula and Cuba.Introduction.

Anthropogenic nutrient loading has resulted in increased incidence and adverse impacts of plankton blooms in coastal systems around the world (Hallegraeff et al.

).Cultural eutrophication caused by nutrient inputs is thought to be the most widespread pollution problem of U.S. estuaries (Kennish).Howarth et al. () reviewed effects of excess nutrients on coastal.The Gulf of Mexico resembeles a large pit with a broad shallow rim.

It is a Mediterranean-type sea and is bordered by the United States to the north (Florida, Alabama, Mississippi, Louisiana, Texas), five Mexican states to the west (Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan), and .
