Observations of the areal extent of seasonal hypoxia over the Texas–Louisiana continental shelf from 1985 to 2010 are correlated with a variety of physical and biogeochemical forcing mechanisms. Significant correlation is found between hypoxic area and both nitrogen load (r2 ...

National Status and Trends (NS&T) Mussel Watch Program provides status of and temporal trends of coastal contaminant conditions. Bivalve tissues are analyzed for a suite of about 500 legacy and emerging chemicals of concern. In addition, bivalve tissues are assessed ...

National Status and Trends (NS&T) Mussel Watch Program provides status of and temporal trends of coastal contaminant conditions. Bivalve tissues are analyzed for a suite of about 600 legacy and emerging chemicals of concern. In addition, bivalve tissues are assessed ...

The occurrence of hypoxia in coastal oceans is a long-standing and growing problem worldwide and is clearly linked to anthropogenic nutrient inputs. While the need for reducing anthropogenic nutrient loads is generally accepted, it is costly and thus requires scientifically ...

The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions ...

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 ...

This dataset provides valuable baseline data on sediment chemical contamination for the St. Thomas East End Reserve (STEER), U.S. Virgin Islands (USVI). From 2010-2012, NOAA scientists collected samples as part of a larger, long-term monitoring National Status and Trends Program ...

This dataset contains results from the analysis of sediments for chemical contaminants including organic contaminants like hydrocarbons and pesticides, and inorganic contaminants like metals, along with an assessment of the benthic infaunal community in Salt River Bay National Historical Park ...

This dataset contains results from the monitoring of nutrients and turbidity in three rivers in the Manell watershed in southern Guam, which drain to the Achang Reef Flat Marine Preserve. The dataset contains a series of data tables and a ...

This dataset represents three years of water quality data collected in Vatia Bay, American Samoa. A standard suite of nutrient parameters (nitrate, nitrite, ammonium, urea, total nitrogen, orthophosphate, total phosphorus and silica), as well as tracers of human waste (sucralose ...
