Navigation channels across the country require regular maintenance dredging to avoid infilling with sediments and becoming impassible. In an experimental strategy that is often referred to as “beneficial use,” sediments ... Read More
We work in partnership with other federal agencies and coastal states to conduct assessments of ecological condition and potential stressor impacts throughout our Nation’s estuaries, coastal-ocean waters, and NOAA protected ... Read More
Environmental conditions in the coastal zone are in decline due to increased coastal development and pollution. Using land-use modeling and environmental observations, we are determining the specific links between coastal ... Read More
NCCOS scientists completed a study of the soft-bottom habitats in offshore areas of the Florida Keys National Marine Sanctuary (FKNMS). While FKNMS is known for its coral reefs and extensive ... Read More
NCCOS researchers prepare to lower a grab sampler to collect benthic (bottom) sediments for analysis of physical properties, chemical contaminant levels, and enumeration of benthic fauna. Credit: C. Cooksey, NOAA ... Read More
A new report from NOAA's National Centers for Coastal Ocean Science (NCCOS) describes ecological conditions and stressors in sediments and biota in Gray's Reef National Marine Sanctuary (GRNMS), located off ... Read More
Researchers identified areas with low dissolved oxygen (DO) levels resulting in unhealthy benthic communities shown here in red, orange, and yellow. A new report is available summarizing the findings of ... Read More
Scientists have discovered evidence that contaminants from a Superfund site have made their way into samples collected in the Sapelo Island National Estuarine Research Reserve, 25 miles away. The researchers, ... Read More
The National Benthic Inventory’s Benthic Specimen Collection (NBSC) is an object-based scientific collection focused on marine and estuarine benthic macroinvertebrates. The collection consists of two main components: voucher specimens and sorted lots. View Product
A number of studies have shown that mobile, bottom-contact fishing gear (such as otter trawls) can alter seafloor habitats and associated biota. Considerably less is known about the recovery of these resources following such disturbances, though this information is critical ... Read More
Multiple indicators of water quality, sediment quality, and biological condition were used to assess the status of ecological condition of National Estuarine Research Reserve System (NERRS) sites in North Carolina, South Carolina, and Georgia relative to a suite of corresponding ... Read More
In June 2015, the NOAA National Centers for Coastal Ocean Science conducted an assessment of the status of ecological condition of unconsolidated, soft-bottom habitat and overlying waters at 30 sites from 11 – 99 m depth in targeted shelf areas ... Read More
In 1999, the Chesapeake Bay Program completed a survey of existing data on chemical contaminants and the potential for bioeffects in 38 tidal river systems of Chesapeake Bay. This review led to the identification of 20 areas for which there ... Read More
OpenNSPECT is a raster-based GIS model that estimates runoff, pollution and erosion in a GIS setting. NOAA’s National Centers for Coastal Ocean Science (NCCOS) has conducted a series of regional ecological assessments throughout many estuarine and coastal shelf areas of ... Read More
This cruise report is a summary of a field survey conducted along the continental shelf of the northeastern Gulf of Mexico (GOM), encompassing 70,062 square kilometers of productive marine habitats located between the Mississippi Delta and Tampa Bay, August 13 ... Read More
The overall purpose of the survey was to collect data to assess the status of ecosystem condition and potential stressor impacts throughout the region, based on these various indicators and corresponding management thresholds, and to provide this information as a ... Read More
This cruise report is a summary of a field survey conducted in coastal-ocean waters of the Mid-Atlantic Bight from Nags Head, North Carolina to Cape Cod, Massachusetts and from approximately 1 nautical mile (nm) of shore seaward to the shelf ... Read More
This cruise report is a summary of a field survey conducted in coastal-ocean waters off Florida from Anclote Key to West Palm Beach and from approximately 1 nautical mile (nm) offshore seaward to the shelf break (100 m). The survey ... Read More
This cruise report is a summary of a field survey conducted within the Stellwagen Bank National Marine Sanctuary (SBNMS), located between Cape Cod and Cape Ann at the mouth of Massachusetts Bay. The survey was conducted June 14 - June ... Read More
