There is an urgent need to develop reliable biomarkers of environmental hypoxia exposure in marine organisms in order to assess the ecological impacts of the marked increase in coastal hypoxia worldwide. Full-length hypoxia-inducible factor HIF-1α and HIF-2α cDNAs were cloned ...

This study analyzed nearly ten years of acoustic telemetry monitoring at Gray’s Reef National Marine Sanctuary, to understand its role in fish movements along the U.S. Atlantic coast. Designated in 1981, Gray’s Reef lies 17 miles off the coast of ...

Habitat complexity plays a major role in determining the distribution and structure of fish assemblages in the aquatic environment. These locations are critical for ecosystem function and have significant implications for conservation and management. In this study, we evaluated the ...

We analyzed an ensemble of watershed models that predict flow, nitrogen, and phosphorus discharges. The models differed in scope and complexity and used different input data, but all had been applied to evaluate human impacts on discharges to the Patuxent ...

NCCOS scientists conducted an independent assessment within the US Virgin Islands from January 30 to February 13, 2017 to evaluate the thematic accuracy of a draft benthic habitat map of the South Eastern Puerto Rican Shelf. Sites in the area ...

NCCOS scientists conducted field operations from August 20 to September 2, 2016 in areas between 30?100 m in depth on the South Eastern Puerto Rican Shelf. The South Eastern Puerto Rican Shelf stretches off the East Coast of Vieques, PR ...

In May 2012, NOAA led a multiagency mission to conduct a comprehensive assessment of fish and benthic communities at depths between 1-100 feet (0.5-30 m) around the island of St. Croix ...

Regional, seasonal, and interannual variations of freshwater inputs, biogeochemical transformations, and pelagic-benthic interactions were examined in the Patuxent River estuary. Monthly rates of net biogeochemical production (or consumption) and physical transport of carbon, oxygen, and nutrients were calculated for 6 ...

Water, suspended-particles, and surface-sediment samples were collected from Green Bay, Lake Michigan, for the measurements of phosphorus (P) species, including dissolved/particulate-P, inorganic/organic-P, and five different forms of particulate-P, namely exchangeable- or labile-P (Ex-P), iron-bound-P (Fe-P), biogenic-apatite and/or CaCO3-associated-P (CFA-P), organic-P ...

The Center for Coastal Monitoring and Assessment (CCMA) completed its seventh year of an ongoing scientific research mission on board NOAA Ship Nancy Foster. The objective of this project was to collect a multibeam bathymetry dataset with 100 percent seafloor ...
