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 River or to the Chesapeake Bay. We compared predictions to ...

Models that help predict fecal coliform bacteria (FCB) levels in environmental waters can be important tools for resource managers. In this study, we used animal activity along with antibiotic resistance analysis (ARA), land cover, and other variables to build models that predict bacteria levels in coastal ponds that discharge into ...

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 ranged between 30?100 m in depth along the shelf, which ...

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 along the south edge of St. Thomas to the Eastern ...

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 estuarine regions using data-constrained salt- and water-balance computations (box model) ...

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 (Org-P) and detrital-apatite-P (Detr-P) to elucidate their reactivity and transformation ...

From a manager’s perspective, oftentimes the publicly held concerns related to small docks and piers are not really related to the environment. They may be more related to visual impacts and aesthetic concerns, a sense of over-development of the shore, or simply change. While individuals may hold personal aesthetic values ...

This Handbook has been prepared to inform you of the National Ocean Service’s history, philosophy, policies, and expectations of you and the NOS ...

Global oceans are undergoing acidification and deoxygenation, yet the concurrent effects of low oxygen and acidification on marine fish are unknown. This study quantified the separate and combined effects of low pH and low oxygen on 4 vital early life-history traits (time-to-hatch, hatching success, post-hatch survival, and growth) of 3 ...

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 ensonification, along with multibeam backscatter suitable for seafloor characterization in ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the first year of an ongoing scientific research mission on board NOAA Ship Nancy Foster. The purpose of this cruise was to support the National Oceanic and Atmospheric Administration?s research on the characterization of near shore and deepwater habitats (<1000m) of ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the third year of an ongoing scientific research mission on board NOAA Ship NANCY FOSTER. The purpose of this cruise is to support the benthic characterization of coral reef habitat in the U.S. Virgin Islands and Puerto Rico. The mission explored, ...

NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel NOAA Ship Nancy Foster and territory, federal, and private sector partners, conducted the twelfth year of an ongoing scientific research mission onboard NOAA Ship Nancy Foster, funded by NOAA?s Coral Reef Conservation Program. Data was acquired with a hull-mounted Reson 7125 ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the tenth year of an ongoing scientific research mission onboard NOAA Ship Nancy Foster. The objective of this project was to collect a multibeam bathymetric dataset with 100 percent seafloor ensonification, along with multibeam backscatter suitable for seafloor characterization in a ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the ninth year of an ongoing scientific research mission on board NOAA Ship Nancy Foster from April 3 to April 20, 2012. The objective of this project was to collect a multibeam bathymetric dataset with 100 percent seafloor ensonification, along with ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the second year of an ongoing scientific research mission on board NOAA Ship NANCY FOSTER. The purpose of this cruise was to support the benthic characterization of coral reef habitat in the U.S. Virgin Islands ...

The Center for Coastal Monitoring and Assessment (CCMA) completed its sixth 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% seafloor ensonification, along with multibeam backscatter suitable for seafloor characterization in high ...

The Center for Coastal Monitoring and Assessment (CCMA) conducted the fourth 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% seafloor ensonification, along with multibeam backscatter suitable for seafloor characterization in high ...

The Center for Coastal Monitoring and Assessment (CCMA) completed the fifth 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% seafloor ensonification, along with multibeam backscatter suitable for seafloor characterization in high ...
