Hardened Shorelines Associated with Seagrass Decline in Southern Chesapeake Bay

A recent study sponsored by NCCOS found that submerged aquatic vegetation (SAV) in the saltier (and more southern) portions of Chesapeake Bay decreases in areas near hardened shorelines. Shoreline hardening is an attempt to stabilize coastal land and protect residential and commercial infrastructure along the coast by building structures, like bulkheads, to hold back the sea and prevent the […]

NOAA and Partners Evaluate Oyster Nutrient Removal as Best Management Practice for the Chesapeake

Scientists from NCCOS and the Northeast Fisheries Science Center were selected by the Chesapeake Bay Program Water Quality Goal Implementation Team, along with university researchers, federal, state and local resource managers, to serve on the Oyster Best Management Practice Expert Panel. The charge to the 13 member panel, conducted by the Oyster Recovery Partnership, is […]

Scientists Assess Impacts of Bioluminescent Algae on Chesapeake Bay Fisheries

Around mid-August, a bloom of the dinoflagellate Alexandrium monilatum appeared in lower Chesapeake Bay and its tidal tributaries. It is unclear whether the bloom originated there or was carried there by currents. Since it first appeared in the York River and at the oceanfront off Sandbridge Beach, the bloom has been observed miles into lower […]

Hardened Shorelines Make it Hard for Submerged Aquatic Vegetation

A recent NCCOS-funded study found that shoreline hardening, particularly riprap, has a negative effect on the abundance of submerged aquatic vegetation (SAV). Riprap, which is made up of rocks and boulders piled along the shoreline, is commonly used to prevent shoreline erosion, but once installed, alters the natural processes and composition of the land–sea interface. The […]

Science Informs Vote to Protect Mid-Atlantic Deep-Sea Corals

On June 10, NCCOS’s cross-NOAA partnerships and investment in carrying out spatial analyses of deep-sea coral ecosystems informed a near-unanimous vote by the Mid-Atlantic Fishery Management Council (MAFMC) to protect more than 38,000 square miles of seafloor, stretching from New York to Virginia, from bottom fishing activities. NCCOS played a lead role producing statistical models […]

NOAA Seminar Series Features Patuxent River Shellfish Aquaculture and Eutrophication Research

A scientist from NCCOS’s Center for Coastal Monitoring and Assessment described a modeling study in Chesapeake Bay region’s Patuxent River Estuary at the NOAA NOS Science Seminar Series on June 3, 2015. The presentation, titled “Shellfish Aquaculture: A Strategy for Eutrophication Mitigation in the Patuxent River,” reported nitrogen removal estimates through cultivation and harvest of oysters […]

Low Oxygen Conditions Increase Parasite Infections in Oysters

A study funded in part by NCCOS has found that diel-cycling hypoxia—daily cycling of high to very low oxygen levels—in shallow coastal waters increases parasite infections in eastern oysters (Crassostrea virginica). The project team tested and confirmed that diel-cycling hypoxia increases eastern oyster susceptibility to Perkinsus marinus infection, most likely by reducing the oxygen carrying capacity […]

Does Oyster Aquaculture Affect Nitrogen Loss From Sediments?

Off-bottom oyster aquaculture (Crassostrea virginica) is currently being investigated for possible effects on nutrient processes of surrounding sediments by  a Virginia Sea Grant Research Fellow, Abby Lunstrum, under the guidance of an NCCOS mentor. The research assesses whether, and to what extent, biodeposition from this type of aquaculture operations stimulates loss of nitrogen from the […]
