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 […]

NCCOS and Partners Assess Using Shellfish Aquaculture to Improve Water Quality in Chesapeake Bay

Researchers are exploring the role oyster aquaculture may be playing in improving water quality in the Chesapeake Bay. On July 16, 17, and 23, 2014,  the researchers made visits to three Chesapeake Bay oyster growers to discuss their culture practices, to view their lease areas, and to share information about this joint project. The project also  involves development […]

Festival Goers Learn About River Stewardship

Last month’s River and Roots Festival in Berryville, Va., gave the public a chance to hear live music, eat local food, and learn how to be better stewards of the Shenandoah River. Staff from NOAA’s National Centers for Coastal Ocean Science and Office of Response and Restoration led a river awareness workshop to teach festival goers […]

NOAA Harmful Algae Research Featured at Interstate Seafood Seminar

NCCOS’s Dr. Quay Dortch was a featured speaker at the 66th Interstate Seafood Seminar conference during a session devoted to harmful algal blooms (HABs) and their impacts on shellfish safety and shellfish production. Dortch discussed NOAA’s HAB programs and how they enhance state rapid response and build a national capacity to minimize HAB impacts. She also […]
