Water Quality Improvements Through Shellfish Aquaculture Highlighted in NOAA Science Seminar Series

A recent presentation highlighted a new NCCOS modeling study in Long Island Sound (LIS) and Great Bay Piscataqua Regional Estuaries (GBP) that focused on the water quality benefits of shellfish aquaculture. The presentation, “Eutrophication and Aquaculture; Shellfish can help the Bay!,”reported nitrogen removal estimates through cultivation of oysters equivalent to 1% of total nutrient inputs discharged […]

Expedition Marks Twelve Years of Discovery in the Caribbean

Scientists recently completed the 12th year of a research expedition to map seafloor habitats in the U.S. Caribbean aboard the NOAA Ship Nancy Foster. Researchers mapped nearly 200,000 underwater acres along St. Croix and St. Thomas, U.S. Virgin Islands and completed 35 remotely operated vehicle dives. Key findings include the identification of three seamounts rising 25 […]

Regional Water Management Practices Reduce Biscayne Bay Submerged Aquatic Vegetation

In subtropical Biscayne Bay, Florida, NCCOS research reveals decades of water management practices reduce freshwater flow, negatively impacting abundance and composition of the bay’s nearshore submerged aquatic vegetation (SAV) communities, fish, and crustaceans. Over the last 50 years, a massive water management system modified the hydrology of the South Florida watershed by altering the quantity, […]

Storm Surge and Sea Level Rise Models Improved by Innovative Measurement of Coastal Marsh Elevation

Coastal marsh elevation, a measurement used in models to predict impacts of sea level rise and periodic flooding from storm surge, is commonly determined by remote sensing methods that have been found to overestimate marsh platform height. In order to address this inaccuracy, known as a “saturation problem” caused by dense vegetation, NOAA’s National Centers of […]

NCCOS, Partners Improve Aquaculture Siting and Production in Puget Sound

NCCOS and partners are using computer modeling to determine the carrying capacity for shellfish aquaculture—and the related potential for nutrient removal—in South Puget Sound. The team’s methodologies and guidelines will be used to inform marine spatial planning activities locally and throughout the U.S., promoting sustainable shellfish aquaculture and providing a framework for addressing issues that commonly lead […]

Reef Fish Movements Tracked in USVI Monument to Assess Boundary Effectiveness

NCCOS and National Park Service (NPS) researchers are evaluating the boundaries of the Virgin Islands Coral Reef National Monument in Coral Bay, St. John relative to the home range of reef fish that the monument was conceived, in part, to protect. The team has tracked reef fish movements using surgically implanted acoustic transmitters and an […]

NCCOS Collaboration Explores Previously Unmapped Seafloor Habitats of the Channel Islands National Marine Sanctuary

Well over 50 percent of the Channel Islands National Marine Sanctuary seafloor has yet to be mapped or characterized at a level suitable for resource management. Recently on board the NOAA ship Bell M. Shimada, NCCOS and partners worked to reduce that number. On this mission, 82 square miles were mapped and identified as priority […]

Entangled Bottlenose Dolphin Calf Rescued in Florida

An NCCOS researcher working with National Marine Fisheries Service (NMFS) and regional organizations rescued a bottlenose dolphin (Tursiops truncatus) calf with monofilament fishing line wound about the tip of its rostrum near Lakewood Park, FL. The entanglement was first reported in mid-January, but as the calf grew the line cut deeper into its rostrum.  NMFS, in consultation […]
