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 […]

The Craib Corer: Predicting Harmful Algal Blooms by Sampling the Seafloor

Forecasting harmful algal blooms is a complex endeavor involving a wide range of oceanographic disciplines. NCCOS scientists and sponsored researchers count the number of harmful algal bloom (HAB) resting stages or cysts that lie on the bottom of the ocean as one method to estimate the future occurrence of HABs. Scientists use a suite of […]

2015 Nancy Foster Caribbean Mapping Mission: Expedition Marks Twelve Years of Discovery

NCCOS is preparing to embark on its twelfth year of an ongoing scientific research mission on board the NOAA Ship Nancy Foster, funded by NOAA’s Coral Reef Conservation Program. The mission will combine methods of multibeam and fish sonar with video captured from an ROV (remotely operated vehicle) and environmental data collected from an autonomous glider from March 28 […]
