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 […]

NCCOS Increases the Sonar Survey Accuracy of the NOAA Ship Okeanos Explorer

To ensure consistency in the quality of scientific echosounder and sonar data being collected by NOAA research ships, NCCOS has partnered with the Office of Exploration and Research to calibrate the scientific echosounder on the NOAA Ship Okeanos Explorer.  Researchers from NCCOS joined the Okeanos in Puerto Rico to conduct the calibration and train the […]

NOAA Partnership Improves Accessibility to NCCOS Echosounder Survey Data

Seafloor maps that include fishery echosounder data from the NCCOS-led coral reef ecosystem characterization surveys of the US Caribbean (2010-2014) are now available to the public through the National Geophysical Data Center Water Column Sonar Viewer.  The original objectives of the echosounder and sonar surveys were to map habitats of the seafloor and distribution of reef […]

New Fish Farm Siting and Management Practices Reduce Water Quality Impacts

Scientists with NOAA’s National Centers for Coastal Ocean Science (NCCOS) found that fish farm effects on dissolved oxygen and turbidity have been largely eliminated through better management, like using formulated feeds, minimizing feed waste, and properly siting farms in deep waters with flushing currents. The trend toward moving industrial-scale aquaculture into offshore waters is increasingly […]

Invasive Lionfish Web Portal Supports Community Management and Education

The newly released Invasive Lionfish Web Portal, developed by the Gulf and Caribbean Fisheries Institute in partnership with NOAA, supports the managment and control of lionfish in conservation areas along the Southeast coast of the U.S. and Caribbean. The invasive lionfish now threatens reef communities from North Carolina to South America with extreme impacts to […]

Fish Farming Improvements Reduce Environmental Impacts of Aquaculture

Advances in fish farming technology and management practices significantly decreased the environmental footprint and increased economic performance of aquaculture in the United States in the last forty years. Marine aquaculture in the United States represents an opportunity to provide healthy, domestic seafood, create jobs, and contribute to coastal economies, likely supplying most of the expected […]

NCCOS Improves Seagrass Coverage Estimates in North Carolina

NCCOS researchers applied an alternative method to improve classifying and calculating the extent of shallow seagrass ecosystems using digital aerial photographs in a recent study. The technique, linear spectral unmixing, is known for its success in classifying other shallow coastal habitats, particularly coral reefs, based on satellite multispectral imagery, but never seagrass. In this instance, aerial […]
