New Recruits Comprise most of Coral Area Found in 2014

A completed analysis from the 2014 expedition to Pulley Ridge based on remotely operated vehicle (ROV) observations revealed significant areas of new coral growth. The findings were compiled from a total of 24 ROV dives to characterize the mesophotic coral reef ecosystems off the southwest coast of Florida and the Tortugas, and determined over 56.5 percent […]

NCCOS Leads Efforts to Prioritize Cyanobacterial Harmful Algal Bloom Research

In 2014 access to drinking water in Toledo, Ohio was shut down due to cyanobacterial harmful algal bloom (HAB) toxins from Lake Erie. The National Science Foundation and NOAA responded with a workshop,“Global Solutions to Regional Problems: Collecting Global Expertise to Address the Problem of Harmful Algal Blooms,” at Bowling Green State University, Bowling Green, OH, April 13-14, […]

Technology Transfer of Toxin Detection Methods to South Korean Researchers

Two researchers from the Korea Institute of Ocean Science & Technology (KIOST) visited the NCCOS Center for Coastal Environmental Health and Biomolecular Research (CCEHBR) laboratory in Charleston, SC for two weeks of intensive training on the use of mass spectrometry to detect several algal toxin classes, including domoic acid (DA), paralytic shellfish toxins (PSTs), and […]

New Partnerships in the Florida Keys Strengthen Early Warnings of Harmful Algal Blooms

A grant from the Ocean Reef Conservation Association (ORCA) to the Marine Resources Development Foundation enabled expansion of NOAA’s Phytoplankton Monitoring Network (PMN) monitoring sites in the Florida Keys. The Marine Resources Development Foundation has been an active volunteer group with PMN since 2012. With this ORCA grant and technical guidance from PMN, the Marine Resources […]

Gulf of Mexico Offshore Dead Zone Linked to Mississippi River Nutrient Inputs

Twenty-five years of NCCOS sponsored research shows that the offshore summer hypoxic (low-oxygen) “dead zone” in the Gulf of Mexico is strongly linked to nutrient loading from the Mississippi River. Physical forces (i.e., wind, waves, currents, temperature) play an equally strong role as biological variables (i.e., phytoplankton growth/decay, photosynthesis/respiration) in creating and maintaining Louisiana shelf hypoxia […]

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 […]

Puget Sound Harmful Algal Blooms Linked to Seasonal Patterns and Survival Probability

In order to predict blooms and prevent undue economic loss of commercial shellfish in Puget Sound, NCCOS has sponsored research investigating the seasonal patterns and mechanisms of bloom formation of Alexandrium, a dinoflagellate that contaminates shellfish and causes paralytic shellfish poisoning (PSP) in humans. The study shows Alexandrium survives and spreads in Puget Sound in response to […]
