NCCOS Scientist Receives Prestigious Award

Dr. William Sunda will be awarded the elite honor of fellow in the Geochemical Society and the European Association of Geochemistry. The award will be presented in June at the Goldschmidt Conference in Sacramento, Calif., the annual meeting hosted jointly by both societies. The award honors outstanding scientists who have, over some years, made a […]

Evidence of Climate-related Algal Community Shifts off North Carolina

At least seven species of marine algae previously restricted to more tropical waters have expanded their range northward to the temperate reefs off North Carolina. Reports of seven other new algae species are under investigation to determine if they also represent a tropical shift in North Carolina’s algal flora. Researchers from the National Centers for […]

New Report Addresses Re-eutrophication and Hypoxia in Lake Erie

A new report aimed at Great Lakes policymakers calls for Lake Erie total phosphorus reductions almost 50 percent greater than previous recommendations. Recent total phosphorus reduction recommendations may not reduce hypoxia (low dissolved oxygen) as called for by the Great Lakes Water Quality Agreement undertaken by Canada and the United States. Reducing total phosphorus loading […]

Working to Reduce Toxic Blue-Green Algal Blooms in Chesapeake Bay

NCCOS-sponsored researchers recently explored several promising techniques to mitigate toxic cyanobacteria (blue-green algae) blooms in the Chesapeake Bay region. The team focused on sediment-flocculation, in which local sediments and commercial clays are combined with the flocculating compound chitosan to sink and bury Microcystis cyanobacteria blooms. Other techniques evaluated included post-bloom flushing and early spring deployment of […]

New Research Defines Origin and Dynamic Behavior of Gulf of Mexico Dead Zone

Reducing the size of the widespread area of hypoxia (low oxygen) in the northern Gulf of Mexico—known as the “Dead Zone”—represents one of the nation’s crucial water management challenges. Recent NCCOS-sponsored research has led to the development of a new tool to assess hypoxia formation and its response to key physical and biological drivers. Dr. […]

NCCOS Story Maps Garner the Attention of Esri Leadership

Two story maps produced by the National Centers for Coastal Ocean Science highlighting how NCCOS science connects oceans, coasts, and people were featured in a recent blog post by Esri chief scientist Dawn Wright. Esri is an international supplier of Geographic Information Systems (GIS). In her blog, “An Ocean of Story Maps,” Wright points to […]

NCCOS-developed Method for Toxins Detection Approved for Regulatory Testing of Shellfish in the U.S

Earlier this year, the Interstate Shellfish Sanitation Conference (ISSC) approved a new assay developed by the National Centers for Coastal Ocean Science (NCCOS) as an official method for identifying toxicity that could result in paralytic shellfish poisoning. This approval is the culmination of more than a decade of effort to find an alternative to live animal […]

Working to Understand and Remedy Dead Zone in Green Bay, Wisconsin

Since 2010, NCCOS-sponsored scientists have studied Green Bay, Wisconsin to better understand the source, dynamics, and controls of low oxygen (hypoxia) conditions that have resulted in a “dead zone” in the southern end of the bay. Considered key to understanding hypoxia in Green Bay, researchers have focused on the land surrounding the bay, which accounts […]
