Risk of Shellfish Toxicity Predicted by Temperature and Salinity

A new study shows that water temperature and salinity can indicate the likely occurrence of toxic Alexandrium blooms (a type of harmful algae) in the U. S. Pacific Northwest. As shellfish become contaminated with the toxins produced by these harmful algal blooms (HABs), researchers and shellfish managers can use these findings to predict shellfish toxicity, which causes illness or even […]

Research Gaps Identified to Improve Future Harmful Algal Bloom Forecasts

After a 2013 workshop at the University of Washington’s Friday Harbor Laboratories, NCCOS-sponsored researchers published a study in Harmful Algae addressing the current knowledge of climate change and how it could impact environmental conditions that favor harmful algal bloom (HAB) formation. The workshop gathered a diverse group of HAB researchers who summarized the state of knowledge and information gaps of the potential […]

National Coastal Ocean and Estuary Conference Provides Platform for NCCOS Research

The 23rd biennial Coasatal and Estuarine Research Federation Conference (CERF), held in Portland, Oregon this November, highlighted the scope of research sponsored by NCCOS including harmful algae and their toxins and ocean acidification and hypoxia (low dissolved oxygen) interactions. NCCOS exclusively hosted a major session and co-hosted a second major session with the NOAA Office of Oceanic […]

New Predictive Tool Helps Managers in Lake Michigan’s Green Bay

A new predictive management tool addresses an issue that confronts Wisconsin resource managers, farmers, environmentalists and fish scientists – too many nutrients, mainly phosphorus, from the Lower Fox River washing into Green Bay leading to hypoxia and harmful algal blooms. The model tool, developed by the Green Bay hypoxia and climate change project and funded by NCCOS’ […]

Emerging Techniques Help Guide Coral Reef Management

Although coral reefs are in rapid decline in most regions, new natural and social science research sponsored by NCCOS is helping to support successful coral reef management strategies and interventions. Recent and emerging molecular tools such as genomics (complete genetic mapping/DNA sequencing), proteomics (protein analysis), and transcriptomics (complete messenger RNA analysis) allow researchers to address […]

Association of Marine Lab Conference Features Caribbean Ciguatera Research

To raise awareness about a resurgence of Ciguatera Fish Poisoning (CFP) in the Caribbean and the current state of ciguatera research, NOAA’s National Centers for Coastal Ocean Science (NCCOS) led a special session on ciguatera at the Association of Marine Laboratories of the Caribbean 37th Scientific Conference in Willemstad, Curaçao, during the week of May […]

Oceanic Continental Margin Dead Zones Emerge as Threats to Coastal Waters

Declines in oxygen levels of coastal waters have accelerated in recent decades creating “dead zones” not only in more publicized nearshore areas but in open ocean offshore regions of the continental shelves and slopes. Once treated as separate phenomena and distinct fields of study, scientists now see offshore and coastal hypoxia as interconnected, resulting in […]

Sea Star Wasting Disease Discovered in Alaska

Researchers from NCCOS and the University of Alaska Fairbanks School of Fisheries and Ocean Sciences found evidence of sea star wasting disease in Alaska while surveying intertidal areas near NOAA’s Kasitsna Bay Laboratory. The team found the diseased sea stars during long-term monitoring surveys conducted under the Gulf Watch Alaska program at sites around Elephant […]
