Environmental Variables Influence Toxic Ciguatera Algae Growth and Distribution

A new study describes optimal growth conditions for several species and strains of the benthic marine dinoflagellate Gambierdiscus and highlights how these species and strains respond differently to varying levels of salinity, light, and temperature. These environmental factors, along with suitable seafloor habitat, predict the geographic distribution of Gambierdiscus. Gambierdiscus is a genus of tropical and subtropical […]

Can Mesophotic Coral Ecosystems Serve as Lifeboats for Shallow Reefs?

On May 24, 2016, the United Nations Environment Programme released a new report on mesophotic coral ecosystems (MCEs) during a coral reef media roundtable at the second session of the United Nations Environmental Assembly (UNEA-2) in Nairobi, Kenya. The document, Mesophotic Coral Ecosystems: A lifeboat for coral reefs?, edited by GRID-Arendal and NOAA, represents contributions […]

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 […]
