Ciguatera fish poisoning (CFP) is the most common, non-bacterial, seafood illness. The condition is caused by toxins from the microalga Gambierdiscus, and can lead to diarrhea, paralysis, and, in worst ... Read More
Harmful algal blooms that disrupt and degrade coastal aquatic ecosystems are occurring with greater frequency. We developed a model that shows these events are not only the result of nutrient ... Read More
Adding carbon dioxide (CO2) to seawater raises the acidity of seawater, which can adversely affect marine life and fisheries. Coastal waters receive both atmospheric CO2 and CO2 from water pollution, ... Read More
Karenia mikimotoi is a toxic dinoflagellate alga with a cosmopolitan distribution and is a commonly reported red tide species. Blooms of K. mikimotoi have caused large fish and benthic invertebrate ... Read More
The lionfish is invasive to the Atlantic, Gulf of Mexico, and Caribbean. Credit: NOAA Scientists are investigating the prevalence of ciguatera toxins in invasive lionfish in response to interest in ... Read More
A recent study led by NCCOS and Stony Brook University concludes that rising ocean temperatures are expanding the geographical range of harmful algal blooms and intensifying the blooms themselves in ... Read More
In an effort to provide forecasting and detection products that empower communities to take action on HAB issues,a new publication in Phycologia documents the presence of Alexandrium fundyense and A. ostenfeldii in Alaska and ... Read More
Researchers from the Institut Louis MalardÃ¨ (ILM) in French Polynesia visited the NCCOS Center for Coastal Fisheries and Habitat Research (CCFHR) to gain expertise on working with Harmful Algal Bloom ... Read More
A PhD candidate from the French Research Institute for Exploitation of the Sea (IFREMER), Francesco Pisapia, is visiting the NCCOS Center for Coastal Fisheries and Habitat Research (CCFHR) for eleven ... Read More
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 ... Read More
Harmful algal blooms, particularly those that cause paralytic shellfish poisoning, pose a threat to human health, food security, and the economy of local communities in Alaska. There is a need ... Read More
Light micrograph of K. mikimotoi taken from a bloom sample. Starting in late Sept. 2013, a bloom of the phytoplankton Karenia mikimotoi began, progressed, and ultimately covered most of Kachemak ... Read More
The Harmful Algal Bloom - Forecasting Branch (HAB-FB) is a research group within the National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS) tasked with forecasting and monitoring HABs. One of the more effective ways to ... Read More
Global ocean temperatures are rising, yet the impacts of such changes on harmful algal blooms (HABs) are not fully understood. Here we used high-resolution sea-surface temperature records (1982 to 2016) and temperature-dependent growth rates of two algae that produce potent ... Read More
