Seasonal outbreaks of domoic acid poisoning are common along the California Coast. The toxin then transfers to predators such as sea lions and birds that prey on the fishcausing seizures, brain damage, and sometimes death. Please visit the web pages of those agencies for detailed information about the operational status of these products and contacts for questions about these products.įor more information see the Product Description Document. In 2022, the annual toxic algae season lasted a month beyond its typical window and, strangely, changed algae species in October. The algae produces a neurotoxin called domoic acid, which accumulates in fish such as sardines, anchovies, and squid. The minuscule organisms flourish in places where fresh and ocean water mix, although they can bloom, or explode in population, in any body. The Lake Erie Forecast is operated by NOAA/Centers for Coastal Ocean Science. Algae are plant-like organisms that come in a variety of shapes and sizes ranging from microscopic to large seaweed that may be over 100 feet long. Algae are tiny, but they can create big health problems. This web page is being provided as part of a multi-agency effort to provide information about and access to existing forecasts of Harmful Algal Blooms and other environmental information. Information/products are provided by NOAA/National Ocean Service, NOAA/Office of Atmospheric Research/GLERL, and NOAA/National Weather Service. The toxic algae bloom in Lake Erie that provoked last weekends tap water ban in Toledo, Ohiowhere nearly half a million people were told not to use water for drinking, cooking, or bathingis. Water temperature and winds (in magenta) are the averages for the western basin from the model.įor more info and links about harmful algal blooms including the observed bloom position and the vertical mixing forecast or to subscribe and receive forecast information by e-mail, please visit the NOAA Lake Erie HAB Forecast website. Most algae are harmless and are important parts of aquatic ecosystems, but some blooms produce toxins that pose a public health risk to people and animals. Black coloring indicates the absence of chlorophyll and grey color indicates areas with no data. According to the Florida Harmful Algal Bloom Task Force, in 2017. The modeled output does not contain clouds. Blue-green algae blooms are traditionally the most toxic and found in rivers, freshwater lakes, ponds. In California, the most alarming toxin is domoic acid, which can disrupt normal nerve signaling in. Potential for bloom movement is forecast in 3-dimensions with a hydrodynamic model using a hydrodynamic model with the satellite imagery. A bloom does not have to produce toxins in order to be harmful to the environment. Toxic algae can be fatal if a person drinks water from a bloom that contains certain toxins. This map models bloom position from date of satellite imagery to a minimum of 96 hours from date of publication, using water currents data from the Lake Erie Operational Forecast System (LEOFS).
