The leading world venue for showcasing the latest research on oceans, coasts and lakes is the Association for the Sciences of Limnology and Oceanography (ASLO) Aquatic Sciences Meeting. The research programs sponsored by the NOAA National Centers for Coastal Ocean Science (NCCOS) lead management solutions for harmful algae, hypoxia and regional ecosystem-scale research. At the [...]

As part of a pilot initiative known as “beach hazard statements,” NOAA’s National Weather Service in Tampa Bay began to issue red tide warnings to beachgoers in an area where a bloom of algae is responsible for causing fish kills and breathing problems in people. While the announcement is new, the forecasts themselves are well [...]

NOAA researchers discovered how a harmful algal toxin called domoic acid targets the brain to induce seizures. Using a rat epilepsy model for the California sea lion, a species susceptible to poisoning by the toxin, they showed that it causes extensive damage to the olfactory bulb, a specialized brain region responsible for the perception of odors. [...]

A recently published finding may contribute to the development of a long-elusive affordable ciguatoxin detector, crucial for equatorial peoples worldwide at risk of contracting a severe type of seafood poisoning. While researching toxicity differences in the several species of tropical algae that cause ciguatera, researchers from the National Centers for Coastal Ocean Science and partners [...]

To better understand epileptic disease caused by an algal toxin in young California sea lions, researchers from the National Centers for Coastal Ocean Science exposed pregnant lab rats to the substance and studied its movement. In the adult rats, the toxin—known as domoic acid—enters the brain and surrounding fluid quickly and exits from the cerebrospinal [...]

A recently published research paper describes the minimum requirements for an effective harmful algal bloom (HAB) observing system for the U.S. west coast to mitigate HAB impacts. HAB observing systems provide early warning and forecasting of HAB events to guide decisions to close shellfish harvesting to protect human health, avoid mortality of protected species, and encourage aquaculture [...]

Back in July, scientists from the National Oceanic & Atmospheric Administration’s National Centers for Coastal Ocean Science (NCCOS) issued the first-ever seasonal harmful algal bloom (HAB) forecast for western Lake Erie at a press event at Ohio State University’s Stone Laboratory. Now, with the 2012 HABs season over, Dr. Jeff Reutter reflects on the successful prediction and looks ahead [...]

NOAA Fisheries now allows clam harvests in an area of Georges Bank off limits for the last 22 years to protect people from getting ill from algae toxins. Their decision centers on a two-part testing protocol that commercial fishermen and labs will use before bringing a catch to market. Once the haul arrives at the dock, [...]
