High-tech Armada Links Toxic Algal Blooms and Nutrients from Sewage off Southern California

Last month, NCCOS-funded scientists deployed two Environmental Sample Processors, two research vessels, five autonomous underwater vehicles, and five drifters in the ocean around San Pedro Bay, off Southern California, seeking signs of harmful algal blooms (HABs). Not long after deployment, this high-tech armada detected a large phytoplankton bloom that included the diatom Pseudo-nitzschia and its […]

Underwater Robots Detect Toxic Algae off Southern California

Two autonomous underwater robots deployed in San Pedro Bay off southern California have detected the diatom¬†Pseudo-nitzschia¬†and its potent neurotoxin domoic acid. This may signal the initiation of a harmful algal bloom along the coast that could impact a variety of wildlife and fishery resources. The robots, known as Environmental Sample Processors, are essentially underwater, molecular […]

High Tech Sensors Used to Investigate Harmful Algal Bloom ‘Hot Spots’ in California

NCCOS scientists and their partners from the Monterey Bay Aquarium Research Institute (MBARI) are investigating the causes of Pseudo-nitzschia blooms and toxicity in Monterey Bay, Calif. from Sept. 5 to Oct. 10. Under the right conditions, some Pseudo-nitzschia produce domoic acid, a potent neurotoxin. Domoic acid accumulates in fish and shellfish, has caused bird and […]
