Harmful algal blooms (HABs) are among the most dire ocean-related human health risks. They occur when single-celled algae in the ocean accumulate, often due to interactions between their swimming behavior and the movement and structure of the water column. In particular, he’s relying on a WHOI-developed solution for real-time detection of HABs in real time in his shellfish beds. This particular species can cause Amnesic Shellfish Poisoning (ASP) leading to permanent short-term memory loss. Brosnahan had been experimenting with a compact submersible camera system, the Imaging FlowCytobot (IFCB), to detect algal bloom species in the water.
