Using the second-generation Environmental Sample Processor to provide near real-time observations of harmful algae and assess biodiversity and ecosystem change

The second-generation Environmental Sample Processor (2G-ESP) is a sophisticated autonomous sensor platform and a key component of offshore observing efforts designed to mitigate the societal impacts of harmful algal blooms (HABs) in the Pacific Northwest. Deployed as part of a moored observatory, the 2G-ESP generates near real-time data on HAB organisms and the biotoxin domoic acid, providing critical HAB early warning and directly informing HAB forecasts and fisheries management decisions. In addition, the platform’s capacity to archive environmental DNA enables retrospective analyses of biodiversity and ecosystem change. These capabilities facilitate interdisciplinary scientific collaboration and information sharing, ultimately enhancing our collective understanding of HAB dynamics and broader ecosystem health.
