A coast-wide surveillance program that identifies algal toxin exposure in marine wildlife populations.
Algal toxin exposure can impact many marine mammals, including dolphins, whales, sea otters, and sea lions. WARRN-West is a coast-wide surveillance program that identifies algal toxin exposure in marine wildlife populations. We monitor for domoic acid (the toxin responsible for Amnesic Shellfish Poisoning) and saxitoxin (the most potent toxin of the Paralytic Shellfish Toxins).
The sampling network consists of federal, state, public, private, and academic partners and the major marine mammal stranding networks on the US West Coast. We test all species of marine mammals and make the results available in near real-time.
In a complementary study funded by ECOHAB, we use a biomedical model (zebrafish) to find biomarkers indicative of chronic disease caused by domoic acid exposure. This marriage of the biomedical model and field exposed sentinel species help us develop effective biomarkers of disease. We can use these biomarkers to assess “at-risk” human and wildlife populations.
