Northern Fulmars, Black-legged Kittiwakes, and Common Murres have all been tested for and contained harmful algal bloom (HAB) toxins in Alaska. Since 2015, the USGS has worked with a variety of stakeholders to develop testing methods and research projects to better understand the geographic extent, timing and impacts of algal toxins in Alaska marine ecosystems.
