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.

Telephoto views of water in the bottom of Halema‘uma‘u taken during a helicopter lidar survey on July 25, 2019 (left), when the pond was first observed, and a USGS overflight on August 1, 2019 (right). The pond grew slightly in size and depth between the two dates; an "X" marks the same rock in both photos for comparison.
