Mr David Irons

I came to Alaska in 1976 from Penn State to work on a sea otter project on Attu Island, where I spent many cold hours underwater in leaky dry suits counting sea urchins and other benthic invertebrates. My attention began switching from marine mammals and the nearshore community to seabirds and the marine ecosystem. I have worked throughout Alaska on seabird foraging behavior and ecology and population changes related to food availability and climate change. Recently I have been working with seabird scientists from the circumpolar Arctic to investigate the effects of climate change at the circumpolar scale. I have also chaired the World Seabird Union from its inception until 2015.
