Ep. 7: Calls of killer whales with Hannah Myers

Science writer Ned Rozell has accompanied researchers all over Alaska and given firsthand accounts of discoveries, triumphs and pitfalls of field work conducted in the Last Frontier. Through in-depth conversations, Ned gives voice to research stories ranging from volcanoes, earthquakes and auroras to climate change, anthropology, paleontology and wildfires. Any natural phenomena in Alaska and the people who study them are fair game. Ned has spent more than 25 years writing hundreds of science stories for the UAF Geophysical Institute's weekly column, the Alaska Science Forum: https://www.gi.alaska.edu/alaska-science-forum. New episodes drop on the first Tuesday of the month.
