The research vessel Tiglax travels the Aleutians all summer, supporting research in the Alaska Maritime National Wildlife Refuge. The ship was in port last week, and its crew invited the public aboard for a tour celebrating the 100th anniversary of the refuge. KUCB’s Audrey Carlsen was there, and produced this audio postcard.
