Visiting the Canadian cousins of Monterey Bay’s sea otters

Since 1984, Monterey Bay Aquarium’s Sea Otter Program team has worked to understand and protect southern sea otters (Enhydra lutris nereis). The population has slowly recovered from near-extinction in the early 1900s to become an icon of California’s Central Coast. Northern sea otters (Enhydra lutris kenyoni) have a similar story on the Southwest Canadian Coast: After going locally extinct in the early 1900s, they’ve been reintroduced and are expanding their range.

 Today, the Hakai Institute is studying how the presence of sea otters is changing kelp forest ecosystems in a marine protected area along the British Columbia coast. This summer, Aquarium Sea Otter Research Coordinator Michelle Staedler and Senior Research Biologist Jessica Fujii traveled to Calvert Island to help monitor northern sea otters. Michelle shares her insights from the expedition.

The pilot banked the small plane, flying up a narrow waterway at the upper end of Calvert Island. Jessica and I saw below us a floating dock, several boats and red-roofed buildings nestled among the trees. This would be our home base for the next two and a half weeks.

Our destination: Hakai Institute’s Calvert Island Field Station, a coastal research facility 400 miles a northwest of Seattle. The only way to the island is by boat or float plane, weather permitting—but the frequent fog and storms don’t always cooperate.
