Humpbacks of Glacier Bay

From 2014-2016, the Gulf of Alaska was hit by The Blob. A large mass of water that sat at a consistent record-high ocean temperature. A number of marine species saw a large population decline.

Humpbacks in Glacier Bay have been studied extensively since 1973. Individual whales are documented and identified by their dorsal fins and flukes. Each are unique. 2013 saw a return of 160 humpbacks to Glacier Bay, which was a record number since recording began. In 2014, the year the blob first showed itself, only 40 returned to The Bay. Some humpbacks have been returning to Glacier Bay for over 40 years.

The humpback population started to recover in Glacier Bay 2020. There were eleven calves in The Bay this year, where there were none for some of the blob years.

A curious side note: It has been reported that the humpbacks have thoroughly enjoyed having the waters of Glacier Bay almost to themselves. Or, at least without cruise ships. It has been documented that the whales have been much more vocal with each other with the absence of the large cruise ships.

No offense to anyone out there, but I am with the whales on this one. The lack of tourists has been peaceful.
