Singing Humpback Whale Recorded and Identified by Glacier Bay National Park Whale Biologists
October 3, 2011
This whale has never been observed as a singer, but has been sighted in the Glacier Bay area every year since 2000. The whale was at least four miles from the underwater hydrophone when the attached recordings were made, which gives you a good idea how loudly whales sing!
Humpback whale song is a mating related display that is primarily heard in the whales' tropical breeding grounds in the winter, but underwater sound monitoring that began in Glacier Bay in 2000 revealed that males begin to sing in late fall http://www.nsf.gov/pubs/2003/nsf03021/.

Cool noises heard on the park's underwater hydrophone:
PETERSBURG-AK (2009-12-30) On their late-fall research trip to study humpback whale and krill interactions in Seymour Canal, researchers with the National Oceanic and Atmospheric Administration made some exceptionally clear recordings of individual whale songs. KFSK Public Radio played some of these recordings for park wildlife biologist Chris Gabriele. She leads an underwater acoustic monitoring program at Glacier Bay National Park and she studies whale vocalizations. LISTEN

In 1899, an earthquake measuring 8.4 on the Richter Scale so shook the glaciers in Glacier Bay, the budding tourism industry nearly died. There was so much ice in the water from the shattered glaciers, visitors to Glacier Bay did not return to for over ten years.
