Get this from a library! The acoustic environment and noise exposure of humpback whales in Glacier Bay, Alaska. [P R Miles; C I Malme; National Marine . A humpback whale making a simple “whup” call loses more of its acoustic habitat (%) than a singing humpback (wider frequency range, making it more detectable by other whales. Predicting the acoustic exposure of humpback whales from cruise and tour vessel noise in Glacier Bay, Alaska, under different management strategies.

Nearly all visitors to Glacier Bay arrive via motor vessels, yet the impact of the associated engine noise on humpback whale communication is unknown. Over the past 35 years extensive research on underwater sound has been conducted in Glacier Bay National Park and Preserve.
One of the measures that AIM produced was the cumulative sound exposure, or CSEL, which represents the total amount of noise that a whale is exposed to over the entire day. A key finding from this study was that cruise ship speed was the dominant factor affecting how much noise “whales” were exposed to in Glacier Bay. Predicting the acoustic exposure of humpback whales from cruise and tour vessel noise in Glacier Bay, Alaska, under different management strategies Article Full-text available. As noted in the NMFS Biological Opinion, the long term effects of chronic disturbance on the whales' survival and reproduction may never be known. To protect endangered humpback whales from chronic disturbance in Glacier Bay, vessel management regulations are designed to allow NPS. Sanctuary For Whales. Glacier Bay is a Humpback Whale sanctuary. In the park's waters, Humpback Whales benefit from some of the strongest protections found anywhere on our planet. Once in rapid decline, the number of whales spotted in Glacier Bay is growing every year. What's more, scientists have been studying Humpback Whales in Glacier Bay for decades. Thanks to this .

[C I Malme; P R Miles; P T McElroy; National Marine Mammal Laboratory (U.S.)]. May 24, · Male humpback whales sing loudly and for long durations during breeding season. A hundred years ago their voices did not have to compete with much man-made noise. These days they contend with underwater drilling, sonar, and the noise of thousands of cargo and passenger ships. This affects how and when they sing.
