B08_Attachment_3_-_Specifications_-_Whale_Movement_Parameters.pdf

This document is a detailed specification of humpback whale movement parameters in Alaska, based on published studies provided by C. Gabriele from Glacier Bay National Park in April 2024. The document presents precise behavioral metrics for humpback whales, including average dive times of 5.6 minutes (ranging from 1.2 to 12 minutes), surface blows of 3.2 (ranging from 2 to 10), and time between blows of 15 seconds (12 to 18 seconds). Additional key measurements include a swim speed of 2.4 knots (range 1 to 8 knots) and directional changes of 0.45 radians (0 to 0.8).

The summary description indicates that whales typically surface to make 2-3 blows separated by 12-18 seconds, remain at the surface for approximately 42 seconds total, and then dive for 5-12 minutes. During their movement, they travel at an average speed of 2.4 knots and change directions frequently, with an average directional shift of 0.45 radians between surfacing events. This specification appears to be an attachment to a federal contract opportunity (Solicitation Number 140P9725Q0024) for Whale Avoidance Training Modules in Glacier Bay, Alaska, issued by the Department of the Interior National Park Service Alaska Region.
