Bowhead Whale Study - Accoustics

The NSB DWM has conducted acoustic surveys in most years since 1984 (more on tacoustics data at NSB website). The acoustic data have been used to locate whales and make call counts through the spring migration and was used for abundance estimation. Acoustic information can also be used to examine changes in the spring migration including: a) documenting the beginning and end of the migration based on first and last dates of calls recorded, b) estimating the number of “singers” and distinct songs by year, c) measuring the total “acoustic energy” as an index of the numbers of whales, and d) determining if other whales are present in the lead (for example, gray and killer whales).
