Hello All,

We are pleased to announce that the following paper has been published
online in Marine Mammal Science:

Incorporating tides into the acoustic ecology of humpback whales
Dawn R. Barlow*, Michelle EH Fournet*, Fred Sharpe

North Pacific humpback whales (Megaptera novaeangliae) migrate annually to foraging grounds in Southeast Alaska that are characterized by semidiurnal tidal cycles. Tidal activity is an important driver of marine mammal behavior on foraging grounds, but is often omitted in studies of acoustic ecology. To better understand the role of sound in this vocal species we investigated the influence of tidal height and direction on humpback whale nonsong calling behavior in Frederick Sound and described new call types for this population. The likelihood of detecting a call from the low©\frequency©\harmonic, pulsed, or noisy©\complex call classes was independent of tidal activity. The likelihood of detecting a call from the tonal call class, and a feeding call in particular, was 2.1 times higher during flood tides than during ebb tides (95% CI 1.1¨C4.4). This likely reflects an indirect relationship between humpback whale foraging and tides.

Please don't hesitate to contact myself (michelle.fournet at cornell.edu) or Dawn Barlow (dawn.barlow at oregonstate.edu) with any questions.
