| Abstract | Shallow, low-activity, low-biosonar parabolic-shaped dives were observed in biologging data from tagged harbor porpoises in Danish waters and identified as potential sleeping behavior. This behavioral state merits consideration in assessing the context for noise exposure and passive acoustic monitoring studies. Similar dives have also been reported for other cetacean species. The existence of low-level bioacoustic dives that may represent that sleeping has implications for the mitigation of not only noise exposure but also of bycatch as well as legal repercussions given the protected status of sleeping, as a part of resting, under many legislative regimes. |
