Persistent near real‐time passive acoustic monitoring for baleen whales from a moored buoy: System description and evaluation

Abstract: Managing interactions between human activities and marine mammals often relies on an understanding of the real‐time distribution or occurrence of animals. Visual surveys typically cannot provide persistent monitoring because of expense and weather limitations, and while passive acoustic recorders can monitor continuously, the data they collect are often not accessible until the recorder is recovered. We have developed a moored passive acoustic monitoring system that provides near real‐time occurrence estimates… Show more

“…Missed detection rates ranged from 34-64% on 15-min time scales and 17-24% on daily time scales. Compared to the automated method to estimate occurrence based on classified call counts described in Baumgartner et al (2013), the humanreview used here (after Baumgartner et al, 2019) yielded lower false detection rates for right and humpback whales, while fin whale false detection rates were equivalent (sei whales could not be evaluated by Baumgartner et al, 2013). Missed detection rates were higher for right and fin whales during the human review, but lower for humpback whales.…”

“…The DMON instrument Woods Hole Oceanographic Institution (WHOI) was integrated into the science bay of a Slocum glider model G2 for this study. The DMON has been described previously (Johnson and Hurst, 2007;Baumgartner et al, 2013Baumgartner et al, , 2019 and was configured in an identical manner as in previous studies with one exception. Baumgartner et al (2013) described the integration of the DMON in a Slocum glider model G1 where the hydrophones were mounted in an acoustically transparent urethane housing on the underside of the glider's science bay; in the G2 configuration, the hydrophones were mounted in a urethane housing on the topside of the glider's science bay (Figure 1).…”
