Humpback Whale Sound Production Recorded at Monterey Bay Aquarium Research Institute Monterey Accelerated Research System

Description

This record represents humpback whale detection from recordings at the Monterey Accelerated Research System (MARS) cabled observatory. MARS resides on the continental slope outside Monterey Bay, California at a depth of 890 m. It's location is in the center of Monterey Bay National Marine Sanctuary. Since 28 July 2015, MARS has supported nearly continuous sound recording at a sample rate of 256 kHz. Long term spectral averages with a resolution of 5 seconds/1 Hz were manually scanned using consistent intensity and contrast settings throughout the time-series. Visual detections were paired with model scores from the NOAA / Google humpback song detector (Allen et al., 2021). Aural verification of the recording was used when analysts were uncertain of the result. The analysis period for these detection is standardized across SanctSound sites to allow for direct comparison.These data were recorded at SanctSound Monterey Accelerated Research System between November 01, 2018 and October 31, 2020.

Sound Monitoring Unknown NOAA and the U.S. Navy are working to better understand underwater sound within the National Marine Sanctuary System. For the next few years, these agencies will work with numerous scientific partners to study sound within seven national marine sanctuaries and one marine national monument, which includes waters off Hawai'i and the east and west coasts. Standardized acoustic measurements are used to assess sounds produced by marine animals, physical processes (e.g., wind and waves), and human activities. Collectively, this information will help NOAA and the Navy measure sound levels and baseline acoustic conditions in sanctuaries. This work is a continuation of ongoing Navy and NOAA monitoring and research, including efforts by the NOAA Office of National Marine Sanctuaries. Open resource
