Calls were detected automatically using Triton's Fish Detector. Recordings were first decimated to a sample rate of 2 kHz. The fish detector filtered the time series between 100 and 950 Hz, and computed cross-correlation between the envelope of a filtered example call and 75s of the envelope of the filtered time series. To detect signals within varying background noise, we used a floating threshold of the median cross correlation value over the current 75 s of data, with a threshold offset of 2e-9 above the median. Detections were evaluated if they reached above this threshold. Consecutive calls were required to have a minimum time gap of 0.5 s to be detected separately. RMS received level was computed over the potential detection period and a time series of the length of the bocaccio call template before and after the detection. Detections were considered false and discarded if the signal-to-noise ratio between the detection period and the timeseries before and after the detection was less than 0.01. The threshold was evaluated based on the distribution of histograms of manually verified true and false detections. A trained analyst verified the detections as true or false.These data were recorded at SanctSound Site CI01_03 between August 14, 2019 and October 08, 2019. These data are available to the public for a wide variety of uses including scientific research and analysis.

NOAA-Navy Sanctuary Soundscapes Monitoring Project (SanctSound) Office of National Marine Sanctuaries sponsor U.S. Navy sponsor https://sanctuaries.noaa.gov/science/monitoring/sound/ Sound Monitoring NOAA and the U.S. Navy are working to better understand underwater sound within the U.S. National Marine Sanctuary System. From 2018 to 2021, 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 measurements will 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 research, including efforts by NOAA's Office of National Marine Sanctuaries This dataset represents the derived products from the raw acoustic data that are archived at NOAA National Centers for Environmental Information. information largerWorkCitation project eng; USA biota oceans Site CI01_03 -120.081 -120.081 34.04383 34.04383 2019-08-14T00:00:00Z 2019-10-08T09:00:00Z Passive acoustic data physicalMeasurement timestamp string Time in ISO 8601 date format presence double Presence of bocaccio calls (0 = not present; 1 = present) 1 0 presence double Bocaccio calls were detected automatically using Triton's Fish Detector.

Data quality was assessed through visual analysis and examination of acoustic levels over time across all frequencies. Bocaccio calls were detected automatically using the Fish Detector in Triton version 1.93 (Scripps Whale Acoustics Lab, San Diego, CA). Recordings were decimated to a sample rate of 2,000 Hz before running through the detector. The fish detector first filtered the time series between 100 and 950 Hz (10th order Butterworth filter). Then, it computed cross-correlation between the envelope of a filtered example call (3 s, Hann windowed) and 75s of the envelope of the filtered time series (i.e., Hilbert transform low pass filter). To enhance peaks in the signal, the cross correlation was squared. To account for detecting signals within background noise, we used a floating threshold of the median cross correlation value over the current 75 s of data, with a threshold offset of 2e-9 above the median. Detections were evaluated if they reached above this threshold. Consecutive calls were required to have a minimum time gap of 0.5 s to be detected separately. RMS received level was computed over the potential detection period and a time series of the length of the bocaccio call template before and after the detection. Detections were considered false and discarded if the signal-to-noise ratio between the detection period and the timeseries before and after the detection was less than 0.01. The threshold was evaluated based on the distribution of histograms of manually verified true and false detections. After running the detector, a trained analyst verified the detections as true or false.
