Count Component Title Abstract
1 Vessel Detection Events Recorded at SanctSound Site CI02_02 This record represents the individual vessel events detected from raw passive acoustic data. Events are identified from the long-term spectral average (LTSAs) created for each site with a 5 s, 48 kHz resolution. The LTSA is analyzed in blocks where the calibrated power spectral density estimates are averaged in user-defined low, medium and high frequency bands. These data were recorded at SanctSound Site CI02_02 between March 25, 2019 and July 23, 2019.

          1 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

          1 Vessel events (individual events) were detected using Triton's Ship-Detector Remora. An LTSA is created for each site with a 5 s, 48 kHz resolution; events are identified from these LTSAs. Individual site settings are tested using the Interactive Detector and most conservative settings are run using the Batch Detector. The LTSA is analyzed in blocks of data (windows), where the calibrated sound pressure spectral density (PSD) estimates are averaged in three frequency bands; low, medium and high (defined by user). Start and end times of the events are detected and stored if the three averaged PSDs meet three conditions (all values set by user): 1. Amplitude is above a user-defined, time-dependent amplitude threshold computed using a histogram method of the averaged PSDs; 2. The event duration is above a user-defined time in the three bands. The duration in the higher band must be shorter that the medium band, or the event duration above the threshold in the lower and medium band must be longer than the user specified time, and the duration in the medium band must be shorter than the lower band; 3. Events are distinguished from weather events when averaged received levels of the event in the lower band are above a user specified percentage of the background sound in the window. The window length and the overlapping time with the next consecutive window is defined by the user. Once Batch Detector is run, user reviews results and corrects labelled events to either Ambient (non-ship source) or Ship. Low Band=100-5,000 Hz, Medium Band=5,000-10,000 Hz, High Band=10,000?48,000 Hz, Close Passage Duration Threshold: 50 s, Distant Passage Duration Threshold: 150 s, Relative Threshold Level = 0.05%, Time Between Passages = 0.01 hr, Buffer Time (min): 5, Window Size (h): 2, Sliding Time Overlapping Windows (h) = 0.5.
          1 Data were processed with Triton - Soundscape Metrics Remora (Github commit '44f0f20'; Feb 9, 2020) and Matlab (2016b and newer; statistics toolbox).
