Fish chorusing patterns in California (USA) National Marine Sanctuaries

This dataset contains fish chorusing event logs used in the study \"Fish chorusing patterns in California National Marine Sanctuaries\", published in Marine Ecology Progress Series (Kim et al. 2025). The logs include the start and end times of fish chorusing events detected across nine passive acoustic monitoring sites located in the Monterey Bay, Channel Islands, and Chumash Heritage National Marine Sanctuaries from 2018–2022. Chorus detections are categorized by species, including bocaccio rockfish (Sebastes paucispinis), plainfin midshipman (Porichthys notatus), white seabass (Atractoscion nobilis), and two unidentified fish types. , Through the Sanctuary Soundscape Monitoring project, we collected passive acoustic data across 9 sites, each recording for ~2 years for a cumulative 18.3 recording-years. We manually analyzed acoustic data (logging start and end times of each chorus type) for fish chorusing in Monterey Bay, Chumash Heritage, and Channel Islands National Marine Sanctuaries.
We collected passive acoustic data using SoundTraps (Soundtrap ST500 and Soundtrap ST600, Ocean Instruments, NZ) at three sites in MBNMS, one in originally proposed CHNMS, and five sites in CINMS over multiple deployments from 2018-2023. Sites were named after location, with Channel Islands abbreviated to “CI,” Chumash Heritage to “CH,” and Monterey Bay to “MB,” and numbers allowing for further differentiation between recording sites, and then further number indicating deployment numbers.  Raw WAV files underwent compression for long-term spectral averages (LTSAs), employing 1000-point fast Fourier transforms (FFTs), Hanning wind..., , # Fish Chorus Logs in California National Marine Sanctuaries

This dataset contains all fish chorus logs manually detected from passive acoustic data collected in Monterey Bay, Channel Islands, and proposed Chumash Heritage National Marine Sanctuaries. All manual fish chorus logs that were used for data analysis are available here.

## Data and File Structure

Data is structured as individual xls files, organized by site and deployment with the format \"Siteabbreviation_site number_deployment number\", ex. \"CI01_02_03\" is Channel Islands, site 2, deployment 3. Within each spreadsheet, you will find a Detection tab which includes start and end date-times of fish chorus detections in UTC (in MM/DD/YYYY HH:MM:SS.s format), as well as fish chorus names under \"comments.\" Under the MetaData tab you will find start and end effort times, indicating times instruments were in the water during the deployment.
