Acoustic summary data from hydrophone deployments at coral reefs in St. John, U.S. Virgin Islands in 2016 and 2017

Abstract:

A passive acoustic recorder was deployed at various coral reefs in St. John, U.S. Virgin Islands between 2016-03-28 and 2017-07-11. This dataset contains average sound pressure level, low frequency sound pressure level (50 - 1500 Hz), high frequency sound pressure level (2 kHz - 20 kHz) and peak frequency of files at each site, sorted by files with and without boat noise.

Methods & Sampling

Methodology:

One SoundTrap ST300 passive acoustic recorder (Ocean Instruments NZ, Inc.) was deployed at each coral reef over the course of one year. Hydrophones were attached to rebar stakes 0.75 meters from the seafloor with the omnidirectional hydrophone facing the sea surface. One-minute files were recorded every ten minutes. See Dinh et al. 2018 for more details.

RMS sound pressure level in two separate bands, overall sound pressure level, and peak frequency were calculated for each recording. Files were sorted by site and presence of boat noise. For each group of recordings, the median sound pressure level, high frequency sound pressure level, low frequency sound pressure level, and peak frequency were calculated.

Problem report:
Hydrophones were offloaded and recharged between deployments. Gaps exist due to hydrophone malfunction. See Dinh et al. for more details.
