Mensinger 20250417 tabular digital data data.usgs.gov U.S. Geological Survey https://doi.org/10.5066/P96KZ3IC In this study, passive acoustic monitoring was conducted at Lock No. 19 near Keokuk, Iowa on the Upper Mississippi River between 20 June – 26 August 2019 to coincide with peak navigation use. Sound pressure levels were calculated from .wav files collected with passive SoundTrap hydrophones at six locations in the downstream lock approach. This data set consists of the location and calibration information for the six hydrophones. The data were used to understand the background sound levels in the lock approach to inform the installation and operation of an underwater acoustic deterrent system. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. These data were collected to understand the soundscape of the downstream lock approach area 20190620 20190828 ground condition Complete None planned Lock and Dam 19 -91.377479 -91.375990 40.392519 40.391486 ISO 19115 Topic Category biota None Passive acoustic monitoring vessel sound acoustic deterrents freshwater fishes navigational locks soundscape USGS Thesaurus fish USGS Metadata Identifier USGS:67ae357ed34e3f09c0e0f24b None Lock and Dam 19, Keokuk Iowa, Upper Mississippi River None.

Hydrophone information: All hydrophones had a flat 3 dB frequency response between 10 and 72,000 Hz and were calibrated prior to deployment using a G.R.A.S. Type 42AA pistonphone (G.R.A.S. Sound & Vibration, Denmark) projecting 250 Hz at 114 dB re 20 μPa. Hydrophone position was obtained using a Garmin Montana 680t GPS unit. 20200131 Rosalyn L.

The subsequent percentiles were determined over the frequency range (dB re. 1μPa@ 50–12000 Hz) for each hydrophone location. We followed the processing steps described in Merchant, N.D., Fristrup, K.M., Johnson, M.P., Tyack, P.L., Witt, M.J., Blondel, P., Parks, S.E., 2015. Measuring acoustic habitats. Methods in Ecology and Evolution 6, 257–265. The Merchant et al. 2015 corrigendum (https://doi.org/10.1111/2041-210X.13824) did not effect this data because we did not conduct a one-third octave band analysis. 20200131 Rosalyn L.
