NOAA-Navy Sanctuary Soundscape Monitoring Project, Broadband Sound Pressure Levels, Florida Keys, SanctSound_FK01_04_BB_1h

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.
abstract=This record represents the broadband (BB) sound pressure levels (SPLs) derived from raw passive acoustic data. BB SPLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over the frequency band of 20 to 24,000 Hz. The result is then calculated per hour as a median over no less than 1,800 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound Site FK01_04 between February 20, 2020 and June 12, 2020.

history=Broadband (BB) sound pressure levels (SPLs) in units of µPa^2 were calculated by integration of sound pressure spectral density (PSD) estimates of the mean-square pressure (µPa^2) with a 1 Hertz (Hz)/1 second resolution over the frequency band of 20 to 24,000 Hz. The resulting BB SPLs with the 1 second resolution were then used to calculate BB SPLs per hour as a median over no less than 1,800 1-second values for that hour. The BB SPLs per hour were converted to decibels (dB re 1 µPa). Data were processed with Triton - Soundscape Metrics Remora (Github commit '44f0f20'; Feb 9, 2020) and Matlab (2016b and newer; statistics toolbox).

国家海洋与大气管理局（NOAA）与美国海军合作，旨在深化对美国国家海洋保护区系统内水下声学的研究。自2018年至2021年，这些机构将与众多科学合作伙伴携手，对七个国家海洋保护区及一个海洋国家纪念地内的声学进行探究，涉及夏威夷群岛及美国东西海岸的海域。通过标准化测量，评估海洋动物、物理过程（如风浪）以及人类活动产生的声音。汇总这些信息，将有助于NOAA和海军测量保护区内的声音水平和声学基线条件。此项研究是海军和NOAA持续研究的延续，包括国家海洋保护区办公室的努力。该数据集代表了存档于NOAA国家环境信息中心的原始声学数据的衍生产品。
