NOAA-Navy Sanctuary Soundscape Monitoring Project, Mid Frequency Active Sonar, Channel Islands, SanctSound_CI05_03_sonar

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 encounters of active sonar. Encounters of low and mid-frequency active sonar were logged manually from Long-term Spectral Averages using the Logger remora in Triton and user-defined settings. All detected signals with the same characteristics detected within 1 hour of each other were considered one encounter.These data were recorded at SanctSound Site CI05_03 between August 14, 2019 and October 11, 2019.
acknowledgement=This project received funding from the U.S. Navy.

history=Encounters of active sonar were logged manually from Long-term Spectral Averages (LTSA), using the Logger remora in Triton (Scripps Whale Acoustics Lab, La Jolla, USA), with the following settings: Window length = 1 h, Frequency range = 0-6000 Hz, Brightness = 40 dB, Contrast = 100%. All detected signals with the same characteristics detected within 1 hour of each other were considered one encounter. Data were processed with Triton - (1.93.20160524/Github version d81e5fa) and Matlab (2016b and newer; statistics toolbox).

美国国家海洋和大气管理局（NOAA）与美国海军合作，旨在更深入地探究美国国家海洋保护区系统内的水下声学环境。自2018年至2021年，这些机构将与众多科学合作伙伴共同研究七个国家海洋保护区及一个海洋国家纪念区的声学状况，涉及夏威夷岛以及美国东西海岸附近水域。通过对海洋动物、物理过程（例如风浪）以及人类活动产生的声音进行标准化测量，收集到的信息将有助于NOAA和海军评估保护区内的声音水平和声学基础条件。此项研究是NOAA和海军持续进行的科研工作的延续，包括国家海洋保护区办公室的科研努力。该数据集代表了NOAA国家环境信息中心存档的原始声学数据派生产品。
