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 fin whale calls detection from raw passive acoustic data. Daily presence of fin whale 20 Hz pulses was detected by analysts and logged using Triton's Logger remora. When hourly background noise levels in the 31.5 Hz octave band exceeded 95 dB, the noise was considered too high to reliably detect calls. These periods were marked as no effort, leading to ratio of effort per day, with 0 being no effort and 1 being 24 hours effort. The settings of the Long-Term Spectral Average (LTSA) used to scan for calls were: window length = 1 h, frequency range = 0-250 Hz, Brightness = 15-20 dB, Contrast = 250%.These data were recorded at SanctSound Site CI03_02 between October 15, 2019 and February 19, 2020.

美国国家海洋与大气管理局（NOAA）与美国海军合作，致力于深入探究美国国家海洋保护区系统内的水下声音。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音进行研究，涉及夏威夷群岛以及东、西海岸海域。通过标准化测量，评估海洋生物、物理过程（如风浪）及人类活动产生的声音。这些信息的综合分析将有助于NOAA和海军测量保护区内的声音水平和基线声学条件。此项目是对海军与NOAA持续研究工作的延续，包括NOAA国家海洋保护区办公室的努力。本数据集代表了存储于NOAA国家环境信息中心的原始声学数据的派生产品。
