NOAA-Navy Sanctuary Soundscape Monitoring Project, Pinniped Sound Production, Channel Islands, SanctSound_CI02_01_pinnipeds

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 pinniped sound production. Pinniped calls were detected by analysts and logged using Triton's Logger Remora. Calls were grouped into encounters, with encounters more than 30 min apart being logged as separate encounters. The following settings were used for manual scanning of long-term spectral averages: bandwidth 0-2000 Hz; 1 hour duration, FFT length 1000, 90% overlap.These data were recorded at SanctSound Site CI02_01 between October 31, 2018 and January 13, 2019.
acknowledgement=This project received funding from the U.S. Navy.

comment=Data quality: Recorded received level gradually decreases after 2018-11-30 for the frequencies below 200 Hz. This drift is caused by changes in the hydrophone sensitivity.

美国国家海洋和大气管理局（NOAA）与美国海军合作，旨在更深入地理解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合作，研究七个国家海洋保护区和一个海洋国家纪念地内的声音，包括夏威夷群岛以及东西海岸海域。标准化的测量将评估海洋动物、物理过程（例如风和波浪）以及人类活动产生的声音。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。此项工作是对海军和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。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。
