NOAA-Navy Sanctuary Soundscape Monitoring Project, Octave Sound Pressure Levels, Florida Keys, SanctSound_FK01_07_OL_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 octave band sound pressure levels (OLs) derived from raw passive acoustic data. OLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over 10 octave bands with the center frequencies ranging from 31.5 to 16,000 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_07 between March 17, 2021 and April 25, 2021.

history=Octave band sound pressure levels (OLs) 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 each of 10 octave bands (ISO266-1997) with the center frequencies ranging from 31.5 to 16,000 Hz. The resulting OLs with 1 second resolution were then used to calculate hourly OLs as a median over no less than 1,800 1-second values for that hour. The OLs 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).

{'abstract': '国家海洋和大气管理局（NOAA）与美国海军携手致力于深入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及一个海洋国家纪念地的声音，包括夏威夷岛以及东西海岸附近水域。标准化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。汇总这些信息将有助于NOAA和海军评估保护区内的声音水平和声学基线条件。此项研究是海军和NOAA持续研究工作的延续，包括国家海洋保护区办公室的努力。本数据集代表了存储在国家海洋和大气管理局国家环境信息中心的原声数据派生产品。', 'acknowledgement': '本项目获得美国海军的资助。', 'cdm_data_type': '时间序列数据', 'citation': '引用格式：NOAA国家海洋保护区办公室和美国海军。2021。在SanctSound站点FK01_07记录的1赫兹和1小时分辨率的倍频带声压级，SanctSound数据产品。NOAA国家环境信息中心。访问日期。[DOI：https://doi.org/http://doi.org/10.25921/te54-ta08]', 'comment': '数据质量：部署期间记录了高质量数据。', 'contributor_name': 'Simone Baumann-Pickering，斯克里普斯海洋研究所；Leila Hatch，NOAA Stellwagen Bank国家海洋保护区；John Joseph，美国海军研究生院；Anke Kuegler，夏威夷大学海洋生物学研究所；Marc Lammers，NOAA夏威夷群岛座头鲸国家海洋保护区；Tetyana Margolina，美国海军研究生院；Karlina Merkens，NOAA太平洋岛屿渔业科学中心；Lindsey Peavey Reeves，NOAA海峡群岛国家海洋保护区；Timothy Rowell，NOAA东北渔业科学中心；Jenni Stanley，伍兹霍尔海洋研究所；Alison Stimpert，莫斯兰丁海洋实验室；Sofie Van Parijs，NOAA东北渔业科学中心；Eden Zang，NOAA夏威夷群岛座头鲸国家海洋保护区', 'contributor_role': '项目负责人', 'Conventions': 'COARDS, CF-1.6, ACDD-1.3', 'defaultGraphQuery': 'sound_pressure_levels[][]&.draw=surface&.vars=time|frequency|sound_pressure_levels&.yRange=||true|Log', 'featureType': '时间序列数据', 'geospatial_bounds': '点（24.43313 -81.93068）', 'history': "倍频带声压级（OLs）以微帕斯卡平方（µPa^2）为单位，通过将均方声压（µPa^2）的声压谱密度（PSD）估计值与每个10个倍频带（ISO266-1997）的1赫兹（Hz）/1秒分辨率进行积分计算得出。然后，具有1秒分辨率的所得OLs被用于计算每小时OLs，作为该小时至少1,800个1秒值的平均值。每小时OLs转换为分贝（dB re 1 µPa）。数据通过Triton - 声景度量Remora（Github提交'44f0f20'；2020年2月9日）和Matlab（2016b及更新版；统计工具箱）进行处理。", 'id': 'http://doi.org/10.25921/te54-ta08', 'infoUrl': 'https://ncei.noaa.gov', 'institution': 'NOAA', 'instrument': 'SoundTrap ST501', 'keywords_vocabulary': 'GCMD科学关键词', 'naming_authority': 'NOAA-Navy', 'project': 'NOAA-Navy sanctuary soundscape monitoring project', 'sourceUrl': '(本地文件)', 'standard_name_vocabulary': 'CF标准名称表v55', 'time_coverage_end': '2021-04-25T17:00:00Z', 'time_coverage_start': '2021-03-17T12:00:00Z'}
