The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL abstract String 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 CI02_01 between October 31, 2018 and January 13, 2019.

attribute NC_GLOBAL comment String 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.

attribute NC_GLOBAL summary String 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.
