The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL abstract String This record represents red grouper sound production detected from raw passive acoustic data. For each one-minute segment of data, calibrated spectrograms were generated and manually viewed for red grouper calls. Sounds with low signal strength were verified aurally. The number of red grouper sounds detected were summed, yielding a count of red grouper sounds per minute at ten-minute increments. These data were recorded at SanctSound Site FK01_01 between December 18, 2018 and April 19, 2019.
attribute NC_GLOBAL acknowledgement String This project received funding from the U.S. Navy.

attribute NC_GLOBAL comment String Data quality: The fixed hydrophone mooring was turned over on December 20th, 2018 and was not returned upright until March 26th, 2019; during this time the hydrophone was in contact with the seafloor. Reductions in sound levels (received levels) in frequencies above 1 kHz were observed from 2018-12-20 20:00:00 until 2019-03-26 14:45:00. Levels may differ from what would be expected if the hydrophone was not moved or impacted by these two events.

attribute NC_GLOBAL history String All continuous data were subsampled to examine one minute of data every ten minutes (10% duty cyle). For each one-minute segment of data, calibrated spectrograms were generated in Matlab (FFT length = 16,384 points, Kaiser-Bessel window with beta = 7.85, FFT overlap of 75%) and viewed by an analyst. Sounds with low signal strength were verified aurally. The number of red grouper sounds detectable after manual examination of each one-minute spectrogram were summed, yielding a count of red grouper sounds per minute at ten-minute increments. Data were processed with Matlab 2017a

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.
