The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL abstract String This record represents manual detection of humpback whale sounds. Humpback presence was determined by manually scanning long-term spectral averages (LTSAs) in the Triton MATLAB software package. Acoustic files were decimated to a sample rate of 4 kHz before generating 5 s, 1 Hz LTSAs. The LTSA was scanned by a trained analyst in hourly bins for visual evidence of song and non-song humpback vocalizations. Detections were aurally confirmed. These data were recorded at SanctSound Site CI01_07 between March 05, 2021 and July 01, 2021.
attribute NC_GLOBAL acknowledgement String This project received funding from the U.S. Navy.

attribute NC_GLOBAL history String Humpback presence was determined by manually scanning long-term spectral averages (LTSAs) in the Triton MATLAB software package. Acoustic files were decimated to a sample rate of 4 kHz before generating high-resolution LTSAs, averaged over 5 seconds in 1 Hz bins. The LTSA was scanned by a trained analyst in hourly bins for visual evidence of humpback vocalizations, including both song and non-song vocalizations. Detections were aurally confirmed to be humpbacks before logging a positive detection in the Triton Logger Remora. LTSA display settings: Window type = Hanning, NFFT = 4,000, Brightness = 30, Contrast = 100, Plot length = 1 hr, Plot frequency = 0-2,000 Hz. Window display settings: NFFT = 1,000, Overlap = 90%, Brightness = 30, Contrast = 100, Plot length = 60 seconds, Plot frequency = 0-2,000 Hz Data were processed with Triton - (1.93.20160524/Github version d81e5fa) and Matlab (2020b).

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.
