Blue Whale Sound Production Recorded at SanctSound Site MB02_01
This record represents blue whale sound production detected from raw passive acoustic data. Blue whale B calls were detected using Triton's Blue Whale B Call Detector Remora. The detector uses spectrogram correlation (Mellinger and Clark, 2000) to detect calls with a kernel (an average B call) that is generated from a subset of calls. The kernel was calculated from 30 excellent quality B calls that were at least 24 hours apart. A kernel was generated per sanctuary for every six months of data. Kernel quality and optimal threshold settings were tested by running the detector through a subsample of data in which 200-400 calls were manually detected. The comparison between manual and automatic detections was used to calculate precision and recall of the detector, in percentages. Settings were considered optimal when precision and recall were both 85% or higher. These settings were then used to run the detector through the entire dataset for that deployment. Wav files were first decimated to 2 kHz sampling rate. Detector results were manually verified during time periods in which few detections were expected.These data were recorded at SanctSound Site MB02_01 between November 15, 2018 and April 07, 2019.

"description": "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.",
