This record represents dolphin whistle and moan sound production detected from raw passive acoustic data. All acoustic data were processed through Pamguard's Whistle and Moan Detector. For Hawaiin Islands Humpback Whale National Marine Sanctuary and Papahānaumokuākea Marine National Monument recorders, a frequency range of 8-20 kHz was selected to encompass the frequency ranges bottlenose dolphins, pan-tropical spotted dolphins, and spinner dolphins. Hours with no detections were assigned as 0 presence. Hours with dolphin were assigned as 1. Presence in an hour was defined as 1+ detected whistles (or part of whistle) so long as it was not a solitary tone. Each detection was not annotated but rather the hour as a whole was marked with a 0 or 1.These data were recorded at SanctSound Site HI04_02 between December 01, 2019 and May 11, 2020.
