Dolphin Sound Production Recorded at SanctSound Site MB02_04

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-04-15T00:00:00.000+00:00
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 (v. 2.01.03, Gillespie et al. 2013). A frequency range of 4-20 kHz was selected to encompass the frequency range of common dolphins, Pacific white-sided dolphins, and bottlenose dolphins. 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. Only full hours of data were analyzed. These data were recorded at SanctSound Site MB02_04 between December 21, 2019 and March 22, 2020.
