Dolphin Sound Production Recorded at SanctSound Site SB01_01

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). Frequency ranges used varied by sanctuary to encompass the frequency ranges of local populations. A frequency range of 1.5-22 kHz was selected for Stellwagen Bank National Marine Sanctuary (SBNMS) to encompass the frequency ranges of both pilot whales and white-sided dolphins. A frequency range of 4-18 kHz was selected for Gray's Reef National Marine Sanctuary (GRNMS) and Florida Keys National Marine Sanctuary (FKNMS) to encompass the frequency range of bottlenose dolphins and Atlantic spotted dolphins. In SBNMS, hours with detections less than 77 were automatically assigned as 0 presence and hours with detections greater than 565 were automatically assigned as 1 presence based on results from a Generalized Linear Model applied to a subsample of data from SB01. All FKNMS and GRNMS detected hours were reviewed. Presence in an hour was defined as 1+ detected whistles (or part of whistle) so long as it was not a solitary tone. 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 SB01_01 between November 12, 2018 and January 28, 2019.
