These data sets include a compilation of small vessel based studies of bottlenose dolphins that reside within Mississippi Sound and nearshore coastal waters. The data consist primarily of photo-identification studies that use natural markings on animal dorsal fins to identify individuals over time. Surveys consist of line transects aboard small boats with concentrated effort to collect photographs of individuals. These photographs are reviewed to identify and catalog individual animals. In addition, several targeted studies have been conducted within this program to collect tissue biopsy samples for genetic and contaminant analyses. These data are used to examine demographic structure and population dynamics of the Mississippi Sound stock of bottlenose dolphins.

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 GR03_03 between October 17, 2019 and December 02, 2019.
