The Dataset's Variables and Attributes

Row Type	Variable Name	Attribute Name	Data Type	Value
attribute	NC_GLOBAL	abstract	String	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 SB02_02 between January 28, 2019 and April 02, 2019.

attribute	NC_GLOBAL	history	String	All acoustic data were processed through Pamguard's Whistle and Moan Detector (v. 2.01.03, Gillespie et al., 2013). For Stellwagen Bank National Marine Sanctuary (SBNMS) recorders, a frequency range of 1.5-22 kHz was selected to encompass the frequency ranges of both pilot whales and white-sided dolphins. For Gray's Reef National Marine Sanctuary (GRNMS) and Florida Keys National Marine Sanctuary (FKNMS) a frequency range of 4-18 kHz was selected 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 (GLM) conducted using a subsample of data from SB01 for an entire year (following methods in Davis et al. 2017). The GLM was inconclusive for FKNMS and GRNMS thus all 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. 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. Data were processed with Pamguide 2.01.03

attribute	NC_GLOBAL	summary	String	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.
