String abstract "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_02 between May 02, 2019 and September 09, 2019.";

String comment
"Data quality: A 20 Hz high pass filter is integrated into the instrument; thus, data below 20 Hz is reduced in ampitude and uncalibrated. The first 4 hour file was missing after turning on the instrument; thus the delay in data after deployment. Gap in data from 2019-07-06 16:00:41 UTC to 2019-07-06 16:05:54 UTC. Weird noise after card switch was removed from 2019-07-06 16:05:54 - 16:05:57 (3 sec extra removed). The fixed hydrophone mooring was moved after an interaction with something to a different habitat on June 13th, 2019. The fixed hydrophone mooring was impacted by Hurricane Dorian on September 4th, 2019, where the instrument was further moved. Hydrophone was found about 30 ft from original site at N 31 22.051, W -80 53.694. Reductions in sound levels (received levels) in frequencies above 1 kHz were observed after 21:20:00 13-June-2019 and were further observed after 15:47:00 4-September-2019. Levels may differ from what would be expected if the hydrophone was not moved or impacted by the two hurricanes.\r

"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

String summary "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.";

Data Access Protocol (DAP) and its
projection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst),
followed by [(start):stride:(stop)]
(or a shorter variation of that) for each of the variable's dimensions
(for example, [time][latitude][longitude]).
