Current Population Survey: Basic Monthly
Data provided by United States Census Bureau
To provide estimates of employment, unemployment, and other characteristics of the general labor force, of the population as a whole, and of various subgroups of the population. Monthly labor force data for the country are used by the Bureau of Labor Statistics (BLS) to determine the distribution of funds under the Job Training Partnership Act. These data are collected through combined computer-assisted personal interviewing (CAPI) and computer-assisted telephone interviewing (CATI).

Sound Pressure Spectral Density at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
This record represents the sound pressure spectral density (PSD) levels derived from raw passive acoustic data. The hourly PSD levels were calculated as the median of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz from 10 Hz to 24,000 Hz over no less than 1,800 seconds in each hour and converted to decibels (dB re 1 µPa^2/Hz). These data were recorded at SanctSound Site SB01_01 between November 12, 2018 and January 28, 2019.

One-third Octave Band Sound Pressure Levels at 1 Hour Resolution Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
This record represents the one-third octave band sound pressure levels (TOLs) derived from raw passive acoustic data. TOLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over 33 one-third octave bands with the nominal center frequencies ranging from 13 to 20,000 Hz.

Atlantic Cod Sound Production Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
This record represents the Atlantic cod sound production detected from raw passive acoustic data. All acoustic data were processed using the automatic grunt detector and recogniser for Atlantic cod. This method uses a two-stage hypothesis testing algorithm that includes detecting and recognizing all grunt-like sounds. Detector output was manually verified, and false positives are removed. These data were recorded at SanctSound Site SB01_01 between November 12, 2018 and January 28, 2019.

Blue Whale Sound Production Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
This record represents blue whale sound production detected from raw passive acoustic data. The Low Frequency Detection and Classification System (LFDCS) call library for blue whales was built for the data sampled at 120 Hz, and created for A, B, and AB phrases. All detections with a Mahalanobis distance of 5.0 or less were manually screened. Daily presence for blue whales was confirmed if there were three song phrases visible, including at least one true detection. Only accepting detections when three or more phrases occurred ensured our confidence in blue whale song presence.

Dolphin Sound Production Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
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.

Fin Whale Sound Production Recorded at SanctSound Site SB01_01
Data provided by National Oceanic and Atmospheric Administration
This record represents fin whale sound production detected from raw passive acoustic data. The Low Frequency Detection and Classification System (LFDCS) call library for fin whale 20-Hz pulses was built for the data sampled at 120 Hz. All fin whale detections with a Mahalanobis distance of 3.0 or less were manually verified for true detections. A logistic regression was applied to these results to facilitate reducing the size of the dataset that ultimately needed to be manually verified for confident species detection.
