North Atlantic Right Whale Sound Production Recorded at SanctSound Site SB02_08

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-04-15T00:00:00.000+00:00
This record represents North Atlantic right whale (NARW) sound production detected from raw passive acoustic data. The Low Frequency Detection and Classification System (LFDCS) call library for right whale low-frequency modulated upsweep (upcall) was used for the data. All NARW upcall detections with a Mahalanobis distance less than or equal to 3.0 were manually screened due to variability in NARW upcalls and overlap with other species’ vocalizations, such as upsweeps produced by humpback whales. A given day was marked as having NARWs present if three or more true upcall detections. These data were recorded at SanctSound Site SB02_08 between January 31, 2020 and April 07, 2020.
