DCLDE 2027 Acoustic Detections and Aerial Surveys of North Atlantic Right Whales in Cape Cod Bay, MA

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 09:47 PM | Dataset Last Updated: March 27, 2026 at 12:00 AM
This dataset is composed of automated detections of North Atlantic right whale upcalls from an acoustic survey conducted in Cape Cod Bay (CCB) from February 17th to June 12th, 2019. Additionally, over the course of the acoustic survey, the Center for Coastal Studies performed 21 aerial surveys over CCB, in which all observed right whales were photographed and individually identified. As the aerial surveys provided a conservative measure of right whale abundance in CCB, this dataset enables the evaluation of acoustic abundance estimates. Aerial survey data was collected under NOAA federal permit #19315-01. For more detail on the acoustic and aerial survey protocols, please reference the attached manuscript [Garcia & Tolkova et al, 2025].
