Abstract

The dataset contains sperm whale acoustic detections made during the MAPS winter cruise in Jan/Feb 2019 (NMFS permit 14809). Each datapoint represents an acoustic detection of an individual sperm whale.

Purpose

The MAPS (Marine Mammal Passive Acoustics and Spatial Ecology) cruises form part of a BOEM project to describe the distribution and behaviour of deep-diving cetaceans in the offshore waters of North Carolina (NMFS permit 14809). MAPS is a cooperative agreement between the Bureau of Ocean Energy Management and the University of North Carolina Wilmington in partnership with Duke University.
