Description
Data on sperm whales recorded at the Atlantic Undersea Test and Evaluation Center in the Tongue of the Ocean, Bahamas in August/September 2007. Complete dataset. more

This archive contains data on sperm whales (Physeter macrocephalus) recorded at the Atlantic Undersea Test and Evaluation Center (AUTEC) in the Tongue of the Ocean, Bahamas in August/September 2007. Data are provided showing when sperm whales were detected on the range during the time period, details about the availability of the acoustic data used in the analysis and finally, the number and size of sperm whale groups localized. This data represents sperm whale detections on the range during the complete study period. 44 days were monitored using an automatic detector for the presence of sperm whales: 12 Aug 2007 (julian day 224) - 24 Sept 2007 (julian day 267). This file documents when sperm whales were detected by the AUTEC range (the detections were verified by an observer). This dataset used multiple hydrophones at AUTEC to detect sperm whale clicks. Click trains from individual whales were identified, enabling the number of diving whales to be estimated. Assuming that all diving sperm whale groups at a given time are detected by AUTEC, then density of diving sperm whales can be estimated. The related dataset of number of whale groups localized can be found at http://seamap.env.duke.edu/dataset/680.
