NAVAL FACILITIES ENGINEERING COMMAND PORT HUENEME CA/MRADS PEARL HARBOR United States
Naval Facilities Engineering and Expeditionary Warfare Center NAVFAC EXWC was tasked with conducting a thorough investigation and analysis of a passive acoustic data set recorded off Oahu, Hawaii from 2010-2013. This effort is the second analysis of the data set, involving many more manhours of labor-intensive manual analysis by researchers after the previous effort reported in SSR-NAVFAC-EXWC-EV-1501 JUNE 2014 to develop an automatic detection computer algorithm proved unsuccessful due to the high noise in the shallow water environment. This report is a continuation of that effort. This research was funded by Pacific Fleet and included support from NAVFAC EXWCs Marine Resource Assessment Diving Services MRADS and the Hawaii Institute of Marine Biologys Marine Mammal Research Program. The specifics of the study are enclosed in this report as Appendices formatted for publication in the Journal of the Acoustic Society of America JASA, a spreadsheet of raw data for 800 odontocete whistle detections, and a summary of additional efforts at programming an automated detection algorithm.
