Assessing the Deepwater Horizon oil spill impact on marine mammal population through acoustics: endangered sperm whales.
Azmy S. Ackleh,George E. Ioup,Juliette W. Ioup,Baoling Ma,Joal J. Newcomb,Nabendu Pal,Natalia A. Sidorovskaia,Christopher O. Tiemann +7 more
TL;DR: The first attempt to use multi-year passive acoustic data to study the impact of the Deepwater Horizon oil spill on the population of endangered sperm whales is reported, with a comparison of the 2007 and the 2010 recordings shows a decrease in acoustic activity and abundance of sperm whales at the 9-mile site by a factor of 2, whereas acoustic activity

TL;DR: Experimental and modeled data show good agreement in absolute pressure amplitudes and frequency interference patterns for frequencies up to 1000 Hz, which is important for investigating the potential impact on marine mammals and fish and predicting the exposure levels for newly planned seismic surveys in other geographic areas.

TL;DR: The Littoral Acoustic Demonstration Center (LADC) consisting of the University of Southern Mississippi (USM), UNO, and the Naval Research Laboratory at Stennis Space Center (NRL-SSC), with guidance and technical assistance from the Naval Oceanographic Office (NAVOCEANO), was formed to do ambient noise and marine mammal acoustic measurement and analysis.
