Abstract:
The primary objective of this research is to Develop a predictive model for population health of Blainville s beaked whale Mesoplodon densirostris, Md in the Tongue Of The Ocean TOTO, Bahamas, using data from passive acoustic monitoring collected around and during active sonar operations. MFA sonar operations occur repeatedly on Navy ranges that are known to contain populations of Blainville s Mesoplodon densirostris, Md and Cuvier s Ziphius cavirostris, Zc beaked whales. Strandings of these species have been associated with the use of Navy sonar 1, 2. A population of Md is known to use the Atlantic Undersea Test and Evaluation Center AUTEC range in the Tongue Of The Ocean TOTO, Bahamas 3, and a population of Zc has been documented on the Southern California Offshore Range SCORE off San Clemente Island in California 4. Developing a methodology for monitoring the long-term health of populations such as these, that are repeatedly exposed to sonar, is important for the continued operational integrity of these ranges.
