Abstract:

DRDC Atlantic has an ongoing research program that requires the transmission of acoustic energy in an undersea environment. Though the transmissions are generally at a relatively low level, every effort must be made to mitigate the potential for impact on marine life. Future impact mitigation measures may include the development detectionclassification capabilities for marine mammal vocalizations. The ocean environment tends to be noisy, so that the detection of noise itself is inadequate for alerting researchers of the presence of marine mammals. The noise must be classified as to its origin. e.g. has it been generated by a marine mammal. The objective of this study was to further DRDCs understanding of whale vocalizations with the aim of developing automatic acoustic whale detectors and identifiers.
