Modeling the performance of the PT Sur hydrophone array in localizing blue whales

The acoustic activity of the blue whale is widely documented yet poorly understood. Hypotheses for its vocalizations range from communication, bathymetric echolocation and echolocation of zooplankton masses. Although extensive documentation of frequency structure and duration exists, a long term mon...

Description
Summary:The acoustic activity of the blue whale is widely documented yet poorly understood. Hypotheses for its vocalizations range from communication, bathymetric echolocation and echolocation of zooplankton masses. Although extensive documentation of frequency structure and duration exists, a long term monitoring of where and when the vocalizations are being made must be accomplished to test the validity of these theories. The Naval Postgraduate School (NPS) Ocean Acoustic Observatory (OAO), which operates a former Sound Surveillance System (SOSUS) at Pt Sur, presents itself as a potentially valuable tool in the detection and localization of Pacific blue whales Approved for public release; distribution is unlimited.
