Advanced Coherent Technologies, LLC (ACT) is using a multi-spectral, multi-channel imaging system to
detect and monitor marine mammals. The system, designed with US Navy funding, is intended to monitor mammals on
US Navy submarine training ranges prior to and during Navy active acoustic training activities. ACT has conducted
system tests and data collection activities at the St. Lawrence Seaway (Quebec, Canada), at Ma'alaea Bay (Maui,
Hawaii), and from the Coronado Bay Bridge (San Diego, California). A description of the imaging system and the
results of the data collections are discussed and presented.
