deployed on platforms ranging from autonomous underwa- ter vehicles to the animals themselves. Storage capacity and progress in battery technology now support the remote recording of acoustic data with wide bandwidths over the duration of a year and in multiple element arrays. When I entered the field almost 15 years ago the Holy Grail of pas-
sive acoustics was obtaining reliable density estimates from animal recordings, and the Holy Grail of active acoustics was the reliable automated classification of targets down to the species level. Based on the amazing research that has focused on the remote sensing of animals over the past few years, the Holy Grail may be in sight.
