Shore-cabled PAM

The shore-cabled passive acoustic monitoring system provides a long-term solution for deployment close to shore.

seabed-hydrophone-frame-cadA seabed-mounted hydrophone cabled to the receiver station enables continuous monitoring of coastal waters where there are no ongoing marine operations. This makes it ideally suited to simultaneous acoustic and visual monitoring of marine mammals.
