Ocean Scientific International Limited (OSIL) has designed a system for testing deployments by surrounding SonTek’s Acoustic Doppler Current Profiler (ADCP) with its own deployment frame. The ADCP is a 3-axis water current profiler with an intended range of 180 m that uses transducers and electronics designed to reduce side-lobe interference problems. The frame also contains a double failsafe recovery system using two Sonardyne acoustic releases per frame. The first of these systems is scheduled for deployment in the Middle East during the summer of 2009.
