Hydrographic Doppler Sonar System (HDSS) upgrade

The Hydrographic Doppler Sonar System (HDSS), is now 20 years old and is getting upgraded when R/V Revelle undergoes her midlife refit this summer and fall.  HDSS is a state-of-the-art system for measuring ocean currents.  We are substantially upgrading and improving the old system, with enhancements including greater power and real-time beam forming that corrects for the roll and pitch of the ship, improving precision by keeping the beams much more constant orientation.

Engineers Sara Goheen and Mike Goldin and Professor Rob Pinkel ultrasonically clean a cable from the old system in preparation for the installation this summer and fall.
