Measuring currents in demanding environments with a Seaguard® RCM

Abstract

As a result of joint efforts spearheaded by leading oceanographic institutions, several Seaguard® current meters have participated in a number of inter comparison studies in different parts of the world, covering areas from coastal shallow waters to deep ocean basins. From all these deployments, datasets of high quality have been obtained, despite the environmental conditions being sometimes far from ideal. The ability of the SEAGUARD® current meters (Aanderaa Data Instruments) using ZPulse™ technology to collect high quality data under difficult dynamic conditions (high tilts and mooring line vibration/rotations) as well as different backscatter levels will be discussed and illustrated with data from these deployments.
