Abstract

Mechanical current meters deployed within the upper part of the water column, in regions of high wave energy, may measure current velocities inaccurately. A modified Aanderaa meter was compared in the field with the standard Aanderaa meter, with a propeller-type NBA meter and with OSCR (Ocean Surface Current Radar) measurements. Comparison was also made with the standard Aanderaa in a wave-simulating flume. The modified meter showed reduced susceptibility to overreading in the presence of waves, particularly under conditions of low current velocities. Graphs are presented to allow prediction of wave effects on both the modified and standard Aanderaa meters.
