Observations were conducted from June-1999 to July-2001 to study shallow and deep
current variability in the southwest Japan/East sea. Data were collected during the
field experiment with a two-dimensional array of pressure-gauge equipped inverted
echo sounders (PIES) and deep recording current meters (RCM). This report documents the current meter data, which were collected with an array of 12 moorings
that was in place for the two-year period. Instrument preparation, calibration and
deployment/ recovery procedures, plus data processing procedures are discussed. Basic statistics of the cleaned hourly data and forty-hour low passed filtered time series are presented, followed by time series of the currents and temperatures measured by the Aanderaa current meters. The final section shows plots of mean current vectors and variance ellipses as well as histograms of current speed and direction.
