Pressure/temperature/salinity profiles collected in support of a study to investigate the shallow and deep current variability in the southwest Japan/East Sea. Previous 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) (NCEI Accession 0002331). Hourly measurements of vertical acoustic travel time, pressure, temperature and horizontal currents are provided. Additional processing has been done to provide data sets which can easily be used together as a coherent array. The travel time records have been projected on to a common depth level, low-pass filtered, and subsampled to twice daily. The low-pass filtered, subsampled pressures have been adjusted to a common, deep geopotential surface. Small gaps in the current measurements have been replaced by fitted-spline interpolated values.
