    • Inverted echo sounder measurements collected in the Japan/East Sea, from 1999-06-08 to 2001-07-25, under the sponsorship of the Office of Naval Research (NCEI Accession 0002331)

    Metadata Updated: February 1, 2026

    Observations were conducted from June 1999 to July 2001 to study the 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). 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 Small gaps in the current measurements have been replaced by fitted-spline interpolated values.
