Abstract:

Observations were conducted from June 1999 to July 2001 to study the shallow and deep current variability in the southwest JapanEast 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. The collection, processing and calibration of the PIES are documented in this report. Descriptions of the processes used to identify and remove jumps offsets in the pressure and travel time records, that resulted when the instruments were jostled or moved by deep crab-fishing activities in the JapanEast Sea, are given. Time series plots of travel time, bottom pressure, and temperature are presented for the 24 recovered instruments. Basic statistics of the hourly data are tabulated.
