In order to study the time variability of Kuroshio transport and structure in the East China Sea (ECS), two lines of inverted echo sounders (IES) extending across the axis of the Kuroshio from the continental shelf to the Ryukyu Island chain were deployed for nearly two years. This part of the report describes the data recorded by these instruments and its preliminary processing. During the deployment crmse, XCTD casts were taken at each IES site; these data are also reported along with ship ADCP data taken during the IES deployment cruise. In addition, the technique used to generate GEM fields from historical hydrographic data in the ECS is explained. These GEM fields will be used to infer the dynamics of the region from the IES acoustic-travel-time (tau) records. Two bottom-mounted Acoustic Doppler Current Profiler (ADCP) moorings were deployed in the East China Sea (ECS) for 13 months to observe the part of the Kuroshio flowing over the outer continental shelf of the ECS. The main objectives of this study are to quantify the entire Kuroshio transport and to investigate the dynamics of its temporal variability using the ADCP data together with CPIES (current-and-pressure-sensor- equipped inverted echo sounder) data simultaneously obtained in the Okinawa Trough. This report describes the data recorded by the ADCPs and the preliminary processing. During the 4 ADCP mooring cruises, CTD casts were conducted along the CPIES-ADCP mooring line and these data are also reported.
