Bottom pressure near the Ryukyu Island Chain with 21-day period
As a part of the Joint Kuroshio–Ryukyu Current System Study (JKRYCSS) between June 2015 and June 2017, two pressure-recording inverted echo sounders (PIESs) and five current and pressure-recording inverted echo sounders (CPIESs) deployed along a section transecting the Kuroshio and Ryukyu currents near Miyakojima Island, southwest of the Kerama Gap provided 2-year bottom pressure records which shows significant 21-day period variability.

Devices
PIES(pressure-recording inverted echo sounders) is an echo sounder that rests on the seafloor and records acoustic round-trip travel time, bottom pressure, and bottom temperature. CPIES(current and pressure-recording inverted echo sounders) is a PIES further equipped with a current meter ~50 m above the bottom.
