동해 울릉분지의 E-RAP(EAST-I Real-time Automatic Profiler)의 예비 관측 결과

Abstract

E-RAP (EAST-I Real-time Automatic Profiler), which was newly developed by the CREAMS/PICES EAST-1 (East Asian Seas Time-series I) program, had been deployed at the Super-Station of EAST-1 (37°00′ N, 131°00′E) located at the center of the Ulleung Basin of the East/Japan Sea since May 2010 until September 2010. Vertical profiles of temperature, salinity, dissolved oxygen, and fluorescence from the near surface (around 20 m) to the depth of 350 m had been collected once a day (May, 17 - June, 10) or twice a day (June, 10 - September, 1). The profiles were sent to the surface buoy in real-time by inductive modem through the deployment wire, then the buoy sent the data to the main shore workstation by a wireless telecommunication system (CDMA). The E-RAP data demonstrate clearly the Ulleung Warm Eddy movement. The E-RAP time-series are compared with nearby data obtained by other methods.
