동해 남서해역에서 ADCP 자료에 의한 후방산란 강도와 수온구조와의 비교
Comparison of the Temperature Profile with the Backscattering Strength by the ADCP Data in the Southwestern Part of the East Sea
초록
1993년 4월 동해 남서해역에 발생한 난수성 소용돌이의 수온구조와 ADCP (Acoustical Doppler Current Profiler)의 음향자료를 이용하여 계산된 후방산란 강도 구조의 상관관계를 연구하였다. 후방산란 강도 계산 결과, 난수성 소용돌이 중심부와 1
The relationship between temperature profile and backscattering strength(S/SUB y/) computed by the ADCP data is studied in warm eddy of the southwestern parts of the East Sea of Korea in April, 1993. The result shows that S/SUB y/ with depth in N-S direction shows a symmetric shape that is almost the same as the warm eddy. But the profile of S/SUB y/ with depth in N-S direction shows a symmetric shape that is almost the same as the warm eddy. But the profile of S/SUB y/ in E-W direction shows asymmetric shape where the S/SUB y/ of the eastern parts is smaller than that of western parts. The asymmetric distribution may be due to the migration of a large number of scatterer(mainly zooplankton) carried by EKWC(East Korea Warm Current). Profile of the S/SUB y/ is similar to the temperature with depth in the ADCP data of CREAMS 93(Circulation Research of the East Asian Marginal Seas).
