dc.description.abstract수중 초음파 (5, 10, 15 MHz)를 사용하여 적조 플랑크톤 Cochlodinium polykrikoides (식물 플랑크톤, 편모조류)의 후방산란 특성을 파악하기 위한 음향 실험을 실시하였다 적조 산란체의 적조주의보 (300 cells/a) 보다 적은 양의 개체 수 변화를 탐지하였고, 개체군 밀도와 후방 산란신호와의 상관관계를 시간영역에서와 주파수 영역에서 확인하였다. 또한, fluid-sphere model[1]을 이용한 이론적인 체적 산란강도를 계산하여 실측 체적 산란강도와 비교한 결과가 잘 일치하였다. Laboratory measurements were performed in a uni-algae medium Cochlodinium polykrikoides (Phytoplankton, dinoflagellates) using an Underwater Ultrasound (5\~15MHz) (5\~15MHz) to study Characteristics of Acoustic Backscattering of Harmful algae. In an effort to detect the harmful algal scatterers with population density of less than 300 cells/ml that corresponds to the precaution stage of red tide, backscattered signals from various scatterer-density samples were obtained and analyzed. Correlations between volume backscattering strength (Sv) and population density (cells/ml) of scatterers in the medium have been investigated. Comparison of Volume Backscattering Strengths calculated with the fluid-sphere model [1] and the measured values showed an agreement.en_US
