摘要

Harmful Algal Blooms (HABs), caused by Cochlodinium species that appear from the middle of August until the end of September, affect economic loss and aquaculture in the southeast coastal waters of Korea. It was studied alongside the HABs with the environmental (meteorological and oceanic) and satellite data in September compared to the data in March, 2010. Chlorophyll-a concentrations were calculated using Sea-viewing Wide Field-of-view Sensor (SeaWiFS) images by an Ocean Color 4 (OC4) algorithm. The cell concentrations of Chlorophyll-a in March was compared to the cell concentrations in September by using the SeaWiFS images. In meteorological data from March, the mean air temperature, the mean wind speed, and the sunshine were 5.87 °C, 3.87m/s and 9.73h/day, respectively. The data from September, the mean air temperature, the mean wind speed, and the sunshine were 19.17 °C, 1.4m/s and 9.03h/day, respectively. Sea Surface Temperature (SST) showed 10.85 °C in March and 22.05 °C in September. The HABs occurred when SST was 25.1 ～26.8°C in September. The cell density of Gymnodinium and the cell density of C. polykrikoides were in a range of 40～3700cells/ml and 80～1300cells/ml. The mean air temperature in September was 13.3 °C higher than the mean air temperature in March. The sunshine duration in March was 0.7 hours longer than the sunshine duration in September. The mean wind speed in September was 2.47m/s faster than the mean wind speed in March. As a result, the HABs was occurred when SST was higher and the wind speed was slower. The sunshine duration has not difference between March and September, but SST and the wind speed were considered to affect the occurrence of HABs.
