Abstract
The harmful algal blooms (HABs) are affecting the ecosystems, coastal fisheries, and social economics in Korea. In case of 2013 summer season, massive damage due to HABs (species: Cochlodinium polykrikoides) was reached to $ 23 million during August, 2013 in KOREA. The most important things for minimizing of HABs damage is rapidly detection in initial stage. For the purpose, we has been developed a real-time HABs detection system using ultrasound. The integrated system is composed by several sensors (3.5 MHz frequency, temperature and salinity, Chlorophyll, Dissolved oxygen), power supply, network communication and remote control modules. For evaluating performance of the developed system, several experiments were intensively implemented in the laboratory and in-situ environments during summer seasons, 2013-2016. As the result, both of the performance tests are confirming the acoustic backscattering signal increases with the number of C. polykrikoides. Furthermore, the integrated system shows successfully in-situ performance for real-time red-tide detection and corresponding environmental data.ing August, 2013 in KOREA.
