By understanding the influence of the concentration of chlorophyll a due to a change in the temperature, an annual trend of green tide and red tide generation can be determined and data on climate change and marine environment change can be obtained. Also, the present invention enables real-time broadband surveillance by which early warning on a frequent occurrence area of red tide and green tide is possible, thereby enabling efficient disaster prevention at an early stage and thus contributing to damage reduction. In addition, the present invention can apply various platforms such as personal carriage, embedding in a ship, and fixing at a coast, and ensure high sensitivity, night surveillance function, real-time monitoring, and broadband scanning investigation.
