PROBLEM TO BE SOLVED: To provide an environmental monitoring system measuring a water quality for every depth and an air quality and enabling installation of a sink/float-type preserve at an optimum position for aquaculture on the basis of the measured result.SOLUTION: An environmental monitoring system 1 comprises: water intake means 2 for taking water in a water area where a sink/float-type preserve is installed； a measuring section 3 for measuring a water quality factor of the taken water； and a control section 4 that controls operation of the water intake means 2 and operation of the measuring section 3 and acquires a water quality measurement result measured by the measuring section 3. The water intake means 2 includes water inlets 2a-2c, an intake pipe 2d for sending water to a measurement tank 6, intake valves 2e-2g for switching over one, which the water intake is permitted, out of the water inlets 2a-2c, and an intake pump 2h. The measurement tank 6 includes a container body 9 for storing water, and a water quality sensor 7 for measuring a water quality factor of the water. The control section 4 starts the measurement of the water quality sensor 7 each time a water inlet 2a-2c, the water intake of which is permitted is switched over.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】深度毎の水質や大気質を計測し、計測した結果に基づいて養殖に最適な位置に浮沈式生簀を設置可能な環境モニタリングシステムを提供する。【解決手段】環境モニタリングシステム１は、浮沈式生簀が設置される水域の水を取水する取水手段２と、取水された水の水質ファクターを計測する計測部３と、取水手段２の作動及び計測部３の作動を制御し、計測部３が計測した水質計測結果を取得する制御部４を備え、取水手段２は、取水口２ａ～２ｃと、水を計測槽６に送水する取水管２ｄと、取水口２ａ～２ｃのうちで取水が許可される一つを切り替える取水弁２ｅ～２ｇと、取水ポンプ２ｈを備え、計測槽６は、水を貯留する容器体９と、水の水質ファクターを計測する水質センサー７を備え、制御部４は、取水が許可される取水口２ａ～２ｃが切り替わる毎に水質センサー７の計測を開始させる。【選択図】図１
