BASIC STUDY ON THE MONITORING TECHNIQUES FOR BAY ENVIRONMENT BY SENSORS' DEPLOYMENT

Keita Kudoh; Keita Furukawa; Tomonari Okada

It is important to know temporal and spatial change of environment to evaluate its status. Especially, vertical profile and temporal change of water quality are taking an important role on Tokyo Bay environment, since strong stratification and hypoxia in the bottom layer during summer are easily changed by wind driven mixing. However, it is not feasible to obtain a dense data for both vertical and temporal domains for wide area of the bay because of the cost. This research aimed to establish a cost-effective method for the monitoring of vertical profile of the hypoxia by a simple set of a thermistor chain and a dissolved oxygen (DO) sensor. The key factor of success of the method was based on similarity on vertical profile of temperature and DO.
