The real time monitoring are required to get shot-and long-term variations of temperature, salinity, dissolved oxygen and turbidity in coastal region at all times. The rapid change of these properties crucially affects fish and shell in mariculture near the coast. This study has been carried out to construct a monitoring system of water properties at a particular depth for forecasting upwelled anoxic water near the sea bottom during the period from 2001 to 2003. The field test was made at the fishing mariculture field in Uchiura Bay stating from the summer in 2001. The sensors were installed at 10m depth and the stored data were sent to some stations by E-mail. The test was a successful result except the gradual decrease value of the salinity, dissolved oxygen and turbidity sensors by some adherent micro-lives to the sensors. Then following improvement has been planned and tried ; (1) preparation of temperature array with 100m length, and (2) manufacture of dissolved oxygen sensor. The temperature array and water property-sensor were installed at the other mariculture field, and so the monitoring has continued at both stations from April 2002 and three stations from April 2003. The temperature observations gave the information of the water exchange, internal wave, and upwelling in the coastal region, and these data are useful information to avoid mortality of the fish in the mariculture by fishermen who receive the data by E-mail. The dissolved sensor is improved to avoid the adherent micro-lives to the sensors and will be installed at the field in Uchiura Bay from June 2004.

对近岸海域的温度、盐度、溶解氧、浊度等水质参数进行真实的实时监测，以获得其短时和长期的变化规律。这些特性的快速变化对沿海养殖的鱼类和贝类产生了至关重要的影响。本研究旨在建立一个特定深度的水质监测系统，以预测2001 - 2003年期间近海底缺氧水体的涌升。从2001年夏天开始，在内浦湾的渔业海水养殖场进行了现场试验。传感器安装在10米深处，存储的数据通过电子邮件发送到一些站点。除盐度、溶解氧和浊度传感器被附着在传感器上的一些微生物逐渐降低值外，试验是成功的。在此基础上，进行了以下改进和尝试：（1）100米长温度阵列的制备;（2）溶解氧传感器的制作。在另一个海水养殖场安装了温度阵列和水质传感器，因此从2002年4月开始在两个监测站和2003年4月开始在三个监测站继续监测。温度观测给出了沿海地区的水交换、内波和上升流的信息，这些数据对于通过电子邮件接收数据的渔民在海水养殖中避免鱼类死亡是有用的信息。对溶解传感器进行了改进，以避免粘附在传感器上的微生物，并将从2004年6月起安装在内浦湾的现场。
