Abstract
Increased population and industrial growth leave serious impact on marine environment, hence, effective water quality monitoring for seawaters is of high demand. Traditional water quality monitoring systems follow manual procedures like collecting water samples, testing and analyzing them in laboratories, which is not only costly but also time consuming, and ultimately affecting timely decision making. Due to recent advancements in sensor technology, sensor based environment systems are attracting the researchers and developers by offering several advantages as compared to traditional approaches. Benefiting from the technology, Mariner, a multi-sensor marine platform is developed. Mariner has the ability to monitor a range of water quality parameters, collect and forward the retrieved data to a processing center in real time in order to make timely decision. Mariner has propulsion capability, hence can move from one location to another autonomously. The proposed system is equally suitable for small as well as large water reservoirs, lakes, rivers, fishponds etc. thus promises broad applicability prospects. Real-time results of various monitored parameters were obtained successfully when tested in the Red Sea near Sharma beach. Further, three-dimensional graphs are plotted to assess the influence of depth and time on the observed parameters.
