Environmental Applications of Aquatic Remote Sensing

Several lakes, coastal zones and oceans are directly or indirectly influenced by human actions. Through the outlet of a large amount of materials in the air and water, we’re altering the natural conditions on local and global levels. Remote sensing sensors, on satellites or planes, can easily acquire graphic data, offering the user with details about the portrayed location, object or phenomenon. Three diverse programs are mentioned within this thesis. In the 1st part of this project (Environmental Applications of Aquatic Remote Sensing), we’ve utilized a bio-optical model to obtain info about water quality factors from remote sensing data collected. In the 2nd part, remote sensing data have been utilized to locate and map waste water plumes from pulp and paper industries along the east coast of Sweden. As a final point, in the 3rd section of this report (Environmental Applications of Aquatic Remote Sensing), we’ve reviewed to what extent satellite data may be used to keep track of coral reefs and identify coral bleaching.Irrespective of application, it is very important to understand the limits of this method. Nevertheless, this method gives us an opportunity to keep track of the environment, in this instance the aquatic environment, with a superior spatial coverage…
