To meet this requirement, an underwater microscope with an electrically controlled variable lens was designed and tested. The captured microscopic images of corals, sediments, planktons, and microplastic revealed their physical, biological, and morphological characteristics. Further studies of the images also revealed the growth, degradation, and bleaching patterns of corals; the presence of plankton communities; and the types of microplastics. The imaging performance is majorly influenced by the choice of lenses, camera selection, and lighting method. Image dehazing, global saturation masks, and image histograms were used to extract the image features. Fundamental experimental proof was obtained with micro-scale images of corals, sediments, planktons, and microplastic at different magnifications. The designed...

This robot is able to move on a variety of surfaces, also having capability of Picking and Placing of various objects and overcome the dangerous areas. The unmanned system is controlled wirelessly using Xbee wireless communication technology. A camera is attached on this mobile robot for live feedback purpose. Many experiments are conducted to test the potential and performance of the robot.

The literature reviews, along with satellite images and tidal data were analyzed to investigate the causes and impacts of seawater intrusion along the coastal areas of Badin and Sujawal districts of Sindh. This study represents that seawater intrusion has taken place up to 70 km upstream from the mouth of Tidal Link Canal and about 2.95 million acres agricultural land has been affected by seawater intrusion. Meanwhile, on the basis of satellite data 30 m year-1 average erosion rate was estimated for the past 17 years in tidal link canal. However sea water intrusion and coastal erosion are have a devastating environmental and social impact along the Left Bank Outfall Drain site, thus the whole ecosystem of lakes is facing serious threat. The fresh water lakes as well as agricultural lands and ground water have been affected by seawater intrusion and coastal erosion. During the southwest monsoon, the neighboring sea in the south inundates vast area with salt water through tidal link drain. Extensive field investigations and a high resolution coastal ocean model are urgently needed for future study to fully understand the dynamic process in this coastal region.
