World Oceans Day is observed every year on 8 June to create awareness among human beings of the benefits it has enjoyed from the ocean so far. The United Nations (UN) declared World Oceans Day as an official occasion in 2008. The UN has also hosted different themes each year to celebrate the day.

According to the natural tendency of humans, they believe, what they see. To make people aware of the deteriorating condition of  the Earth, satellite images have proved to change people’s perception of their surroundings. Over the years, geospatial and remote sensing technology has helped in environment protection, by providing continuous data to monitor and preserve the vulnerable elements. GIS helped to interpret the data and made it feasible for the users to access it online.  Since the 1960’s continuous launch of land surface monitoring and weather satellites gave enough visual evidence about the dynamic environmental processes globally. Better spatial and temporal resolution is now sufficient to know the changes on the Earth du...
