Our Earth's surface is covered by water up to 71%. Even thought the ocean's surface is exploited for fishing, transportation and scientific researches, the deepest part of the world's oceans continues to be untouched by any humans. The deepest seas has many untold mysteries, legends and stories which keep Mankind asking for more and searching for answers for thousands of questions.The deep sea is the part of the ocean below a depth of 200 metres that is in permanent darkness. The abyss, with an average depth of 3.8 kilometres, is the most common environment on Earth.The sea floor is covered by vast plains of soft sediments made up of fine detritus and particles that drift down from the surface. The water is cold because it comes from the polar regions, and its weight puts considerable pressure on life at the bottom of the sea.Although the deep sea floor has no plants, our studies show that it is extremely diverse in animal species, often having many more than shallow water.

ShoreLine Change Monitoring in Coastal India, Using Remote Sensing and GIS Tools
IntroductionShoreline or coastline, the boundary between land and sea keeps changing its shape and position continuously due to dynamic environmental conditions. The change in shoreline is mainly associated with waves, tides, winds, periodic storms, sealevel change, the geomorphic processes of erosion and accretion and human activities. Shoreline also depicts the recent formations and destructions that have happened along the shore. Waves change the coastline morphology and forms the distinctive coastal landforms. The loose granular sediments continuously respond to the ever-changing waves and currents. The beach profile is important, in that it can be viewed as an effective natural mechanism, which causes waves to break and dissipate their energy. When breakwaters are constructed, they upset the natural equilibrium between the sources of beach sediment and the littoral drift pattern. In response, shoreline changes its configuration in attempt to reach a new equilibrium (Ramesh … [Read more...] about ShoreLine Change Monitoring in Coastal India, Using Remote Sensing and GIS Tools
