19/10/2017 Piu Mandal * Langmuir Circulation is a kind of water circulation mainly driven by wind. It is the most important topic in Physical Geography and also most important research topic to the Oceanographer. The study of Langmuir Circulation is quite interdisciplinary, as it is a cross idea from Physics, Chemistry, Biology and Applied Mathematics. Langmuir Circulation process or mixing the ocean layer mainly incorporated with fluxes of momentum, heat, mixing gases across the air-sea interface and transport of nutrients and others. There lies a crucial link in coupling the air and sea for mixing layer in ocean surface. What is Langmuir Circulation? “Langmuir Circulation is shallow, slow, counter-rotating vortices at the ocean's surface aligned with the wind”. These are mainly found when wind blows over the sea surface. This type of circulation is mainly seen when convergence of two nearby cells form a parallel pattern on the water surface. This convergence zone o...

Meanwhile, our drinkable water sources are finite: Less than 1% of the earths freshwater are actually accessible to us. Without ac...
