Study of Internal Waves Near Eastern Coast of Andhra Pradesh
摘要
The oceans are among the most valuable natural resources known to humankind. They are dynamic complex structures providing abundant resources that support a myriad of life forms. They appear to be endless supplies of both food and transportation due of their vastness. But in recent years, humans have started to push the oceans’ limits, and it is time to consider applying administering them in a more sustainable manner. And to utilize the oceans in more sustainable manner, for that understanding how ocean work and what are the processes that affect oceans. Internal wave plays very significant role in dynamics of World Ocean by the mixing of ocean waters by assisting in the downward movement of warm surface waters and the absorption of heat from the atmosphere. Objective of this study is to understand the generation, propagation and dispersion of internal tides near eastern coast of Andhra Pradesh. Internal waves can cause considerable mixing and the production of turbulence regions, which significantly contribute to the formation of the bottom topography and have an impact on the ecology and underwater portions of hydraulic infrastructure. It has an immediate impact on the economic activities carried out by people. In coastal environments, they have the potential to transport nutrients upward into the euphotic zone and transport heat, momentum, nutrients, pollutants, sediment, and even biota such as larvae. Breaking of internal waves mix the water together changing the density and thereby affecting the large ocean currents which play an important part in the world climate and although this exchange of energy is very important for climate models it has not yet been included. Therefore it is important to know exactly where and how the internal waves are generated as well as where and how they break, for that this study uses remotely sensed satellite data.
