INTRODUCTION
The ocean covers some 70% of our planet and is a rich fund of information on global health, climate change, and resource degradation. Studying marine ecosystems, ensuring port security, and monitoring oil pipelines and leaks of hazardous materials in transit are some of the specific reasons for profiling the concentration and distribution of substances in the ocean.
Considerable research has been conducted to develop and assess methods of sensing the ocean on spatial and temporal scales ranging fr ....etc

high speed underwater acoustic modems is shown in this paper. high speed digital communication and broadband underwater acoustics technologies have been combined to achieve this . increased data rate and decreased power consumption is achieved by Broadband Spread Spectrum Technology. The underwater communication has to deal with noises such as offshore drilling noise, ambient noise, ship noise etc. no communication errors has been seen to appear with these noises.
Broadband Spread Spectrum Technology us implemented ....etc

Respected Mam/Sir
can you please send me ppt on underwater wireless communication, i am doing 3rd year ECE, i need ppt for a reference.
Abstract
While wireless communication technology today has become part of our daily life, the idea of wireless undersea communications may still seem far-fetched. However, research has been active for over a decade on designing the methods for wireless information transmission underwater. Human knowledge and understanding of the world’s oceans, which constitute the major part of our planet, rests on our a ....etc
