Exploring the Underwater World
Most of our planet is filled with water, about 70 percent, while there are many places that have not yet been discovered. Seas greatly influence the earth's planet environment, while the ocean provides important living and nonliving resources. The ocean defines the feature of our planet and is crucial to life on earth. However, it remains one of the planet's last unexplored boundaries. At the same time, oil and natural gas are the most valuable non-living resources taken from the oceans.
New ideas have traveled through the centuries and inspired people to dive and explore below the surface. Sea explorations are indispensable not only for investigating marine creatures and other resources hidden under the deep water but also for geophysical research into the structure and behavior of the earth (Cui et al. et al. 2013). The marine industry plays a key role in researching and studying those science and engineering fields relevant to this issue, such as the ocean environment, which are considered a matter of high-level priority. By the way, the marine industry, as a vital part of the global economy, is responsible for over 90% of the world's trade. Without sea transport, the world economy would collapse. Nowadays, it is demanded to use new and specific technologies to overcome new appeared needs due to achievements and development in the field of construction, installation, maintenance of offshore structures and deep-water platforms, or environmental research.
In the beginning, the underwater world was explored by divers who started using the new world mainly for food or fulfilling demanded resources. By developing and appearing new human needs and understanding the subsea potential, humans try to find new ways to take advantage of the underwater benefits. This need revealed a competition for better and more efficient use of aquatic resources. This leads to using instruments or devices which are gone deeper with more abilities to explore. Consequently, new methods, devices, and knowledge are developed this way.
Researchers have traditionally used ships to photograph the depths, drop floats and drifters into the currents, and collect water, rock, and marine life samples. Over the last few decades, engineers have developed underwater vehicle technologies capable of meeting the many challenges the deep sea imposes. The underwater vehicles are categorized into main fields of manned and unmanned vehicles. Although unmanned submarines such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) have some advantages in certain aspects, human-operated vehicles (HOVs) remain the central element. This is due to the sense of vision, the most important of all the five human senses. (WHOI, Cui et al. 2013).
