Reading the ocean is full of magic and mystery. The documentary transcript below describes the amazing world beneath the the ocean. Before you read the transcript, think about the following questions. What do you know about the world beneath the ocean? Would you dive to the ocean bottom if you had the chance? Why or why not? The ocean deep, we look upwards and wonder what lies beyond our planet. We send probes into the vastness of space to explore the unknown. We build space stations to advance our understanding of the universe. Our curiosity about outer space has remained an unshakable. Meanwhile, IT is estimated that more than eighty percent of the world's oceans are unexplored. So if we want to find exciting new life forms as well as undiscovered, an unusual geological formation, the ocean is where we should also be looking. Then why don't we dive to the bottom of a really deep ocean and take a long close look beneath the waves? The first two hundred meters of our dive takes us through what can be called the open ocean, where most visible light exists. He lives much of the marine life we know about, such as dolphins, corals and seaweeds. Sinking below two hundred meters, we enter the twilight zone where there is little sunlight, and that's almost no planned life. Most of the fish living here are small filter fears, which swim up at night to feed in the nutrient rich waters above. Also living in the twilight zone, our hunters with telescopic upward pointing ice that can easily spot a meal in the waters above. Consequently, the fish most likely to be eaten have evolved to have thin bodies so that they are less easily seen from below. However, once they are captured, the hunters backward curving teeth prevent them from getting away. Evolution, IT seems, helps both the hunter and the hunted in equal measure. Once past one thousand meters, we have reached the deep motion where there is no light in. Temperatures drop just above freezing. The pressures are huge and can be more than one hundred times the pressure of the earth's atmosphere. IT is then surprising that many creatures can live in this extreme environment. They cannot realize solely on the rice side to survive and have evolved fascinating survival characteristics. Indeed, many organisms in the deep potion are blind. In order to obtain food and avoid being caught, they have to depend on other senses, such as smell and their ability to detect slight changes in water pressure. Also, some fish have both male and female organs to increase the chances of reproduction as fish are so scarce at these depths that IT can be difficult for them to find a mate. The fish in the deep ocean are among the strangest creatures on the earth, many of which have yet to be properly studied. On reaching the ocean floor, we may see shrimps in other organisms around hybrid erma vents. These vents form in volcanically active areas, pouring mineral rich fluids into the sea. Before the discovery of these creatures, IT was thought that all life on the earth obtained its energy from the sun. However, this discovery has revealed that life forms can obtain nutrient and energy from thermal sources. Knowing that life can exist in these extreme conditions has changed scientific opinion about the chances of their being life elsewhere in the universe. In addition to the vents and remarkable organisms, we cannot miss the marianna trench located in the northwestern part of the ocean. Its deepest point, known as the chAllenger deep, is nearly eleven thousand meters below sea level. You could place mount kalan ma. In the chAllenger deep, and its top would still be more than two thousand meters below the surface while there is little life at such great depths, IT is far from boring. Of the many strange geological formations to be found. Here are rock bridges which cross the trench, some reaching a height of two thousand five hundred meters above the chAllenger deep. As you can see, the world beneath the surface of the ocean is indeed an amazing place. On our journey down, we have been fascinated by incredible geological formations as well as unexpected life forms that have become strAngely adapted to their extreme environment. With so much of the oceans left to explore, who knows what wanders still await us in the future.
