The Deep Sea Environment In this essay, we will discuss several aspects of the environment of the deep sea. Emphasis will be placed on the environment below the mesopelagic zone extending up to 2000 meters below sea level with an emphasis on environmental areas and Bathypelagic Abyssalpelagic.

We examine the sources of data for analysis of this environment on the high seas looking at some of the techniques people use to gather information there. This will be followed by a description of certain conditions in determining those regions with a note on the geology, sediments, a brief discussion of deep water masses, a description of marine life is the environment in high seas and its adaptations challenges with a special note on hydrothermal vents (but at an average depth of 2100 meters, they are just inside our area of discussion), hydrocarbon seeps and a definitive conclusion on the overall importance the environment for deep humanity.

Firstly, why the study of the environment on the high seas at all? The abyssal plains are dark and appear devoid of life or interest, but nothing could be further from the truth. abyssal areas represent over 90% of the benthos and over 80% of the ocean is below 3000 meters. New discoveries are made and these could greatly influence our future.

The deep sea is a repository of scientific information and resources that can influence us in the fields of medicine, chemistry, physics, biology, to feed the growing world population and conservation. The deep sea is actually the largest ecosystem on Earth. Consider first the methods of evidence collection. Gathering evidence There are various devices and techniques that were used to explore the depths and collect information from the time of abandonment lead weights (lead line) on the side of ships, sounding echo, since the First World War, the invention of scuba gear (not useful to our substantive discussion), the use of long-term geological Asdic tilted (GLORIA). sidescan sonar and continuous seismic survey methods give us a wealth of information.

In addition, a range of simple devices give us information such as thermometers, water bottles and current to measure the physical and chemical properties of water, dredges, corers thermal sensors and cameras to study the bottom sediments and the lower life. However, for centuries the only evidence we had of marine life in deep water has been extremely rare. The area we are talking about has rarely been visited. Scuba diving suits with air (IMD) can cope with about 450 meters now. We need different equipment to explore the depths that we are discussing. In 1964, Alvin made the first successful manned deep sea scientific diving submarine into account the Woods Hole Oceanographic Institute. The updated versions have been able to dive to 6,000 meters.

Alvin was the first to discover the hot springs and explore a small part of the mid ocean ridge. We return to this environment later. For depths greater than this we rely on remotely operated vehicles or ROVs. Advanced research is conducted by Woods Hole Robots OI and Monterey Bay Aquarium Research Institute .. The man has even visited the lowest point. In January 1960 Piccard and Walsh descended in Trieste Part II (a submarine) for point the best known on Earth, the Mariana Trench at 10,915 meters. Despite the general lack of evidence and the fact that the vast majority of the seabed remains to be explored, we can discuss the deepwater environment dynamically.

New discoveries are made frequently in this area. Let now the basis of geological environment of the deep sea. Geology The oceanic lithosphere is about 100 km thick (and therefore substantially thinner than the continental lithosphere) and it is the crust and the upper part.
