The deep sea is the largest habitat on earth and is largely unexplored. More people have traveled into space than have traveled to the deep ocean realm. The Blue Planet Seas of Life. Most people familiar with the oceans know about life only in the intertidal zone, where the water meets land, and the epipelagic zone, the upper sunlit zone of the open ocean. Though these zones contain an abundance of ocean life because sunlight is available for photosynthesis, they make up only a small fraction of the ocean biome. In fact, most of the ocean is cold, dark and deep. It is important to realize that photosynthesis occurs only down to about 1. Mariana Trench To get an idea of how vast the oceans depths are, consider that 7. Until recently, the deep sea was largely unexplored. But advances in deep sea submersibles and image capturing and sampling technologies are increasing the opportunities for marine biologists to observe and uncover the mysteries of the deep ocean realm. Creatures 2 Crack' title='Creatures 2 Crack' />Deep sea research is vital because this area is such an enormous part of the biosphere. Despite its depth and distance, it is still our backyard in comparison to outer space. And yet, human exploration has revealed more detail about the surface of the moon and Mars that it has about the deep sea Consider that hydrothermal vents and their unique organisms, which revolutionized our ideas about energy sources and the adaptability of life, were only discovered in 1. There may be yet other life altering discoveries to be found at the bottom of the ocean. The oceans are divided into two broad realms the pelagic and the benthic.

Organisms living there are called the pelagos. Creatures 2 Crack' title='Creatures 2 Crack' />Monsters are a network of various creatures, which include manmade abominations, legendary. From the shallowest to the deepest, biologists divide the pelagic into the epipelagic less than 2. The last three zones have no sunlight at all. Benthic zones are defined as the bottom sediments and other surfaces of a body of water such as an ocean or a lake. Organisms living in this zone are called benthos. They live in a close relationship with the bottom of the sea, with many of them permanently attached to it, some burrowed in it, others swimming just above it. In oceanic environments, benthic habitats are zoned by depth, generally corresponding to the comparable pelagic zones the intertidal where sea meets land, with no pelagic equivalent, the subtidal the continental shelves, to about 2. There are several types of deep benthic surfaces, each having different life forms. First, most of the deep seafloor consists of mud very fine sediment particles or ooze defined as mud with a high percentage of organic remains due to the accumulation of pelagic organisms that sink after they die. Unlike the shoreline, sandy habitats are rarely found in the deep sea because sand particles, created by wave action on coral and rocks at shorelines, are too heavy to be carried by currents to the deep. Second, benthic areas too steep for sediment to stick are rocky. Rocky areas are found on the flanks of islands, seamounts, rocky banks, on mid ocean ridges and their rift valleys, and some parts of continental slopes. At the mid ocean ridges, where magma wells up and pushes seafloor tectonic plates apart, even flat surfaces are rocky because these areas are too geologically new to have accumulated much mud or ooze. Third, in some areas certain chemical reactions produce unique benthic formations. The best known of these formations are the smoker chimneys created by hydrothermal vents, which are described in detail below. Exploration of these zones has presented a challenge to scientists for decades and much remains to be discovered. However, advances in technology are increasingly allowing scientists to learn more about the strange and mysterious life that exists in this harsh environment.

Here are new images and details about 6 of the most important ones you need to know. Life is a British nature documentary series created and produced by the BBC in association with The Open University. It was first broadcast as part of the BBCs.

To learn more about deep sea marine life, sophisticated data collection devices have been developed to collect observations and even geological and biological samples from the deep. First, advances in observational equipment such as fiber optics that use LED light and low light cameras has increased our understanding of the behaviors and characteristics of deep sea creatures in their natural habitat. Such equipment may be deployed on permanent subsea stations connected to land by fiber optic cables, or on lander devices which drop to the seafloor and which are later retrieved typically after a radio command activates the dropping of ballast so the lander may float up. Second, remotely operated vehicles ROVs have been used underwater since the 1. ROVs are basically unmanned submarine robots with umbilical cables used to transmit data between the vehicle and researcher for remote operation in areas where diving is constrained by physical hazards. ROVs are often fitted with video and still cameras as well as with mechanical tools such as mechanical arms for specimen retrieval and measurements. Other unmanned submarine robots include AUVs autonomous undersea vehicles that operate without a cable, and the USAs new Nereus, a hybrid unmanned sub which can switch from ROV to AUV mode and which is currently the worlds only unmanned submarine capable of reaching the deepest trenches. Third, manned deep sea submersibles are also used to explore the oceans depths. Alvin is an American deep sea submersible built in 1. Like ROVs, it has cameras and mechanical arms. This sub, which carries 3 people typically a pilot and 2 scientists, has been used for more than 4,0. France, Japan and Russia have similar manned scientific submersibles that can reach somewhat greater depths, while China is currently building one to reach 7,0. The bathyscaphe Trieste at the National Museum of the U. S. Navy in Washington, D. C. Until 2. 01. 2, only one manned submarine device has ever reached the bottom of Mariana trench at almost 1. Trieste manned by Jacques Piccard and Don Walsh. During the Triestes single dive in 1. March 2. 5, 2. 01. Crusaders Of The Dark Savant Save Game Editor there. March 2. 6 local time, James Cameron successfully dove in his commissioned one man sub to the Challenger Deep. Don Walsh was invited to join the expedition. Physical Characteristics of the Deep Sea. The physical characteristics that deep sea life must contend with to survive are abiotic non living ones, namely light or lack thereof, pressure, currents, temperature, oxygen, nutrients and other chemicals andbiotic ones, that is, other organisms that may be potential predators, food, mates, competitors or symbionts. All these factors have led to fascinating adaptions of deep sea life for sensing, feeding, reproducing, moving, and avoiding being eaten by predators. Light. The deep sea begins below about 2. From there to about 1,0. This faint light is deep blue in color because all the other colors of light are absorbed at depth. The deepest ocean waters below 1,0. And yet, there IS some light. People who dive deep in a submersible with its lights off are often mesmerized by an incredible light show of floating, swirling, zooming flashes of light. This is bioluminescence, a chemical reaction in a microbe or animal body that creates light without heat, and it is very common.
