During a recent diving trip to the Mariana Trench, The Unmanned Submarine ‘Aishiteru’ collected several water samples that were highly concentrated with unknown microbial communities. Therefore our team need to figure out how the water samples should be transported to the nearest advanced microbiology laboratory to be analyzed. The microbes have to be survived during the long journey.
The Mariana Trench is located in the Pacific Ocean which is east of the 14 Mariana Islands. The Mariana Trench has an 11”21’ North latitude and 142”12’ East longitude which is near Japan. It is actually the deepest part of the earth’s ocean as well as the deepest location of the earth itself. The Mariana Trench was created by a phenomenon which so called ocean-to-ocean subduction. It is a phenomenon which a plate topped by oceanic crust is subducted beneath another plate topped by oceanic crust (The Mariana Trench, 2013). The deepness of Mariana Trench is mainly caused by the western Pacific is home to some of the oldest seafloor in the world. It was investigated. It was about 180 million years old. The formation of seafloor is related to the mid-ocean ridges of lava. The lava is comparatively warm and buoyant when the seafloor is fresh. It would ride high on the underlying mantle. However, the seafloor will become increasingly dense when the lava ages and spreads away from the source. It would cause the seafloor settle ever lower (National Geographic Daily News, 2012).
