A Deepest Depth ROV for Sediment Sampling and Its Sea Trial Result

Recently, a number of bacteria have been found from a mud sample of Challenger Deep in the Mariana Trench. Sampling those sediment samples, an ROV to the oceans' deepest depth is needed. But no vehicle gets to the deepest depth in the world. Scientists want to continuously explore the deepest parts of the oceans with a vehicle equipped with sediment samplers. JAMSTEC started developing a sediment sampling system from April 2005. The system consists of a sampling station and a sediment probe. The station contains two types of bottom samplers. One launches the probe to make a preliminary survey, launching the sampler to obtain a sample. We carried out a sea trial on January 5-7, 2007 in Sagami Bay and was successfully completed. The ROV took a mud sample by using the gravity core sampler.
