SUMMARY:Ultra Deep Science Drill Ship
DESCRIPTION:Photo: JAMSTEC \nWhere? Abyss Observatory in JOGrid (OpenSim) \nEnable your OpenSim access here \nhop://jogrid.net:8002/Abyss Observatory/491/302/140 \nWho? Hajime Nishimura\, Japan Agency for Marine-Earth Science and Technology (JAMSTEC)\, \n          Yan Lauria\, Museum director of Abyss Observatory in SL/OpenSim \n  \nAbstract: \nI was working on development of ultra deep science drill ship “Chikyu” (“the Earth” in English) from 2001 to 2005. \nI built 3D model of “Chikyu” in Science Sim (one of OpenSim grids hosted by Intel) as joint project with ScienceCircle Foundation and JAMSTEC in 2011\, but Science Sim was closed and I imported “Chikyu” to JOGrid (Japan Open Grid hosted by Tokyo University of Information Science) in 2014 and continue to improve until now. \n”Chikyu” is first and only science drill ship which has well control capability for core sampling through deeper penetration by 2\,500 m Riser drilling system which has 9\,000 m drill strings\, 2\,500 riser pipes\, Blow Out Preventer (BOP) and mud circulation system for cuttings recovery from drill hole compatible with commercial oil drilling. \nhttps://www.jamstec.go.jp/chikyu/e/ \nIn current phase\, “Chikyu” is engaging at 2\,500 m depth water and drilling 5\,200 m from the seafloor in plate subduction zone under strong Kuroshio current (more than 2 m/sec). \nTarget is seismic zone of the plate interface fault system at a location where it is believed to be capable of seismogenic locking and slip\, and to have slipped coseismically in the 1944 Tonankai earthquake. \nhttp://www.jamstec.go.jp/chikyu/e/nantroseize/expedition_358.html \nIn future phase\, “Chikyu” will be upgraded for 4\,000 m riser and 11\,000m drill strings which enable to reach crust-mantle boundary. \nChikyu’s drill will have to go through 4000m of water and 6000m of crust to be able to reach the mantle\, which makes up roughly 84 percent of our planet’s volume.   \nThe researchers also want to investigate the boundary between the oceanic crust and the mantle to figure out how the crust formed. Plus\, they want to see if microbial life exists that deep inside the planet. \nTo do this requires new techniques to drill out 7\,000 m below the seafloor\, in regions where ambient temperatures can reach 250 degrees C \nhttp://www.gm.univ-montp2.fr/spip/spip.php?rubrique185&lang=en \nRemark; \nI’ll use voice chat in English and Japanese. \nThe region is 512m x 512m (Varregion of OpenSim) and there are huge amount of prims\, so you may be difficult to move depend on your PC and Internet. \nPlease try Hypergrid teleport in advance the presentation. \n  \nAn excursion led by Hajime Nishimura “Ultra Deep Science Drill Ship” at Abyss Observatory in Japan Open Grid (JOGrid) \nHajime Nishimura / Yan Lauria \n  \nPrevious work in the Library \nPrevious work in the Film collection
