Objective
Elucidating the occurrence of rocks in the inside corner high of the northern-end of the CIR Segment1,northern part of the Hakuho-knoll hosting the Kairei hydrothermal field ; Obtaining the crustal structure (especially faults) in the shallow part of the oceanic crust at the region between the Hakuho-knoll and URANIWA Hills 16 using Single Channel Seismic (SCS) ; Measuring heat flow by the Stand-Alone Heat Flow meter (SAHF) at the URANIWA Hills ; Obtaining glycan profiles from both host animals and their symbiotic bacteria ; Performing wide array of "-omics" analyses,such as community genomic,proteomic,transcriptomic analyses,on both host animals and their symbiotic bacteria ; Cultivating and isolating epi-or endo-symbiotic bacteria and free-living counterparts ; Characterizing larvae of hydrothermal vent animals ; Keeping hydrothermal animals alive and transporting them to Japan
