JOGMECCRFC12016 Env Template 2016 nematoda DNA

Sampling data captured in Oceanic Exploration Research JOGMEC has implemented the following works as the crust exploration activities during the year 2016: (1) Exploration work A sampling survey, acoustic survey, and seafloor observation were conducted according to the exploration plan. The exploration target was the JA02 Seamount and BMS drilling, ROV survey, MBES survey were performed with the marine resource research vessel Hakurei owned by JOGMEC during a period of 29 days from April 11 to May 9. In the BMS drilling, 25 holes were drilled at 13 sites to collect 22 core samples. In the ROV survey, 278 kg of samples were collected for benefication and metallurgy tests. In the MBES survey, benthic landform data including the foot of the JA02 seamount were collected. In addition to the surveys with Hakurei, automatic measurement of the crust thickness was conducted at the JA02 Seamount with a chartered vessel owned by a private company during a period of 21 days from February 3 to 23. Although the actual survey could be made only for two days due to bad weather, we made 3D mapping of the acoustic measurement result of the crust thickness on the benthic plane. The measured crust thickness was found consistent with the BMS data collected from the surrounding area.

大洋勘探研究采集的采样数据
日本石油天然气金属矿物资源机构（JOGMEC）于2016年开展了如下地壳勘探工作：
(1) 勘探作业：依据勘探计划实施采样调查、声学调查与海底观测。本次勘探目标为JA02海山与BMS钻探作业；JOGMEC所属的"Hakurei"号海洋资源调查船于4月11日至5月9日的29天作业周期内，完成了BMS钻探、ROV（遥控无人潜水器，Remotely Operated Vehicle）调查与MBES（多波束测深系统，Multi-Beam Echo Sounder）作业。
在BMS钻探环节中，于13个站位钻取25个钻孔，共计采集22份岩芯样品；在ROV调查环节中，采集278千克样品用于选矿与冶金测试；在MBES调查环节中，采集了包含JA02海山山麓在内的海底地形数据。
除依托"Hakurei"号开展的调查作业外，项目团队于2月3日至23日的21天周期内，租用私营企业所属船只在JA02海山区域开展地壳厚度自动测量工作。尽管受恶劣天气影响，实际仅完成2天的测量作业，但已基于声学测量结果完成海底平面地壳厚度的三维制图。实测地壳厚度与周边区域采集的BMS数据具有良好一致性。
