New dives with the Japanese Marine Sciences and Technology Center (JAMSTEC) ROV Kaiko and submersible Shinkai 6500 collected 106 new shield-stage tholeiites from the distal Hana Ridge representing early phases of Haleakala shield growth. The PI participated in these dive efforts and spent time at Tokyo Institute of Technology (TITech) and JAMSTEC working with Professor Eiichi Takahashi, the Japanese program PI, on geochemical analyses for a pilot Hana Ridge project. This award for a three year project will be used to carry out electron microprobe major and minor element and Cl, F, and S analyses of all volcanic glasses recovered (~75-90 samples), bulk rock ICP-MS (~40-50 samples) and laser ablation ICP-MS glass analyses (~75 samples) for trace elements, and isotope analyses on 20-25 samples in years 1 & 2. Separate travel funds will be sought from NSF-INT for the period of time to be spent in Japan. Year three of this project will be spent synthesizing the data collected by the various research groups and writing up the results together.

日本海洋科学和技术中心（JAMSTEC）的新潜水器Shakaiko和潜水器Shinkai 6500从Hana山脊的远端收集了106个新的盾牌阶段拉斑玄武岩，代表Haleakala盾牌生长的早期阶段。PI参与了这些潜水工作，并在东京工业大学（TITech）和JAMSTEC与日本PI项目的Eiichi Takahashi教授合作，为Hana Ridge试点项目进行地球化学分析。 这项为期三年的项目将用于对回收的所有火山玻璃（约75-90个样品）进行电子微探针主要和次要元素以及Cl，F和S分析，散装岩石ICP-MS（约40-50个样品）和激光烧蚀ICP-MS玻璃分析（约75个样品）的微量元素，以及12年20-25个样品的同位素分析。将从NSF-INT寻求单独的旅行资金，用于在日本度过的时间。这个项目的第三年将综合各个研究小组收集的数据，并将结果写在一起。
