International Collaborative Research: Evolution of the Hawaiian Plume- Geochemical Studies of Hana Ridge, Haleakala, Hawaii

日本海洋科学技术中心（JAMSTEC）的ROV Kaiko和潜水器Shinkai 6500在Hana Ridge远端收集了106个新的盾状拉斑岩，代表了Haleakala盾状生长的早期阶段。PI参与了这些潜水工作，并在东京工业大学（TITech）和JAMSTEC与日本项目PI Eiichi Takahashi教授一起为Hana Ridge试点项目进行地球化学分析。该项目为期三年，将用于对所有回收的火山玻璃（~75-90个样品）进行电子探针主要元素和次要元素以及Cl， F和S分析，块状岩石ICP-MS（~40-50个样品）和激光烧蚀ICP-MS玻璃（~75个样品）进行微量元素分析，以及对20-25个样品进行同位素分析。将向NSF-INT申请在日本期间的单独旅行经费。这个项目的第三年将用于综合各个研究小组收集的数据，并共同撰写结果。

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.
