This RAPID award will support the collection and storage of a rock core to be extracted during a U.S. Army-funded drilling project that is scheduled to start in February-March. Two, 2 km deep boreholes, will be drilled into the Army's Pohakuloa Training Area - located near the center of the Big Island of Hawaii in the Humu'ula Saddle region between Mauna Kea and Mauna Loa volcanoes. One year of continuous rock coring is anticipated. The core itself promises to hold important insight into outstanding scientific problems related to mantle melting, and the internal structure and evolution of Hawaiian volcanoes. The U.S Army's interest is in finding a potable water source for the region and they are willing to allow the team of geologists access to the rock core. This RAPID will support the infrastructure needed to properly clean, label, describe, and store the rock core that will be extracted in the drilling process, providing the greater geological community access to these unique samples that will be responsibly archived for future scientific analyses.The opportunity to analyze 2 km of continuous stratigraphy of a Hawaiian volcano is certainly rare, yet presents a fundamental way by which to gather information about processes that occur from the Earth's mantle to the surface. The location of this core is distinct from any previous drill site in Hawaii, which will enable a more complete regional sampling to address questions specifically related to the internal structure of Mauna Kea volcano. The rationale for the RAPID is to ensure that the core is properly archived so that this unique opportunity to obtain these samples is not lost.

这一快速奖励将支持收集和储存一个岩芯，该岩芯将在美国军队资助的钻探项目中提取，该项目计划于2-3月开始。两个2公里深的钻孔将被钻入陆军的波哈库洛亚训练区-位于夏威夷大岛中心附近，位于莫纳克亚火山和莫纳罗亚火山之间的胡穆拉马鞍区。预计将持续一年进行岩石取心。核心本身有望对与地幔融化有关的突出科学问题以及夏威夷火山的内部结构和演化拥有重要的洞察力。美军感兴趣的是为该地区寻找饮用水水源，他们愿意允许地质学家团队进入岩芯。这一快速将支持适当地清理、标记、描述和存储在钻探过程中提取的岩芯所需的基础设施，为地质界提供更多访问这些独特样本的机会，这些样本将被负责任地存档供未来科学分析。分析夏威夷火山2公里连续地层学的机会当然是罕见的，但它提供了一种基本的方式来收集从地幔到地表的过程信息。这个核心的位置与夏威夷以前的任何钻探地点都不同，这将使更完整的区域采样能够解决具体与莫纳克亚火山内部结构有关的问题。快速调查的理由是确保岩心得到适当的存档，这样才不会失去获得这些样品的独特机会。
