RAPID: US Scientific Participation in Two JAMSTEC Cruises to Study the Mariana Arc

提供资金，允许科学家参加JAMSTEC在7月和9月至10月前往马里亚纳弧的两次游轮。2010年。导致这些邮轮获批的项目是美国和日本地球科学家之间持续合作的结果。邮轮一号将探索和采样位于关岛和异教徒之间的马里亚纳群岛南部的海底弧形火山。在R/V Natsushima(关岛，2010年7月9日至19日)上与超级海豚3K一起进行为期8天的ROV潜水，并将重访、检查和采样几座海底火山(Tracey、W.Rota、NW Rota-1、E.Diamante、西兰迪亚岸区)。调查人员还将首次探索西兰迪亚河岸地区的W.Sarigan火山和Daon火山。邮轮2(关岛-关岛；9月17-2010年10月1日)继续2006年和2008年对关岛马里亚纳前弧E、S和西南部进行的火成岩基底研究。横须贺号将作为母舰，在马里亚纳岛南部的弧前区进行8次新海6500次潜水和4次深海拖曳相机潜水。为了实现这两个主要目标，调查人员将把他们的工作重点放在三个主要目标地区：关岛东南的弧前、圣罗莎浅滩和东南部马里亚纳弧前裂谷。更广泛的影响：这些邮轮加强了海洋科学领域的国际合作。它们还加强了学术科学家与美国地质调查局和美国国家海洋和大气局之间的合作。该项目支持美国国家科学基金会资助的凯利、里根、肖和斯特恩的研究。该项目有助于IODP探险队的发展。一名研究生(Julia Ribeiro)的论文研究将直接受益于邮轮，两名年轻科学家(Wada和Guillaume Girard)将首次参加海洋地球科学考察。这项研究支持边缘次相实验和伊豆-博宁-马里亚纳弧区的焦点位置。

Funding is provided to allow scientists to participate in two JAMSTEC cruises to the Mariana arc in July and Sept-Oct. 2010. The projects that led to the approval of these cruises resulted from ongoing collaboration between US and Japanese geoscientists. Cruise 1 will explore and sample submarine arc volcanoes in the southern Marianas between Guam and Pagan. Eight days of ROV diving with Hyperdolphin 3K aboard the R/V Natsushima (Guam-Guam; July 9-19, 2010) and will revisit, examine and sample several submarine volcanoes (Tracey, W. Rota, NW Rota-1, E. Diamante, Zealandia Bank area). The investigators will also explore W. Sarigan (in the Zealandia bank area) and Daon volcanoes for the first time. Cruise 2 (Guam-Guam; Sept. 17-Oct 1, 2010) continues igneous basement examinations of the Mariana forearc E, S, and SW of Guam that were studied in 2006 and 2008. The R/V Yokosuka will be mothership for 8 Shinkai 6500 dives and four Deep-tow camera dives in the southern Mariana forearc. In order to achieve the two major objectives, the investigators will focus their work on three major target areas: Forearc southeast of Guam, Santa Rosa Bank and the SE Mariana Forearc Rift. Broader Impacts: These cruises enhance international collaboration in the marine sciences. They also enhance collaboration between academic scientists and those with the USGS and NOAA. This project supports NSF-funded research of Kelley, Reagan, Shaw, and Stern. This project helps development of an IODP expedition. Dissertation research of one graduate student (Julia Ribeiro) will directly benefit from the cruise, and two young scientists (Wada and Guillaume Girard) will participate in a marine geoscientific expedition for the first time. This research supports the MARGINS SubFac experiment and the focus site in the Izu-Bonin-Mariana arc.
