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

提供资金，使科学家能够参加2010年7月和9月至10月JAMSTEC对马里亚纳弧的两次航行。导致这些巡航获得批准的项目是美国和日本地球科学家之间持续合作的结果。巡航1号将探索和采样关岛和帕甘之间的马里亚纳群岛南部的海底弧火山。八天的潜水与Hyperdolphin 3 K登上R/V夏岛（关岛，关岛; 2010年7月9日至19日），并将重访，检查和采样几个海底火山（特雷西，W。Rota，NW Rota-1，E. Diamante，Zealandia Bank area）. 研究人员还将探索W. Sarigan（在Zealandia银行地区）和Daon火山首次。第二次巡航（关岛-关岛; 9月10日）17-2010年10月1日）继续在2006年和2008年研究的关岛马里亚纳前弧E，S和SW的火成岩基底检查。R/V横须贺号将作为8次新海6500潜水和4次马里亚纳南部前弧深拖相机潜水的母船。为了实现这两个主要目标，调查人员将把工作重点放在三个主要目标地区：关岛东南部的Forearc、圣罗莎浅滩和东南马里亚纳Forearc裂谷。更广泛的影响：这些巡航加强了海洋科学方面的国际合作。它们还加强了学术科学家与USGS和NOAA科学家之间的合作。该项目支持NSF资助的凯利，里根，肖和斯特恩的研究。该项目有助于IODP考察的发展。一名研究生（Julia Ribeiro）的论文研究将直接受益于这次航行，两名年轻科学家（Wada和Guillaume吉拉德）将首次参加海洋地球科学考察。这项研究支持MARGINS SubFac实验和Izu-Bonin-Mariana弧中的焦点位置。

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.
