SGER: High Resolution Lava Surface Dating and Mapping for a 2005-6 volcanic event in the 8-11 N EPR ISS

2006年4月，R/V Knorr号在50度9度的海底地震仪进行例行停止工作时，观测到最近可能爆发的证据。它是美国国家科学基金会资助的Ridge2000项目的三个综合研究地点之一。证据的性质和地点的重要性迫使美国国家科学基金会于2006年5月在“新地平线”号上启动了对该地点的快速部署反应巡航，并于2006年6月/ 7月在“亚特兰蒂斯”号上使用“阿尔文”号潜水器进行了后续巡航。该奖项为对这三次考察中发现的少量岩石进行短熔丝放射性同位素分析提供了支持。该奖项将允许PI在特征最高的时候对熔岩进行钋测年分析，并参加6月/ 7月的考察，届时将有可能通过直接目视观察在现场获得高价值的熔岩样本。该奖项将涉及研究生，并将对R2K社区有用，特别是那些在9N ISS工作的人。

AbstractEvidence for a probable recent eruption was observed during a routine stop of the R/V Knorr in April 2006 to service sea floor seismometers at 9 degrees 50.N on the East Pacific Rise (EPR), which is in one of three Integrated Study Sites (ISS) of the NSF sponsored Ridge2000 program. The nature of the evidence and the importance of the location compelled NSF to launch a rapid deployment response cruise to the site on the R/V New Horizon in May 2006 and a follow up cruise on the R/V Atlantis in June/July2006 using the submersible Alvin. This award provides support to conduct short-fuse radioisotope analyses on a handful of rocks recovered on these three expeditions. This award will allow the PI to carry out Polonium dating analysis on lavas while the signature is highest and to participate in the June/July expedition where high value lava samples will likely be obtained in situ with direct visual observation. This award will involve graduate students and will be useful to the R2K community, especially those working in the 9N ISS.
