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.

2006年4月，在美国国家科学基金会资助的Ridge 2000项目的三个综合研究点之一的东太平洋海隆（EPR）上，克诺尔号在9度50.N的海底地震仪上进行例行停留，期间观察到了最近可能爆发的证据。证据的性质和地点的重要性迫使NSF于2006年5月在R/V New Horizon上对现场进行快速部署响应巡航，并于2006年6月/7月使用潜水器Alvin在R/V Atlantis上进行后续巡航。 该奖项提供支持，对这三次探险中发现的少数岩石进行短熔放射性同位素分析。 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月的探险，在那里可能会通过直接目视观察就地获得高价值的熔岩样本。该奖项将涉及研究生，并将有助于R2 K社区，特别是那些在9 N国际空间站工作的人。
