This research involves rapid-response activities that allow the study and sampling of a unique and scientifically important hydrothermal spring system in the Zambales ophiolite in the Philippines that is likely to be severely compromised or destroyed by development slated to begin in mid-2010. The springs are unusual and may be terrestrial analogs to undersea ultramafic-hosted hydrothermal vent systems, such as the Lost City system that was discovered a decade ago on the Mid-Atlantic Ridge. Because the Lost City system is costly and difficult to sample and study due to its location thousands of meters below the sea surface, the study of a possible terrestrial analog such as the one at the Zambales ophiolite is crucial for cost effectively improving our understanding of the submarine systems. Rocks, gases, fluids, and microbes from the Zambales springs will be sampled and examined. Research goals are to determine the subsurface water-rock reactions that are driving the chemical and thermal signatures of the site, as well as collect samples of microbes that live in these chemically hostile extreme environments and work with collaborators to determine their genetics. Broader impacts of the work include international collaboration and scientific cooperation between Philippine scientists; training of three graduate students; and support of a PI from a group under-represented in the sciences.

这项研究涉及快速响应活动，对菲律宾三描礼士蛇绿岩中独特且具有科学重要性的热液泉系统进行研究和取样，该系统可能会因 2010 年中期开始的开发而受到严重损害或破坏。 这些泉水很不寻常，可能与海底超镁铁质热液喷口系统类似，例如十年前在大西洋中脊发现的失落之城系统。 由于失落之城系统位于海平面以下数千米，因此成本高昂且难以采样和研究，因此研究可能的陆地类似物（例如三描礼士蛇绿岩中的系统）对于以成本效益的方式提高我们对海底系统的了解至关重要。来自三描礼士泉水的岩石、气体、液体和微生物将被采样和检查。 研究目标是确定驱动该地点化学和热特征的地下水-岩石反应，并收集生活在这些化学恶劣的极端环境中的微生物样本，并与合作者合作确定其遗传学。 这项工作的更广泛影响包括菲律宾科学家之间的国际合作和科学合作；培养三名研究生；以及来自科学界代表性不足的群体的 PI 的支持。
