9634772 Collier This project is a rapid response to a hydrothermal/volcanic event on the Gorda Ridge in the northeast Pacific. On 28 Feb. 1996 a major seismic event was detected by the NOAA VENTS program through monitoring of the US Navy SOSUS hydrophone arrays. NOAA dispatched the research vessel MacArthur and they discovered a hydrothermal megaplume in the area of the seismic activity. The availability of the research vessel Wecoma in early April allows a more detailed response. The objectives of this cruise are to locate the source of the magaplume, to determine whether there has been a subsurface bacterial bloom, to determine geochemical and microbial concentrations in the plume, and, if possible, to establish patterns of crustal breakage and/or eruption.

小行星9634772 该项目是对东北太平洋戈尔达海脊热液/火山事件的快速反应。 1996年2月28日，美国国家海洋和大气管理局（NOAA）的VENTS计划通过对美国海军SOSUS水听器阵列的监测发现了一次重大地震事件。 NOAA派遣了麦克阿瑟号研究船，他们在地震活动区域发现了一个热液巨型羽流。 4月初，"韦科马"号研究船可以提供更详细的答复。 这次航行的目的是确定岩浆羽流的来源，确定地下是否有细菌大量繁殖，确定羽流中的地球化学和微生物浓度，并在可能的情况下确定地壳破裂和（或）喷发的模式。
