The NSF RIDGE2000 program sponsored Rapid Response cruise in January 2007 on the East Pacific Ridge (EPR). The SGER covers salary expenses for the investigator's participation in the cruise. The research conducted by the investigator is obviously time sensitive and ventures into transformative science in understanding microbial communities at hydrothermal vents. The investigator asserts that autotrophic bacteria are the first colonizers at hydrothermal vents, followed by increasing numbers of heterotrophic microorganisms over time. Participation in the rapid response cruise allowed the investigator the opportunity to conduct the necessary sampling to test this hypothesis. Analyses following the cruise include extraction of nucleic acids and lipids from the pump filters as well as determine the kind of microbes that have colonized the basalt.

2007年1月，美国国家科学基金会RIDGE2000项目在东太平洋海岭（EPR）发起了快速反应巡航。SGER承担调查员参加邮轮的工资费用。研究者进行的研究显然是时间敏感的，并且在了解热液喷口的微生物群落方面冒险进入变革科学。研究者断言自养细菌是热液喷口的第一批殖民者，其次是随着时间的推移而增加的异养微生物数量。参与快速反应巡航使研究者有机会进行必要的抽样来检验这一假设。巡航后的分析包括从泵过滤器中提取核酸和脂质，以及确定在玄武岩上定居的微生物种类。
