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.

NSF RIDGE 2000计划于2007年1月在东太平洋洋脊（EPR）上赞助了快速反应巡航。 SGER包括调查员参加巡航的工资费用。 调查员进行的研究显然具有时间敏感性，并在了解热液喷口微生物群落方面探索了变革性科学。 研究人员声称，自养细菌是热液喷口的第一批定居者，随着时间的推移，异养微生物的数量不断增加。 参加快速反应巡航使调查员有机会进行必要的取样，以检验这一假设。 巡航后的分析包括从泵过滤器中提取核酸和脂质，以及确定定居在玄武岩中的微生物的种类。
