Environmental conditions measured at colonization surfaces or on seafloor.

Measurements recorded at 9, 11, 22 or 23 months after the eruption, during cruises in October 2006, December 2006, and November/December 2007 respectively, and pre-eruption (Pre) in December 1995. Sites were vents in the region of 9°50′N East Pacific Rise (Fig. 1), habitats were characterized as hot (H), warm (W) or cool (C) on initial visit. Temperature (T) was measured directly at colonization surfaces with Alvin probe. Temperature, pH and free sulfide (sul) were measured at the seafloor with electrochemical sensors in the vicinity of colonization surfaces and at other nearby vents (N = number of measurements in each habitat type).本数据集的测量数据分别采集于火山喷发后9、11、22、23个月，对应2006年10月、2006年12月、2007年11/12月的科考航次，以及1995年12月的喷发前（Pre）阶段。采样点位位于东太平洋海隆（East Pacific Rise）9°50′N区域的热液喷口（图1）；初始调查时将生境划分为高温（H）、暖温（W）与低温（C）三类。温度（T）通过阿尔文（Alvin）探针直接在定植表面测得；研究人员借助电化学传感器，在定植表面附近及其他邻近喷口的海底环境中，测定了温度、pH值与游离硫化物（free sulfide），其中N为每类生境的有效测量次数。
