Macrofauna collected on colonization surfaces at the East Pacific Rise 9 50 N hydrothermal vent field in 1998-2017

This dataset includes an occurrence table for macrofauna collected on colonization surfaces at the East Pacific Rise 9 50 N hydrothermal vent field in 1998-2017. The colonization surfaces were recovered before or after an eruption in January 2006, with pre-eruption blocks at East Wall and post-eruption sandwiches at P Vent. Samples were preserved in ethanol and examined under a dissecting microscope, and species and morphogroups were matched to equal or lowest level taxon in the World Register of Marine Species (WoRMS). The extended measurement or facts table specifies the number of months since eruption, deployment habitat zone (H=Hot, W=Warm, C=Cool), and recovery temperature (deg C) for each sample. This dataset derives from counts of colonists reported by Mullineaux (2020, DOI:10.26008/1912/bco-dmo.733173.2) for sampling events and cruises listed by Mullineaux (2020, DOI:10.26008/1912/bco-dmo.733210.3). Funding to standardize these data to Darwin Core for sharing through the Ocean Biodiversity Information System was from NSF DEB-1558904 and NSF OCE-1829773. This dataset provides 3536 machine-readable counts of macrofauna at a hydrothermal vent field located in the area beyond national jurisdiction.本数据集包含1998-2017年间于东太平洋海隆9°50′N热液喷口区的定植基质上采集的大型宏动物（macrofauna）出现数据表。这些定植基质于2006年1月火山喷发前后被回收，其中东壁（East Wall）区域的为喷发前岩块，P喷口（P Vent）区域的为喷发后三明治状基质。所有样本以乙醇保存，随后在体视显微镜下进行检视，并将物种及形态类群匹配至《世界海洋物种登记册（World Register of Marine Species, WoRMS）》中的对应或最低阶分类单元。扩展测量数据表列明了各样本距火山喷发的月数、布设生境带（H=高温区、W=温水区、C=低温区）以及回收时的温度（单位：摄氏度）。本数据集的数据源自Mullineaux（2020，DOI:10.26008/1912/bco-dmo.733173.2）所报告的定植生物计数结果，对应采样活动与航次信息详见Mullineaux（2020，DOI:10.26008/1912/bco-dmo.733210.3）。将本数据集标准化为达尔文核心（Darwin Core）格式并通过海洋生物多样性信息系统共享的资助项目来自美国国家科学基金会（NSF）的DEB-1558904与OCE-1829773两项经费。本数据集共提供了位于国家管辖范围以外区域的一处热液喷口区的3536条大型宏动物机器可读计数数据。
