Processed Near-bottom Bathymetry Data (ASCII format) derived from Scanning Altimetric Sonar Data from the East Pacific Rise at 9N acquired with HOV Alvin during Atlantis expedition AT15-14 (2006)

This data set was acquired with an Imagenex 881 Scanning Sonar on the HOV Alvin during Atlantis expedition AT15-14 conducted in 2006 (Chief Scientist: Dr. James Ledwell). These data files are of Text (ASCII) format and include Bathymetry data that were merged with navigation and processed after data acquisition. Data were acquired as part of the project(s): Larval Dispersal Along the Deep East Pacific Rise (LADDER-2), Collaborative Research: Oceanographic and Topographic Influences on Dispersal of Hydrothermal Vent Species, Development and colonization processes in Alvinella pompejana, Hydrothermal Vent Meiobenthos, Potential of hydrothermal plumes as a source of dissolved iron (Fe) to the deep ocean and a sink of dissolved organic carbon (DOC), Chemical Characterizations of Vent Habitats, Development, Growth and Cell Kinetic Studies in Riftia Pachyptila, and Preliminary Deployment of Magnetic Collectors for Examination of Vent Particle Dispersal, and funding was provided by NSF grant(s): OCE04-24953.

本数据集由搭载于“阿尔文号”载人深潜器（HOV Alvin）的Imagenex 881型扫描声呐（Imagenex 881 Scanning Sonar）采集，采集工作开展于2006年执行的亚特兰蒂斯号科考航次AT15-14，首席科学家为詹姆斯·莱德韦尔（James Ledwell）博士。本次数据文件采用文本（ASCII）格式，包含经导航数据融合、采集后处理得到的水深地形（Bathymetry）数据。本数据采集隶属于以下多项研究项目：东太平洋深水区幼体扩散研究（Larval Dispersal Along the Deep East Pacific Rise，缩写LADDER-2）、热液喷口物种扩散的海洋学与地形影响合作研究、阿尔文虫（Alvinella pompejana）的发育与定殖过程研究、热液喷口小型底栖生物研究、热液羽流作为深海溶解态铁（Fe）源与溶解有机碳（DOC）汇的潜力研究、喷口生境化学特征研究、巨管虫（Riftia pachyptila）的发育、生长与细胞动力学研究，以及用于检测喷口颗粒扩散的磁性收集器初步部署研究。本研究获得美国国家科学基金会（National Science Foundation, NSF）项目OCE04-24953资助。
