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.

本数据集由搭载于载人深潜器阿尔文号（HOV Alvin）的Imagenex 881扫描声呐采集，采集工作于2006年执行的亚特兰蒂斯号科考航次AT15-14期间完成，首席科学家为詹姆斯·莱德维尔（James Ledwell）博士。本数据集包含的文件均为文本（ASCII）格式，收录了与导航数据融合后的水深测量（Bathymetry）数据，且所有数据均在采集完成后完成预处理与整合。本数据隶属于以下多项研究项目：东太平洋海隆深层幼虫扩散研究（Larval Dispersal Along the Deep East Pacific Rise，LADDER-2）、合作研究项目：大洋环流与地形对热液喷口物种扩散的影响、阿尔文蛰龙介（Alvinella pompejana）的发育与定殖过程、热液喷口小型底栖生物研究、热液羽流作为深海溶解铁（Fe）源与溶解有机碳（DOC）汇的潜力评估、喷口生境化学特征研究、巨型管虫（Riftia pachyptila）的发育、生长及细胞动力学研究，以及用于考察喷口颗粒物扩散的磁性收集器初步部署项目。本研究获得美国国家科学基金会（NSF）项目OCE04-24953资助。
