Processed Gridded Near-bottom Scanning Sonar Data (version 1) from the East Pacific Rise acquired during the Atlantis expedition AT11-20 (2004)

This data set was acquired with a Imagenex 881 Scanning Sonar on the HOV Alvin during Atlantis expedition AT11-20 conducted in 2004 (Chief Scientist: Dr. Marvin Lilley; Investigator(s): Dr. Vicki Ferrini). These data files are of ASCII:ESRI format and include gridded Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Biocomplexity: Smart Sensors for In Situ Monitoring of Hydrothermal Vent Systems, Establishing a Role for Fe and S Microbial Metabolism in Ocean Crust Weathering, Time-Series Larval Studies in the Deep Sea, and The Interaction of Microbial Biofilms and Fluid Chemistry on Larval Settlement, and funding was provided by NSF grant(s): OCE01-19999, OCE02-41791, and DOEI. This data was cited by Ferrini et al., 2007.

本数据集由搭载于载人深潜器阿尔文号（HOV Alvin）的Imagenex 881型扫描声呐采集，采集工作于2004年开展的亚特兰蒂斯号航次AT11-20期间完成，本次航次首席科学家为Marvin Lilley博士，参与研究人员包括Vicki Ferrini博士。本数据集文件采用ASCII:ESRI格式，包含网格化水深地形（Bathymetry）数据，且在数据采集完成后经过了后处理。本数据的采集隶属于以下四项研究项目：热液喷口系统原位监测智能传感器相关生物复杂性研究、确立铁与硫微生物代谢在洋壳风化中的作用、深海浮游幼虫长期序列研究、微生物生物膜与流体化学对幼虫附着的调控作用。本研究获得美国国家科学基金会（National Science Foundation, NSF）OCE01-19999、OCE02-41791两项资助以及美国能源部（Department of Energy, DOE）资助项目I的支持。本数据集已被Ferrini等人于2007年引用。
