DSV Alvin composite scanning sonar bathymetry grids from East Pacific Rise (EPR) 9°50N

This data set includes 0.5 m resolution gridded bathymetry data that were acquired with an Imagenex 881 Scanning Sonar on the HOV Alvin during multiple dives and expeditions. Data were acquired in 2004: AT-11-07, AT-11-10, AT-11-13, AT-11-20 and 2005: AT-11-26. Data were assembled and integrated as part of the 2006 EPR_9N_Ferrini data compilation (Lead Scientist: Dr. Vicki Ferrini). This data set includes gridded bathymetry data files are of NetCDF Grid format and MATLAB binary files that contain XYZ points as well as gridded data. These data were described by Ferrini et al., 2007.

本数据集包含0.5米分辨率的网格化水深地形数据，此类数据由搭载于载人深潜器阿尔文号（HOV Alvin）的Imagenex 881型扫描声呐，于多次下潜考察任务中采集获取。数据采集工作分别开展于2004年的AT-11-07、AT-11-10、AT-11-13、AT-11-20航次，以及2005年的AT-11-26航次。本数据集作为2006年EPR_9N_Ferrini数据汇编项目的组成部分完成整合与集成，该项目的首席科学家为维基·费里尼博士。数据集包含NetCDF网格格式与MATLAB二进制格式的水深地形数据文件，两种格式的文件均存储有XYZ点坐标数据与网格化地形数据。相关数据的详细说明已发表于Ferrini等人2007年的学术成果中。
