Microbathymetry from AUV and ROV Surveys (MOMARETO'06, MOMAR'08-Leg1 and BATHYLUCK'09 cruises) along the Lucky Strike ridge segment (Mid Atlantic Ridge)

multibeam near-bottom bathymetry from the lucky strike ridge segment along the mid-atlantic ridge. the bathymetry data were acquired during auv asterx and rov victor6000 surveys during three different cruises (momareto 2006, momar'08-leg1, & bathyluck'09). the dataset includes a central grid (luckystrike_microbathymetry_centre) that combines data from several auv and rov dives, and where original bathymetry grids for each dive have been manually shifted and combined into a single grid, using other datasets (shipboard bathymetry, acoustic sonar data from the lustre'96 data) for geographical reference. the rest of the grids are from individual rov or auv dives.all grids are provided in netcdf gmt .grd format, and with two associated geotiffs with both the bathymetry dem and the hillside (illumination) file. all grids are given in wgs84 (wgs 84 - wgs84 - epsg:4326).

本数据集包含了沿中大西洋脊幸运打击脊段的多波束近底地形数据。该地形数据是在2006年、2008年（第一航次）以及2009年（浴幸航次）的AUV Asterx和ROV Victor6000调查期间采集的。数据集包含一个中心网格（luckystrike_microbathymetry_centre），该网格整合了多次AUV和ROV潜水的数据，并通过手动调整将各次潜水原始的地形网格合并为一个单一网格，同时利用其他数据集（如船载地形数据和Lustre'96数据中的声纳数据）作为地理参照。其余网格均来自单个ROV或AUV潜水。所有网格均以NetCDF GMT .grd格式提供，并附带两个相关地理Tiff文件，分别包含地形数字高程模型（DEM）和光照（倾斜）文件。所有网格均以WGS84坐标系（EPSG:4326）给出。
