ocean model bathymetry on eORCA12 grid derived from GEBCO2021

Ocean model bathymetry on the eORCA12 grid (nominal 1/12 degree horizontal resolution), derived from the GEBCO2021 dataset. Also included is a file containing the grid and land-sea mask information required to reproduce the bathymetry. Details of the process used to derive the bathymetry are here: https://github.com/JMMP-Group/GLOBAL_BATHYMETRY本数据集为基于eORCA12网格（标称水平分辨率为1/12度）的海洋水深地形（bathymetry）模型，其源自GEBCO2021数据集。本数据集同时包含用于复现该水深地形所需的网格与海陆掩模（land-sea mask）信息文件。有关该水深地形提取流程的详细说明，请参见： https://github.com/JMMP-Group/GLOBAL_BATHYMETRY
