Global Marine Environment Dataset (GMED)

The Global Marine Environment Datasets (GMED) is a compilation of publicly available climatic, biological and geophysical environmental layers featuring present, past and future environmental conditions. GMED covers the widest available range of environmental layers from a variety of sources and depths from the surface to the deepest part of the ocean. It has a uniform spatial extent, high-resolution land mask (to eliminate land areas in the marine regions), and high spatial resolution (5 arc-minute, c. 9.2 km near equator). The free online availability of GMED enables rapid map overlay of species of interest (e.g. endangered or invasive) against different environmental conditions of the past, present and the future, and expedites mapping distribution ranges of species using popular SDM algorithms. This archive features a snapshot of GMED dataset in 2018 as a single archive which is associated with the Earth Systems Data Science Manuscript.

全球海洋环境数据集（Global Marine Environment Datasets，GMED）是一套整合多源公开气候、生物与地球物理环境图层的数据集，涵盖当前、过往及未来的海洋环境状况。GMED收录了来源多样的环境图层，覆盖范围最为广泛，深度维度涵盖从海洋表层直至深海最深处的全部区间。该数据集具备统一的空间覆盖范围，搭载高分辨率陆地区域掩码（用于剔除海洋区域内的陆地区域），空间分辨率可达5弧分，在赤道附近约合9.2公里。GMED的免费在线获取权限，支持研究人员快速将目标物种（如濒危物种或入侵物种）的分布与过往、当前及未来的各类海洋环境条件进行图层叠加分析，并可借助主流的物种分布模型（Species Distribution Model，SDM）算法，加速物种分布范围的制图工作。本归档文件包含2018年版GMED数据集的快照，为单一归档包，且与《地球系统数据科学》研究论文相关联。
