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 2019 as a single archive.

背景概述

Global Marine Environment Dataset (GMED) 是一个包含公开可用的气候、生物和地球物理环境层的全球海洋环境数据集，涵盖从表层到海洋最深处的各种环境条件。该数据集具有统一的空间范围、高分辨率陆地掩膜和高空间分辨率（5弧分钟，约9.2公里近赤道），可用于快速绘制物种分布图。数据集由新西兰政府资助，采用CC BY 4.0许可证。
