Quaternary – age This web map service shows the chronostratigraphic age of geological units of the seafloor originated in the Quaternary period (i.e. 2,588 Ma from now until today). The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project phases II and III between 2009 and 2021. The scale varies between 20 000 and 2 500 000.第四纪（Quaternary）年代网络地图服务 本网络地图服务展示了形成于第四纪时期（即距今258.8万年前至现今）的海底地质单元的年代地层年龄。该数据集由BGR于2009年至2021年间，从EMODnet地质项目第二、第三阶段的合作机构处汇编而成。本地图的比例尺范围为20000至2500000。
