The EMODnet (European Marine Observation and Data network) Geology project collects and harmonizes marine geological data from the European sea areas to support decision making and sustainable marine spatial planning. The partnership includes 39 marine organizations from 30 countries. The partners, mainly from the marine departments of the geological surveys of Europe (through the Association of European Geological Surveys-EuroGeoSurveys), have assembled marine geological information at various scales from all European sea areas (e.g. the White Sea, Baltic Sea, Barents Sea, the Iberian Coast, and the Mediterranean Sea within EU waters). This dataset includes EMODnet seabed substrate maps at a scale of 1:1 500 from the European marine areas. Traditionally, European countries have conducted their marine geological surveys according to their own national standards and classified substrates on the grounds of their national classification schemes. These national classifications are harmonised into a shared EMODnet schema using Folk's sediment triangle with a hierarchy of 16, 7 and 5 substrate classes. The data describes the seabed substrate from the uppermost 30 cm of the sediment column欧洲海洋观测与数据网（European Marine Observation and Data Network，EMODnet）地质学项目，旨在收集并整合欧洲海域的海洋地质数据，为决策制定与可持续海洋空间规划提供支撑。该项目的合作网络涵盖来自30个国家的39家海洋机构，合作方主要通过欧洲地质调查协会（Association of European Geological Surveys，EuroGeoSurveys）隶属于欧洲各国地质调查局的海洋部门。上述合作方已整合了覆盖所有欧洲海域（包括白海、波罗的海、巴伦支海、伊比利亚海岸以及欧盟水域内的地中海）的多比例尺海洋地质信息。本数据集包含欧洲海域1:1500比例尺的EMODnet海底底质图。传统模式下，欧洲各国均依据本国标准开展海洋地质调查，并基于本土分类体系对底质进行分类。通过采用包含16级、7级和5级底质分类层级的Folk沉积物三角分类法（Folk's sediment triangle），这些国别分类体系被统一整合为一套通用的EMODnet标准分类方案。本数据集所描述的为沉积物柱最上层30厘米的海底底质特征。
