SeaDataNet is a pan-European distributed marine data infrastructure for the management, exchange and re-use of marine and oceanographic data sets. One of the objectives is to provide an overview of marine environmental research projects. This is set up as a directory that is ready for discovery, but also supporting other SeaDataNet metadata directories (e.g CDI datasets information refers to a project in EDMERP to indicate the origine of data). EDMERP covers marine research projects for a wide range of disciplines including marine meteorology; physical, chemical and biological oceanography; sedimentology; marine biology and fisheries; environmental quality; coastal and estuarine studies; marine geology and geophysics etc. Research projects are described as metadata factsheets with their most relevant aspects. The primary objective is to support users in identifying interesting research activities and in connecting them to involved research managers and organisations across Europe, which is valuable for EOSC and EOSC communities. Currently, EDMERP describes around 3.000 research projects from organisations across Europe. EDMERP offers two interfaces, a regular HTML interface for human users and a SPARQL Endpoint for machine applications.For users who want to have access to the main european-scale marine research projects active in the marine research domain.
