Monitored Matrices Per Year
This API, published by the Hellenic Centre for Marine Research (HCMR), provides a WMS (Web Map Service) layer showing monitored environmental matrices per year. It is accessible without authentication and covers Greece at the national level. The service is part of HCMR's contribution to the EMODnet shared geoserver infrastructure, allowing users to visualize spatial data on which environmental matrices (such as water, sediment, or biota) have been monitored in a given year, supporting marine environmental monitoring and reporting activities.Monitored Matrices Per Year
