Layer-επίπεδο: All_DDT_Measurements_Counts_Per_YearLayer: All DDT Measurements Counts Per Year
A WMS map layer published by the Hellenic Centre for Marine Research (HCMR) via GeoServer, part of the EMODnet shared data infrastructure. It provides a geospatial visualization of the counts of DDT (a persistent organic pollutant) measurements recorded per year at monitoring locations. The layer covers Greece and is intended for use in marine environmental monitoring and pollution assessment, accessible through standard WMS-compatible GIS clients.All_DDT_Measurements_Counts_Per_Year
