Layer-επίπεδο: Benzo_a_pyrene_Measurements_Counts_Per_YearLayer: Benzo[a]pyrene Measurements Counts Per Year
This is a WMS map layer published by the Hellenic Centre for Marine Research (HCMR) as part of the EMODnet shared geoserver services. It provides a geospatial representation of the yearly counts of benzo[a]pyrene measurements, a polycyclic aromatic hydrocarbon monitored for marine and environmental quality purposes in Greece. The layer supports visualization and spatial analysis of monitoring effort and sampling frequency over time, and can be accessed freely without authentication through standard WMS clients or GIS software.Benzo_a_pyrene_Measurements_Counts_Per_Year
