Heavy metals - Nickel (measurements percentages)
This API provides a WMS layer showing percentage-based measurements of nickel concentrations recorded in marine organisms. It is published by the Hellenic Centre for Marine Research (HCMR) as part of the EMODnet shared geoserver infrastructure, covering Greek national waters. The dataset supports environmental monitoring of heavy metal contamination in marine biota, offering geospatial access to nickel measurement data for research, policy, and marine environmental assessment purposes.Heavy metals - Nickel (measurements percentages)
