## Editorial
Copernicus Marine Service is the European Union's operational marine data and information service for ocean monitoring. It is funded through Copernicus and implemented by Mercator Ocean International through a pan-European production and service network, so buyers should treat it as a public service/distribution network rather than a commercial company.[^copernicus-marine-eu][^mercator-what-we-do] The service provides free and open marine products through Copernicus Marine Data Store, including physical ocean, sea-ice, and biogeochemical information for global and regional seas.[^cmems-data-store][^cmems-service-commitments] Access routes include subset delivery for chosen variables, areas, times, and depths, original producer files, and map services for browser or GIS visualisation.[^cmems-download-help] The Copernicus Marine Toolbox adds CLI and Python API access for metadata, subsetting, and original-file retrieval, including NetCDF, Zarr, and selected GeoTIFF or Shapefile workflows.[^cmems-toolbox-docs] Product latency, formats, accuracy, and service availability vary by product and access route, so procurement and integration checks should be done at product level rather than at service-brand level.[^cmems-data-store][^cmems-download-help]
