description: >-
  The EU Copernicus Marine Environment Monitoring Service (CMEMS), operated by
  Mercator Ocean International, provides free and open access to authoritative
  information on the state of the global ocean and European regional seas. The
  service delivers ocean physical and biogeochemical data through multiple APIs
  covering temperature, salinity, sea level, currents, sea ice, and marine
  ecosystem variables from satellite observations, in situ measurements, and
  numerical model reanalysis and forecast products. Data can be accessed
  programmatically via the Copernicus Marine Toolbox (Python API and CLI), the
  OGC-compliant Web Map Tile Service (WMTS) for visualization, and the
  Catalogue Service for the Web (CSW) for product discovery. All services
  require a free Copernicus Marine account, except the CSW which is fully open,
  and there are no data volume quotas or download limits.

  - name: Copernicus Marine Toolbox API
    description: >-
      The Copernicus Marine Toolbox provides the officially supported
      programmatic interface to the Copernicus Marine Data Store, available as
      both a Python library and CLI. Core operations include describe (browse
      the full product catalogue and retrieve dataset metadata), subset (extract
      data by variable, geographic bounding box, time range, and depth range in
      NetCDF, Zarr, CSV, or Parquet formats), get (download original production
      files with wildcard and regex filtering), open_dataset (lazy-load datasets
      remotely via xarray), and read_dataframe (load data directly into pandas).
      The service offers no quota on data volume or bandwidth. Authentication
      uses username and password stored in a credentials file or environment
      variables COPERNICUSMARINE_SERVICE_USERNAME and
      COPERNICUSMARINE_SERVICE_PASSWORD. A free Copernicus Marine account is
      required.

  - name: Copernicus Marine WMTS API
    description: >-
      The Copernicus Marine Web Map Tile Service (WMTS) is an OGC-compliant
      REST API for visualizing ocean data as raster map tiles. It supports
      GetCapabilities to discover available datasets and layers, GetTile to
      retrieve cached image tiles in JPEG or PNG format, GetLegend to obtain
      dynamic map legends in SVG or JSON, and GetFeatureInfo to query pixel-level
      data values at specific geographic locations. Tiles are served in Web
      Mercator (EPSG:3857), WGS 84 (EPSG:4326), and polar projections. Temporal
      and depth dimensions are supported via TIME and ELEVATION parameters.
      The service is fully OGC WMTS 1.0.0 compliant and INSPIRE conformant. No
      authentication is required for tile access.

  - name: Copernicus Marine CSW Catalogue API
    description: >-
      The Copernicus Marine Catalogue Service for the Web (CSW) provides
      OGC-compliant metadata discovery over the full product catalogue. It
      supports GetCapabilities, DescribeRecord, GetRecords (search and filter
      catalogue entries), and GetRecordById (retrieve a specific product record
      by identifier). The service is based on CSW 2.0.2 and uses ISO 19115
      metadata records. No authentication or Copernicus Marine account is
      required, and there are no documented rate limits or quotas for the
      catalogue service.
