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. type: Index image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg url: https://raw.githubusercontent.com/api-evangelist/copernicus-marine/refs/heads/main/apis.yml created: '2026-06-13' modified: '2026-06-13' specificationVersion: '0.19' tags: - Ocean - Marine - Oceanography - Sea Level - Temperature - Salinity - Currents - Biogeochemistry - Climate - Environment - Satellite - Forecast - Reanalysis - Open Data - EU apis: - 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. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://toolbox-docs.marine.copernicus.eu/ baseURL: https://data.marine.copernicus.eu tags: - Ocean Data - Subsetting - NetCDF - Zarr - Python - CLI - Download properties: - type: Documentation url: https://toolbox-docs.marine.copernicus.eu/ - type: HelpCenter url: https://help.marine.copernicus.eu/en/collections/9080063-copernicus-marine-toolbox - type: GitHubRepository url: https://github.com/mercator-ocean/copernicus-marine-toolbox - type: PyPI url: https://pypi.org/project/copernicusmarine/ - type: Registration url: https://data.marine.copernicus.eu/register - 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. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://help.marine.copernicus.eu/en/articles/6478168-how-to-use-wmts-to-visualize-data baseURL: https://wmts.marine.copernicus.eu/teroWmts tags: - WMTS - OGC - Map Tiles - Visualization - Raster - Web Mapping properties: - type: Documentation url: https://help.marine.copernicus.eu/en/articles/6478168-how-to-use-wmts-to-visualize-data - type: GetCapabilities url: https://wmts.marine.copernicus.eu/teroWmts?service=WMTS&version=1.0.0&request=GetCapabilities - 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. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://help.marine.copernicus.eu/en/articles/6643157-how-to-access-to-metadata-using-the-catalogue-service-on-the-web-csw baseURL: https://csw.marine.copernicus.eu/geonetwork/csw-MYOCEAN-CORE-PRODUCTS/eng/csw tags: - CSW - OGC - Catalogue - Metadata - Discovery - INSPIRE properties: - type: Documentation url: https://help.marine.copernicus.eu/en/articles/6643157-how-to-access-to-metadata-using-the-catalogue-service-on-the-web-csw - type: GetCapabilities url: https://csw.marine.copernicus.eu/geonetwork/csw-MYOCEAN-CORE-PRODUCTS/eng/csw?service=CSW&REQUEST=GetCapabilities common: - type: DomainSecurity url: security/copernicus-marine-domain-security.yml - type: Website url: https://marine.copernicus.eu/ - type: Documentation url: https://help.marine.copernicus.eu/ - type: DataStore url: https://data.marine.copernicus.eu/products - type: Registration url: https://data.marine.copernicus.eu/register - type: GitHubOrg url: https://github.com/mercator-ocean - type: LinkedIn url: https://www.linkedin.com/company/copernicus-marine-service - type: Blog url: https://marine.copernicus.eu/news - type: Pricing url: https://marine.copernicus.eu/access-data/ - type: Plans url: plans/copernicus-marine-plans.yml - type: RateLimits url: rate-limits/copernicus-marine-rate-limits.yml - type: FinOps url: finops/copernicus-marine-finops.yml maintainers: - FN: Kin Lane email: kin@apievangelist.com
