Data & products on marine water quality

How does the viewer work

EMODnet Chemistry provides an interoperable on-line viewing service (Ocean Browser) for the visualization of the products developed with the harvested chemical data and for products available from the other thematic portals


OceanBrowser is a web-service that allows users to visualize gridded fields on-line. It is based on open standards from the Open Geospatial Consortium (OGC), in particular Web Map Service (WMS) and Web Feature Service (WFS). These standards define a protocol for describing, requesting and querying two-dimensional maps at a given depth and time. OceanBrowser currently supports the following operations:

  • Visualization at a selected depth and time of the horizontal sections of the 4-dimensional fields (longitude, latitude, depth and time).
  • Interpolation and visualisation of the climatological fields on arbitrary vertical sections defined by users.
  • Animation of the horizontal and vertical sections in order to study the evolution in time.
  • Image export in several formats: raster (PNG) or vector (SVG, EPS, PDF). It can also be saved as a KML file (so that the current layer can be visualized in programs like Google Earth).
  • Download of the underlying 4-dimensional netCDF file, either as a whole from the interface or only as a subset using the linked OPeNDAP server.
  • Import of third-party layers by using standard WMS requests. The user needs only to specify the URL of the WMS server and its supported version.
