text: GEOTRACES Data Products are freely available [http://www.geotraces.org/dp on-line]. The third Intermediate Data Product (IDP2021) was released in November 2021. It contains hydrographical and marine geochemical data acquired during the first 10 years of the programme. The main motivation for distributing the product at this time is to strengthen and intensify collaboration with the broader ocean research community. At the same time, GEOTRACES is seeking feedback to improve future data products.
  The GEOTRACES Intermediate Data Product    consists of two parts: the digital data package and the eGEOTRACES Electronic Atlas.
  The digital data package (available at [http://www.bodc.ac.uk/geotraces/data/dp http://www.bodc.ac.uk/geotraces/data/dp]) contains data from 77 cruises and more than 800 hydrographic and geochemical parameters. The data covers the global ocean, data density being the highest in the Atlantic. 
  The eGEOTRACES Electronic Atlas (available at [http://www.egeotraces.org www.egeotraces.org]) is based on the digital data package and provides 2D and 3D images of the ocean distribution of many of the parameters. The 3D figures provide geographical context crucial for correctly assessing extent and origin of tracer plumes as well as for inferring processes acting on the tracers and shaping their distribution. The numerous links to other tracers, sections and basins found on section plots and 3D animations allow quick switching between parameters and domains and facilitate comparative studies.  In addition, eGEOTRACES can help in teaching and outreach activities and can also facilitate conveying societally relevant scientific results to interested laymen or decision makers.
