What is GEOTRACES Intermediate Data Product?
The GEOTRACES Intermediate Product provides extensive hydrographic and marine geochemical data collected from multiple research cruises across all ocean basins. It is composed of two main components: (1) a digital data package and (2) an eGEOTRACES Atlas that allows visualisation though section plots and animated 3D scenes of many of the parameters. In addition, a webODV tool allows analysis, exploration and visualisation of these data.
