The GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of theinternational GEOTRACES programme, and contains data measured and quality controlled before the end of2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes(TEIs) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a stronglyinter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 coversthe Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons atcross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet,netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data qualityflags and 1-σ data error valueswhere available. Quality flags and error values are useful for data filtering. Metadataabout data originators, analytical methods and original publications related to the data are linked to the data in aneasily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providingsection plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data frommany cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition,the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessmentof observed tracer plumes, as well as for making inferences about controlling processes
