Historical TEI Data

Links to relevant historical data sets collected outside of the GEOTRACES programme.  This data has, in general, not been quality-controlled or intercalibrated according to GEOTRACES protocols and is typically compiled from literature sources.  These links are provided as a service to the community; the compilations are not a formal part of the GEOTRACES programme.


The GEOSECS data collection contains hydrographic and tracer data from the GEOSECS program as released by the Scripps Institution of Oceanography on February 5th 1986. This data has been reformatted and quality controlled for use with the Ocean Data View software (ODV) by Reiner Schlitzer, Alfred Wegener Institute, Bremerhaven, Germany using the original GEOSECS data files provided by Bob Key, Princeton University.

Iron synthesis

The Iron synthesis programme involved a data recovery effort aimed at assembling a common, open-access database of data and metadata from a series of in-situ ocean iron fertilisation experiments conducted between 1993 and 2005. This database is maintained and run by the staff of Biological and Chemical Oceanography Data Management Office (BCO-DMO)
