REMINDER: GEOTRACES IDP2028 — First deadline: 15 May 2027

NewItem News

2 October 2026

This is a kind reminder that the first deadline for the GEOTRACES Intermediate Data Product (IDP) 2028 is 15 May 2027! Please see the IDP timeline at the bottom of this email.

Because of the very large number of datasets being submitted for the IDP, we encourage you to submit your datasets as soon as possible to improve the chances that they are included in the IDP. Please see the flowchart, “How to ensure that your data are included in the IDP,” available here.

Processing of data for inclusion for each IDP will prioritise those submitted before the May deadline and then will prioritise section cruises over process studies over compliant data. 

There are a large number of datasets requiring intercalibration registered in the Data for Oceanic Research (DOoR) portal for which an intercalibration report has not been submitted. We remind you that, if no intercalibration report is submitted, these datasets cannot be included in the IDP, as described below:

Submission of your datasets requires:

  1. Registration of the dataset(s) via the Data for Oceanic Research (DOoR) portal:
    https://geotraces-portal.sedoo.fr/pi
  2. Submission of your data using the GDAC data and metadata template downloaded from DOoR to the GEOTRACES Data Assembly Center (GDAC, via the BODC portal: https://submit-data.bodc.ac.uk/) or your national data centre for Chinese, Dutch, French and USA scientists*.
    • We very strongly recommend that you use the data template that is offered by GDAC in the DOoR portal to report your data to GDAC or the appropriate data centre.
    • *USA scientists: To increase the efficiency of processing your data, we also strongly recommend that you send your data directly to GDAC in addition to BCO-DMO.
  3. Submission of a complete intercalibration report to the S&I Committee via the DOoR portal (a customised S&I report template created by the S&I Committee can be downloaded from DOoR).
    • An example of a complete report is available here (please note that if the report is not fully completed will not fulfil the requirement).
    • We strongly recommend that you submit your S&I reports as soon as possible so that they can be reviewed in time by the S&I!
  4. Give permission for your data to be included in IDP via the DOoR Portal. If permission is not given your data will not be included in the IDP.
