Access IDP2025
The Product
The IDP2025 version consists of two parts:
(1) the digital data (hydrographic and biogeochemical data from 123 cruises, covering the global ocean) and
(2) the eGEOTRACES Electronic Atlas
(1) Access GEOTRACES digital data:
There are different ways to access GEOTRACES data:
1. Bulk (full packages) download – 3 formats: ASCII, NetCDF and Ocean Data View (ODV) collections through the DOI: 10.5285/42c92148-8d03-8be6-e063-7086abc09f0c
>>Should you need any other data format please contact the GEOTRACES IPO at [email protected]
2. Online sub-setting and extraction (WebODV Extractor online*) – easy to select variables, region, cruises, etc. Please use the webODV Explore service at: https://geotraces.webodv.awi.de/
3. Online analysis, exploration and visualization (WebODV Explore online*) – very user friendly, no need to download software or data: https://explore.webodv.awi.de/ (Please navigate to “Ocean > tracer > geotraces > idp2025”).
(2) The eGEOTRACES Electronic Atlas
The eGEOTRACES Electronic Atlas is based on the IDP digital data package and provides section plots and animated 3D scenes for many parameters, allowing quick overviews of geochemically relevant tracers. The 3D scenes provide geographical context for assessing the extent and origin of tracer plumes and inferring the processes shaping their distributions. Numerous links between tracers, sections and basins facilitate comparative studies across parameters and ocean domains. The Atlas also supports teaching, outreach, and communication of scientifically relevant results to broader audiences.
A special effort has been made to link each data value with information about the data originator, original publications, and analytical methods, ensuring proper credit to data producers.

Data Registration and Submission
The GEOTRACES Data Management Committee is pleased to announce the planned timeline for next GEOTRACES Data Products, to be released tentatively in 2028 and 2031.
Submission of your datasets requires:
- Registration of the dataset(s) via the Data for Oceanic Research (DOoR) portal:
https://geotraces-portal.sedoo.fr/pi
- Submission of your data using the GDAC data and metadata templates downloaded from DOoR to the GEOTRACES Data Assembly Center (GDAC) 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 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.
- Submission of a complete intercalibration report to the S&I Committee via the DOoR portal (a customised S&I report template 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!
- 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.
Tentative timeline:
IDP2028:
May 15, 2027 – First deadline (datasets registered in DOoR, submission of datasets to GDAC/BODC – or national data centers for US, Dutch, French and Chinese PIs – and S&I reports submitted via DOoR). After this date we cannot guarantee your data will be included in IDP2028.
Dec. 15, 2027 – Final deadline (datasets registered in DOoR, submission of datasets to GDAC/BODC – or national data centers for US, Dutch, French and Chinese PIs – and S&I reports submitted via DOoR).
Nov. 15, 2028 – IDP2028 release
IDP2031:
May 15, 2030 – First deadline (datasets registered in DOoR, submission of datasets to GDAC/BODC – or national data centers for US, Dutch, French and Chinese PIs- and S&I reports submitted via DOoR). After this date we cannot guarantee your data will be included in IDP2031.
Dec. 15, 2030 – Final deadline (datasets registered in DOoR, submission of datasets to GDAC/BODC – or national data centers for US, Dutch, French and Chinese PIs- and S&I reports submitted via DOoR).
Nov. 15, 2031 – IDP2031 release
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.
Because of the very large number of datasets that are being submitted for the IDP, we encourage submission of 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 is included in IDP” available here.

How to Ensure Your Data Are Included in the Next IDP
A flowchart describing the steps to follow to ensure that your GEOTRACES data are included in the Intermediate Data Product is now available to download.
As illustrated in the flowchart, there are three parallel pathways that must ALL be completed:
- Submission of data to the appropriate data centre
- The intercalibration process for that dataset via the Standards and Intercalibration Committee
- Permission for the data to be publicly released in the IDP
These three pathways can be completed concurrently. To help with these tasks, the GEOTRACES Data for Oceanic Research portal (DOoR) is available to register datasets for intercalibration and potential inclusion in the IDP.
Important: With IDP2021, GEOTRACES moved away from the formal registration step towards adherence to a fair use agreement, to ensure appropriate recognition of associated researchers in the subsequent usage of IDP data.
