GEOTRACES Intermediate Data Product 2021 (Version 1)

The GEOTRACES Intermediate Data Product 2021 (IDP2021) is released on 17 November 2021. The IDP2021 represents a major new data release. Compared to IDP2017, IDP2021 improves data coverage significantly in all ocean basins, especially in the Arctic, the Indian and the Pacific Oceans. Overall, the new data product contains more than twice the number of cruises, stations and actual data values.

IDP2021 is, open access data sets, licensed under a Creative Commons Attribution 4.0 International license. Please, read the Fair Data Use Statement for GEOTRACES IDP2021GEOTRACES IDP2017 version 2 changes before using IDP2021.

The original versions of the IDP2021 digital datasets can be accessed from the links below - please use the current version of the digital datasets for any current research.

The GEOTRACES IDP2021 consists of two parts:

  1. the digital datasets — available for download below or as a subset via the online service hosted by the Alfred Wegener Institute (AWI).
  2. the eGEOTRACES Electronic Atlas — is based on the digital data package and provides section plots (as illustrated below) and animated 3D scenes for many of the parameters. The 3D scenes provide geographical context, which is crucial for correctly assessing extent and origin of tracer plumes as well as for inferring processes acting on the tracers and shaping their distribution.

IDP2021 digital datasets (original version)

The IDP2021 digital datasets are made available to download here by the GEOTRACES International Data Assembly Centre hosted by the British Oceanographic Data Centre (BODC). They are provided in 3 data formats: ASCII, NetCDF and ODV collections. The latter is for use with the Ocean Data View software.

If the data sets are used in a presentation or publication then we ask that you acknowledge the source.This should be of the form: GEOTRACES Intermediate Data Product Group (2021).
