The number of studies investigating the effects of ocean acidification on marine organisms and communities are increasing every year. Results are not easily comparable since the carbonate chemistry and ancillary data are not always reported in similar units and scales, and calculated using similar sets of constants.

In response to this problem, a data compilation is hosted at PANGAEA Data Publisher for Earth and Environmental Science and maintained in the framework of the International Atomic Energy Agency (IAEA) project “Ocean Acidification International Coordination Centre (OA-ICC)” in collaboration with Xiamen University. The goal of this data compilation is to ensure the archival and streamlining of data on the biological response to ocean acidification (and other environmental drivers), as well as to provide easy access to the data for all users. Published data are made available to the scientific community in a coherent format and with a citable DOI.

Our team extracts data directly from tables or figures in published papers, or downloads the data from other data repositories such as the Biological and Chemical Oceanography Data Management Office (BCO-DMO), the British Oceanographic Data Centre (BODC) and the Australian Antarctic Data Centre (AADC). Finally, we are contacting authors to collect data which are not readily available in the papers or other data repositories.
As part of the effort, the carbonate system variables are recalculated in a consistent way. Authors are always contacted to quality-check their data sets before archiving.

The compilation currently includes data from over 1000 data sets from more than 900 papers.

The list of papers currently included in the database can be consulted from the "Included/not included papers" page.

If any of your published data are not currently included in the database, please do not hesitate to contact us. The OA-ICC thanks you in advance for sharing your data, it is a great way to get more cited!
