The OA-ICC data compilation on the biological response to ocean acidification

Numerous papers report the effects of ocean acidification on marine organisms and communities, but it is difficult to compare the results because the carbonate chemistry and ancillary data are often reported in different units and scales, and calculated using different sets of constants.

To deal with this, a compilation of data on the biological response to ocean acidification by the EU projects EUR-OCEANS and EPOCA has been resumed in the framework of the International Atomic Energy Agency (IAEA) project “Ocean Acidification International Coordination Centre (OA-ICC)”. More than 700 data sets have been archived so far. Relevant data already archived at BCO-DMO, BODC and AAD are also included in this data compilation, with links to original data sets and projects. These data are open-access at Pangaea.

Goal of the data compilation

The goal of the OA-ICC data compilation is to gather published data on the biological response to ocean acidification (carbonate chemistry, biogeochemical processes and other ancillary data) and make them available to the scientific community in a coherent format, and with a citable DOI. As part of the effort, the carbonate system variables are recalculated in a consistent way. Authors are always contacted to quality-check imported data sets before final archiving at Pangaea.

Operation and data collection process

The OA-ICC data compilation is maintained by Ms Yan Yang, Data Curator for ocean acidification data, based at the State Key Laboratory of Marine Environmental Science (Xiamen University, China), under the supervision of Dr Frédéric Gazeau, Laboratoire d’Océanographie de Villefranche, France (OA-ICC focal point for data management).

Yan extracts data directly from tables or figures in published papers, or contacts authors to collect data which is not readily available in the papers. If you are a scientist publishing on the biological response to ocean acidification, you will likely be contacted by Yan in the future. We strongly encourage you to share your data, it is a great way to get cited more (see e.g., Piwowar, 2007). If you have any concerns or questions, please contact Yan.
