Facilitate and promote intercomparison of key measured and derived ocean acidification variables to support development of a rigorous unified global data set.
Support international intercomparions exercises
Key measurements and indices of ocean acidification are made by different investigators with different techniques. To understand acidification at the global scale, these measurements from different sources must be made consistent and combined into a single global database. In addition, because ocean acidification research is in its infancy there is a clear and increasing need to standardize experimental protocols, such as those used to conduct perturbation experiments in mesocosms. These issues were highlighted in the Guide to Best Practices in Ocean Acidification Research and Data Reporting published in 2010 but more effort is needed to build on this original investment. Hence the OA-ICC supports a number of related intercomparison exercises:
- Compare software packages that compute carbonate chemistry (in cooperation with the International Ocean Carbon Coordination Project)
- Compare techniques to measure calcification (in planning)
- Compare boron isotope measurements, a technique to assess past pH, across labs with shared carbonate samples (in planning)
