  3. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Context / Motivation • Numerous papers have report on the effects of ocean acidification on marine organisms and communities. However, few papers have offered details concerning carbonate chemistry and other ancillary data. • When details on carbonate chemistry are given: The carbonate system parameters are often reported on different pH scales (NBS, total, free or seawater) using different sets of equilibrium constants. • Different units + Different sets of constants + Different pH scales • Data comparison : difficult !!

  4. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Objectives • To gather data on the carbonate chemistry, biogeochemical processes, and other ancillary data that has been already published. • (2) To analyze and transform the metadata collected. (3) To make them available to the whole community via the EUR-OCEANS network database. 24 K € in Salary Started early January 2008 and run for 7 months duration

  5. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Parameters to beCompiled • Metadata: Methods, Units, Constants, Scales, Time, date, depth, longitude, latitude…etc. • Core Parameters: Parameters of the carbonate chemistry (pH, pCO2, DIC, and/or TA…etc) and Salinity, temperature. • Ancillary Parameters: Photosynthesis, respiration, calcification, growth, abundance, irradiance, nutrients (N, Si, P)…etc This is not an exhaustive list ; it is continuously extended

  6. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Exemple of Parameters

  7. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Data sets sends format

  8. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Data sets compiled format

  9. EUROCEANS Data Transformation Project : Biological and biogeochemical responses to ocean acidification Don’tWorry Even if data are treated and transformed to common units The original data are still well identified The final product will be submitted to PANGAEA data base, WDC-MARE
