EPOCA/EUR-OCEANS data compilation on the biological and biogeochemical responses to ocean acidification

摘要

The uptake of anthropogenic CO2 by the oceans has led to a rise in the oceanic partial pressure ofCO2, and to a decrease in pH and carbonate ion concentration. This modification of the marine carbonate system is referred to as ocean acidification. Numerous papers report the effects of ocean acidification on marineorganisms and communities but few have provided details concerning full carbonate chemistry and complementary observations. Additionally, carbonate system variables are often reported in different units, calculatedusing different sets of dissociation constants and on different pH scales. Hence the direct comparison of experimental results has been problematic and often misleading. The need was identified to (1) gather data oncarbonate chemistry, biological and biogeochemical properties, and other ancillary data from published experimental data, (2) transform the information into common framework, and (3) make data freely available. Thepresent paper is the outcome of an effort to integrate ocean carbonate chemistry data from the literature whichhas been supported by the European Network of Excellence for Ocean Ecosystems Analysis (EUR-OCEANS)and the European Project on Ocean Acidification (EPOCA). A total of 185 papers were identified, 100 contained enough information to readily compute carbonate chemistry variables, and 81 data sets were archivedat PANGAEA – The Publishing Network for Geoscientific & Environmental Data. This data compilation isregularly updated as an ongoing mission of EPOCA.Data access: http://doi.pangaea.de/10.1594/PANGAEA.735138
