The European Mediterranean Sea Acidification in a changing climate (MedSeA) initiative was a project funded by the European Commission under Framework Program 7 (2011-2014).  It involved 22 institutions (including 6 associated partners) from 12 countries.

MedSeA assesses uncertainties, risks and thresholds related to Mediterranean acidification at organismal, ecosystem and economical scales. It also emphasizes conveying the acquired scientific knowledge to a wider audience of reference users, while suggesting policy measures for adaptation and mitigation that will vary from one region to another.
