The objective of the European Free Ocean Carbon dioxide Enrichment Experiment (eFOCE) is to develop, validate and implement experimental systems that enable scientists to investigate the long-term effects of acidification in situ on benthic marine communities – i.e. those organisms which live on or near the seabed. The project will be carried out in cooperation with MBARI and in partnership with several European laboratories involved in two projects, EPOCA and MedSeA, being co-funded by the European Commission. Over a 3-year period, the aim of the project is to develop and test systems which can be used in relatively long (> 6 month) experiments in the Mediterranean Sea. The ultimate goal is to increase the number of these systems and make them available to the international scientific community via an international network. Visit the eFOCE web site.
