Ocean acidification refers to an ongoing change in the chemistry of the ocean caused an increase in the uptake of carbon dioxide from the atmosphere. 

The ocean absorbs about one third of human-created carbon dioxide emissions. Carbon dioxide is a ‘Greenhouse Gas’ produced by the burning of fossil fuels. When carbon dioxide dissolves in seawater, carbonic acid is produced. This is slowly increasing the acidity of the oceans which can have a range of harmful consequences, such as depressing metabolic rates and immune responses in some organisms, causing coral bleaching and affecting the ability of some organisms to build the calcium carbonate shells that protect them. These changes pose new risks for a vast range of ocean life, from clams and coral reefs to crabs, shrimp, lobster, krill, sea urchin, sea snails, and some kinds of plankton, to name a few.

About the Project

Sea Change is an EU H2020 funded project that aims to establish a fundamental “Sea Change” in the way European citizens view their relationship with the sea, by empowering them, as Ocean Literate citizens, to take direct and sustainable action towards a healthy ocean, healthy communities and ultimately a healthy planet.

The Sea Change consortium consists of 17 partners from nine different countries, coordinated by the Marine Biological Association of the United Kingdom.

This consortium, which comprises nine public research organisations, one SME, five non profit organisations and two higher education institutions, brings together selected experts to collectively provide the knowledge, competence, skills and facilities needed for ensuring a good project development, the achievement of project objectives and the successful delivery of project results.
