Coastal ocean acidification and increasing total alkalinity in the northwestern Mediterranean Sea

Lydia Kapsenberg, Samir Alliouane, Frédéric Gazeau, Laure Mousseau, and Jean-Pierre Gattuso

Data sets

Seawater carbonate chemistry in the Bay of Villefranche, Point B (France), January 2007 - December 2015 J.-P. Gattuso, S. Alliouane, and L. Mousseau

Short summary
In the interest of global ocean change, weekly water samples were collected at a coastal site in the northwestern Mediterranean Sea (2007–2015). Seawater pH declined faster than expected from anthropogenic carbon dioxide increase. Total alkalinity increased, but the driver could not be identified, and it may be linked to changes in freshwater chemistry of watersheds. This is the first coastal acidification time-series providing multiyear data at high temporal resolution.
