Tracking ocean acidification from in situ measurements in the North Atlantic over the last three decades (1981-2008)
Poster.-- SOLAS Open Science Conference, Barcelona, 16-19 November 2009 A dataset of direct pH measurements comprising twelve cruises and spanning three decades has revealed a progressive acidification in the Iberian, Iceland and Irminger basins. Generally, the maximum pH drop occurs in the upper la...
