Aragonite saturation state dynamics in a coastal upwelling zone
Katherine E. Harris,1 Michael D. DeGrandpre,1 and Burke Hales2 — Geophys. Res. Lett., 40, doi:10.1002/grl.50460. Abstract: [1] Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (ΩAr) waters to the surface that are further suppressed by anthropogenic CO2. ΩAr was calculated with pH, pCO2, and
Acidifying oceans could spell trouble for squid
Posted on EPOCA: 03 Jun 2013 — New study reveals more acid seas could alter early development of Atlantic longfin squid Acidifying oceans could dramatically impact the world’s squid species, according to a new study led by Woods Hole Oceanographic Institution (WHOI) researchers and soon to be published in the
Direct electrolytic dissolution of silicate minerals for air CO2 mitigation and carbon-negative H2 production
Posted on EPOCA: 03 Jun 2013 We experimentally demonstrate the direct coupling of silicate mineral dissolution with saline water electrolysis and H2 production to effect significant air CO2 absorption, chemical conversion, and storage in solution. In particular, we observed as much as a 105-fold increase in OH− concentration (pH increase of up to
A short history of ocean acidification science in the 20th century: a chemist’s view
Posted on EPOCA: 30 May 2013 This review covers the development of ocean acidification science, with an emphasis on the creation of ocean chemical knowledge, through the course of the 20th century. This begins with the creation of the pH scale by Sørensen in 1909 and ends with the widespread
