The intensity, duration, and severity of low aragonite saturation state events on the California continental shelf
Posted on EPOCA: 09 Jun 2013 — Hauri C., Gruber N., McDonnell A. M. P. & Vogt M., in press. Geophysical Research Letters. Ocean acidification will progress in an episodic manner, yet this has rarely been considered. Here, we investigate how the intensity, duration, and severity of episodic low aragonite

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology The increase in atmospheric CO2 due to anthropogenic activity results in an acidification of the surface waters of
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
