Development and application of foraminiferal carbonate system proxies to quantify ocean acidification in the California Current

Published 22 February 2017   The oceanic uptake of anthropogenic carbon has mitigated climate change, but has also resulted in a global average 0.1 decline in surface ocean pH over 20th century known as ocean acidification. The parallel reduction in carbonate ion concentration ([CO32-]) and the saturation state of seawater (Ω)

New ocean, new needs: Application of pteropod shell dissolution as a biological indicator for marine resource management

February 3   Pteropods, planktonic marine snails with a cosmopolitan distribution, are highly sensitive to changing ocean chemistry. Graphical abstract shows pteropod responses to be related to aragonite saturation state, with progressing decrease in Ωar causing deteriorating biological conditions. Under high saturation state (Ωar > 1.1; zone 0), pteropods are

Mechanistic understanding of ocean acidification impacts on larval feeding physiology and energy budgets of the mussel Mytilus californianus

24 January 2017   Ocean acidification (OA)—a process describing the ocean’s increase in dissolved carbon dioxide ( pCO2) and a reduction in pH and aragonite saturation state (Ωar) due to higher concentrations of atmospheric CO2—is considered a threat to bivalve mollusks and other marine calcifiers. While many studies have focused
