Variations in coral reef net community calcification and aragonite saturation state on local and global scales
… (NCC) to ocean acidification (OA) and declining aragonite saturation state (Ωa) requires a thorough understanding of controls on NCC. The diurnal control of light and net community production (NCP) on NCC confounds the underlying control of Ωa on NCC and must be averaged out in order to predict …

The Combined Effect of Ocean Acidification and Euthrophication on water pH and Aragonite Saturation State in the Northern Gulf of Mexico
… 2011 Mississippi River flood on coastal pH and aragonite saturation states. Data from a model simulation using data collected from the northern Gulf of Mexico indicates that eutrophication is contributing to acidification of subsurface waters and plays a larger role than acidification from …

Seasonal and interannual variability of the marine carbonate system at the ice shelf in the eastern Weddell Gyre and its sensitivity to future ocean acidification
… resulting in possible surface water wintertime aragonite (the more soluble form of calcium carbonate) undersaturation (Ωarag< 1) south of the Antarctic Polar Front by the year 2030 (McNeil and Matear, 2008). An Ocean Acidification study was conducted to determine the seasonal and interannual …

Modeling Departures From Abiotic Expectations During the Calcium Carbonate Precipitation Process
… the carbon and oxygen isotopic composition of aragonite and coexisting spring water; and modeling these experimental results to establish whether precipitation and isotopic fractionation are consistent with abiotic CaCO3 mineralization or better explained via alternative processes. At an …

Pteropod shell condition, locomotion, and long-term population trends in the context of ocean acidification and environmental change
… pteropods are planktonic mollusks that form aragonite shells and that may experience increased dissolution and other adverse effects due to ocean acidification. This thesis focuses on assessing the possible biological effects of ocean acidification on the shells and locomotion of pteropods …

Investigating a mitigation strategy for acidic sediment conditions in support of First Nation Bivalve restoration initiatives : the effect of shell hash on porewater pH and carbonate saturation states in Burrard Inlet, British Columbia, Canada
… in Burrard Inlet, Canada. Porewater pH and aragonite saturation states (Ωarg) were evaluated under different tidal conditions and pH treatments. Significant differences were found in porewater acidity and Ωarg between sites, tidal conditions, and pH treatments. There was no consistent shell …
