The absorption of atmospheric carbon dioxide (CO2) into the ocean lowers the pH of the waters. This so-called ocean acidification could have important consequences for marine ecosystems. To better understand the extent of this ocean acidification in coastal waters, we conducted hydrographic surveys along the continental shelf of western North America from central Canada to northern Mexico. We observed seawater that is undersaturated with respect to aragonite upwelling onto large portions of the…

Inorganic carbon dynamics during northern California coastal upwelling
Microbial biogeochemistry of coastal upwelling regimes in a changing ocean
The coastal upwelling regimes located along the eastern boundaries of the Pacific and Atlantic Ocean basins are small in size, but make a disproportionate contribution to the productivity and…
Ocean acidification in the three oceans surrounding northern North America
[1] The uptake of anthropogenic CO2 drives ocean acidification, with attendant effects on the saturation state of calcium carbonate (Ω) and marine ecosystems. Here, we examine ocean acidification…
Acidification of subsurface coastal waters enhanced by eutrophication
Human inputs of nutrients to coastal waters can lead to the excessive production of algae, a process known as eutrophication. Microbial consumption of this organic matter lowers oxygen levels in the…
Vulnerability of a semienclosed estuarine sea to ocean acidification in contrast with hypoxia
The Strait of Georgia (SoG) is a large semienclosed estuary that spatially dominates the Salish Sea on the North American Pacific coast. The region is well populated, harbors significant aquaculture,…
Ocean acidification in the California Current System
. Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with regard to the…
Calcium carbonate corrosivity in an Alaskan inland sea
Ocean acidification is the hydrogen ion increase caused by the oceanic uptake of anthropogenic CO2, and is a focal point in marine biogeochemistry, in part, because this chemical reaction reduces…
Features of coastal upwelling regions that determine net air-sea CO2 flux
The influence of the coastal ocean on global net annual air-sea CO2 fluxes remains uncertain. However, it is well known that air-sea pCO2 disequilibria can be large (ocean pCO2 ranging from ∼400 µatm…

Ocean acidification in the subtropical North Pacific estimated from accumulated carbonate data
The recent uptake of anthropogenic carbon by the ocean brings about changes in the surface-ocean carbon cycle that could result in ocean acidification with subsequent serious effects on marine…

Impact of Anthropogenic CO2 on the CaCO3 System in the Oceans
TLDR
The in situ CaCO3 dissolution rates for the global oceans from total alkalinity and chlorofluorocarbon data are estimated, and the future impacts of anthropogenic CO2 on Ca CO3 shell–forming species are discussed.
Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
TLDR
13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.
