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

Two Decades of Pacific Anthropogenic Carbon Storage and Ocean Acidification Along GO-SHIP Sections P16 and P02
21 January 2017 Abstract A modified version of the extended multiple linear regression (eMLR) method is used to estimate anthropogenic carbon concentration (Canth) changes along the Pacific P02 and P16 hydrographic sections over the past two decades. P02 is a zonal section crossing the North Pacific at 30°N and P16
Risks of ocean acidification in the California Current food web and fisheries: ecosystem model projections
Published 13 January 2017 The benefits and ecosystem services that humans derive from the oceans are threatened by numerous global change stressors, one of which is ocean acidification. Here, we describe the effects of ocean acidification on an upwelling system that already experiences inherently low pH conditions, the California Current.
Ocean acidification to hit West Coast Dungeness crab fishery, new assessment shows
The acidification of the ocean expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast’s marine food web, but not necessarily in the ways you might expect, new research shows. Dungeness crabs, for example, will likely suffer as their food sources decline.
Measurements of pCO2 and pH from an autonomous surface vehicle in a coastal upwelling system
Published 10 January 2017 Anthropogenic input of carbon dioxide (CO2) into the atmosphere and its uptake by the ocean with associated changes in ocean chemistry have created an urgent need to expand coverage of sea surface and atmospheric carbon dioxide observations. Conventional sampling platforms (e.g. ships and moorings) do not
