Since the Industrial Revolution, the North Atlantic Ocean has been accumulating anthropogenic carbon dioxide (CO2) and experiencing ocean acidification, that is, an increase in the concentration of hydrogen ions (a reduction in pH) and a reduction in the concentration of carbonate ions. The latter causes the ‘aragonite saturation horizon’—below which waters are undersaturated with respect to a particular calcium carbonate, aragonite—to move to shallower depths (to shoal), exposing corals to… 
Acidification of the Nordic Seas
Abstract. Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean
The Northeast Atlantic is running out of excess carbonate in the horizon of cold-water corals communities
TLDR
A progression to undersaturation with respect to aragonite is shown that could compromise the conservation of the habitats and ecosystem services developed by benthic marine calcifiers inhabiting that depth-range, such as the cold-water corals (CWC) communities.
Contrasting drivers and trends of ocean acidification in the subarctic Atlantic
TLDR
The driver analysis detects that warming contributes up to 50% to the increase in [H+]T at the IRM-TS but has a small positive effect on calcium carbonate saturation, which is partially dampened by the northward advection of water with a relatively low natural CO2 content.
Nordic Seas Acidification
Abstract. Being windows to the deep ocean, the Nordic Seas play an important role in transferring anthropogenic carbon, and thus ocean acidification, to the abyss. Due to its location in high
Current CaCO3 dissolution at the seafloor caused by anthropogenic CO2
TLDR
It is determined that significant anthropogenic dissolution now occurs in the western North Atlantic, amounting to 40–100% of the total seafloor dissolution at its most intense locations, and indicates that a by-product of human activities is currently altering the geological record of the deep sea.
Controls on surface water carbonate chemistry along North American ocean margins
TLDR
It is shown that along the North American Atlantic and Gulf coasts the meridional distributions of dissolved inorganic carbon and carbonate mineral saturation state are controlled by partial equilibrium with the atmosphere resulting in relatively low DIC and high Ω in warm southern waters and the opposite in cold northern waters.
Reduced CaCO3 Flux to the Seafloor and Weaker Bottom Current Speeds Curtail Benthic CaCO3 Dissolution Over the 21st Century
Results from a range of Earth System and climate models of various resolution run under high‐CO2 emission scenarios challenge the paradigm that seafloor CaCO3 dissolution will grow in extent and
Acceleration of Ocean Acidification in the Western North Pacific
Because annual anthropogenic CO2 emissions have grown rapidly over the past decades, there is a concern that anthropogenic CO2 invasion into the ocean may also have caused the rate of ocean
