P pH variability was particularly pronounced in coastal ecosystems with strong decoupling of production and respiration processes, seasonally or through stratification, demonstrating that coastal pH can be managed by controlling inputs of nutrients, organic matter, and alkalinity.

Biological and Physical Controls on Multidecadal Acidification in a Eutrophic Estuary

This work investigated eutrophication impacts on acidification in a central California estuary, Elkhorn Slough, which receives high nutrient loads from intensive surrounding agriculture and upwelling of the California Current System and revealed acidification trends over two decades were more pronounced near the marine inlet.

Bi-decadal variability in physico-biogeochemical characteristics of temperate coastal ecosystems: from large-scale to local drivers

Coastal marine ecosystems, which play a crucial role in the biogeochemical and ecological functioning of the Earth, are highly sensitive to the combined effects of climate and human activities.

Seasonal variability of coastal pH and CO2 using an oceanographic buoy in the Canary Islands

Ocean acidification, caused by the absorption of carbon dioxide (CO2) from the atmosphere into the ocean, ranks among the most critical consequences of climate change for marine ecosystems. Most

A baseline assessment of coastal pH variability in a temperate South African embayment: implications for biological ocean acidification research

This is the first comprehensive pH-monitoring study to be implemented in a nearshore coastal area in Africa and provides recommendations for monitoring in other understudied regions.

Disentangling the Effects of Global and Regional Drivers on Diverse Long‐Term pH Trends in Coastal Waters

Unlike declines of pH in the open ocean on the total scale (pHT), coastal systems have shown complex long‐term trends in pHT due to a multitude of global and regional drivers. These drivers include

Decoupling of Estuarine Hypoxia and Acidification as Revealed by Historical Water Quality Data.

Hypoxia and acidification are commonly coupled in eutrophic aquatic environments because aerobic respiration is usually dominant in bottom waters and can lower dissolved oxygen (DO) and pH

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

Eutrophication induced CO₂-acidification of subsurface coastal waters: interactive effects of temperature, salinity, and atmospheric PCO₂.

Model calculations show that the acidification from respiratory CO(2) inputs interacts in a complex fashion with that from increasing atmospheric CO( 2) and that these pH effects can be more than additive in seawater at intermediate to higher temperatures.

It is suggested that physical and biogeochemical processes alter the acidification rate with depth and time and must therefore be given due consideration when designing and interpreting ocean pH monitoring efforts and predictive models.

Estuarine acidification dynamics based on oxygen, hydrogen sulfide, pH, dissolved inorganic carbon and total alkalinity data from the Chesapeake Bay are reported, showing that a pH minimum occurs in mid-depths where acids are generated as a result of H2S oxidation in waters mixed upward from the anoxic depths.
