A synthesis of long-term changes in pH of coastal ecosystems shows that, in contrast to the uniform trends of open-ocean acidification (-0.0004 to -0.0026 pH units yr-1) driven by increased atmospheric CO2, coastal ecosystems display a much broader range of trends (-0.023 to 0.023 pH units yr-1) and are as likely to show long-term increase as decline in pH. The majority of the 83 investigated coastal ecosystems displayed nonlinear trends, with seasonal and interannual variations exceeding 1 pH… 
Mechanisms Driving Decadal Changes in the Carbonate System of a Coastal Plain Estuary
Understanding decadal changes in the coastal carbonate system is essential for predicting how the health of these waters responds to anthropogenic drivers, such as changing atmospheric conditions and
High‐frequency pH time series reveals pronounced seasonality in Arctic coastal waters
The accelerated rate of climate change in the Arctic Ocean occurs in conjunction with a system known for its extreme seasonal variability. Here, we present 2 years of continuous pH, salinity, and
Attributing Controlling Factors of Acidification and Hypoxia in a Deep, Nutrient-Enriched Estuarine Embayment
Measuring and attributing controlling factors of acidification and hypoxia are essential for management of coastal ecosystems affected by those stressors. We address this using surveys in the Firth
Temporal and Spatial Variability of the CO2 System in a Riverine Influenced Area of the Mediterranean Sea, the Northern Adriatic
Coastal ecosystems are subject to multiple processes that drive pH change over time. Therefore, efforts to understand the variability in the coastal carbonate system are crucial to assess the marine
Decadal Dynamics of the CO2 System and Associated Ocean Acidification in Coastal Ecosystems of the North East Atlantic Ocean
Weekly and bi-monthly carbonate system parameters and ancillary data were collected from 2008 to 2020 in three coastal ecosystems of the southern Western English Channel (sWEC) (SOMLIT-pier and
The Seasonal Phases of an Arctic Lagoon Reveal Non-linear pH Extremes
Abstract. The western Arctic Ocean, including its shelves and coastal habitats, has become a focus in ocean acidification research over the past decade as the colder waters of the region and the
Characterizing biogeochemical fluctuations in a world of extremes: A synthesis for temperate intertidal habitats in the face of global change
Characterisation of biogeochemical fluctuations in a world of extremes demonstrates the variable conditions that intertidal biota routinely experience and highlights potential microhabitat-specific vulnerabilities and climate change refugia.
Calcium carbonate alters the functional response of coastal sediments to eutrophication-induced acidification
By identifying the links between eutrophication, sediment biogeochemistry and benthic ecosystem structure and function in situ, this study represents a crucial step forward in understanding the ecological effects of coastal acidification and the role of biogenic CaCO3 in moderating responses.
Biogeochemical functioning of the Baltic Sea
Abstract. Location, specific topography, and hydrographic setting together with climate change and strong anthropogenic pressure are the main factors shaping the biogeochemical functioning and thus


Dramatic Variability of the Carbonate System at a Temperate Coastal Ocean Site (Beaufort, North Carolina, USA) Is Regulated by Physical and Biogeochemical Processes on Multiple Timescales
P pH and dissolved inorganic carbon (DIC) is presented at time intervals spanning 1 hour to >1 year from a dynamic, coastal, temperate marine system to characterize the carbonate system at multiple time scales.
Attributing seasonal pH variability in surface ocean waters to governing factors
On‐going ocean acidification and increasing availability of high‐frequency pH data have stimulated interest to understand seasonal pH dynamics in surface waters. Here we show that it is possible to
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
Physical and biogeochemical modulation of ocean acidification in the central North Pacific
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.
Photosynthetic activity buffers ocean acidification in seagrass meadows
Macrophytes growing in shallow coastal zones characterised by intense metabolic activity have the capacity to modify pH within their canopy and beyond. We observed diel pH changes in shallow (5–12 m)
Redox reactions and weak buffering capacity lead to acidification in the Chesapeake Bay
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.
Seasonal and long-term changes in pH in the Dutch coastal zone
Abstract. Recent observations and modelling studies suggest that biogeochemical changes can mask atmospheric CO2-induced pH decreases. Data collected by the Dutch monitoring authorities in different

Increased freshwater discharge shifts the trophic balance in the coastal zone of the northern Baltic Sea
Increased precipitation is one projected outcome of climate change that may enhance the discharge of freshwater to the coastal zone. The resulting lower salinity, and associated discharge of both
Carbonate chemistry in the coastal zone responds more strongly to eutrophication than ocean acidification.
The accumulation of anthropogenic CO2 in the ocean has altered carbonate chemistry in surface waters since preindustrial times and is expected to continue to do so in the coming centuries. Changes in
