Rising atmospheric carbon dioxide (CO2), primarily from human fossil fuel combustion, reduces ocean pH and causes wholesale shifts in seawater carbonate chemistry. The process of ocean acidification is well documented in field data, and the rate will accelerate over this century unless future CO2 emissions are curbed dramatically. Acidification alters seawater chemical speciation and biogeochemical cycles of many elements and compounds. One well-known effect is the lowering of calcium carbonate… 
Trends and drivers of sea surface fCO2 and pH changes observed in the Southern Indian Ocean over the last two decades (1998–2019)
Abstract. The decadal changes of the fugacity of CO2 (fCO2) and pH in surface waters are investigated in the Southern Indian Ocean (45° S–57° S) using repeated summer observations, including
Ocean Acidification Mitigates the Negative Effects of Increased Sea Temperatures on the Biomineralization and Crystalline Ultrastructure of Mytilus
Negative impacts of global climate change are predicted for a range of taxa. Projections predict marked increases in sea surface temperatures and ocean acidification (OA), arguably placing calcifying
Sperm Motility Impairment in Free Spawning Invertebrates Under Near-Future Level of Ocean Acidification: Uncovering the Mechanism
The results of this study suggest that the lowering of seawater pH as predicted to occur for 2100, through the inhibition of pHi increase, prevent sperm motility activation, which would result in a corresponding drop in fertilization success.

Relationship between shell integrity of pelagic gastropods and carbonate chemistry parameters at a Scottish Coastal Observatory monitoring site
This data indicates that the presence of carboniferous strata in the North Sea contributes to the vulnerability of these habitats to pollution and the need to protect them from these threats.
Implementation of novel sensors on underwater gliders
Around a quarter of global anthropogenic carbon emissions have been absorbed by the ocean. Underwater gliders have been identified as important tools for gathering information related to climate

Ocean climate impacts on the primary and secondary metabolites of a muricid mollusc
Ocean warming and acidification are current global environmental challenges impacting aquatic organisms. A shift in conditions outside the optimal environmental range for marine species is likely to
Ecosystem‐based management of coral reefs under climate change
It is concluded that designation of climate change‐ready MPAs, integrated with other management strategies involving stakeholders and participation at multiple scales such as marine spatial planning, will be required to maximise coral reef resilience under climate change.
Art and Science: A Case Study of their Interconnectedness in the Marine Natural Sciences
Science and art are interrelated in the form of scientific illustration: the act of observing a subject and translating the gained knowledge into a visual form. Humans have found inspiration from the


Impact of anthropogenic atmospheric nitrogen and sulfur deposition on ocean acidification and the inorganic carbon system
The alterations in surface water chemistry from anthropogenic nitrogen and sulfur deposition are a few percent of the acidification and DIC increases due to the oceanic uptake of anthropogenic CO2, however, the impacts are more substantial in coastal waters, where the ecosystem responses to ocean acidification could have the most severe implications for mankind.

Postindustrial enhancement of aragonite undersaturation in the upper tropical and subtropical Atlantic Ocean: The role of fossil fuel CO2
The dissolution of aragonite particles in the ocean primarily depends on the degree of undersaturation of seawater with respect to that mineral. Most of the upper Atlantic Ocean, particularly north
Calcium carbonate budget in the Atlantic Ocean based on water column inorganic carbon chemistry
Recent independent lines of evidence suggest that the dissolution of calcium carbonate (CaCO3) particles is substantial in the upper ocean above the calcite 100% saturation horizon. This
Impact of Anthropogenic CO2 on the CaCO3 System in the Oceans
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.
Production and accumulation of calcium carbonate in the ocean: Budget of a nonsteady state
Present-day production of CaCO3 in tne world ocean is calculated to be about 5 billion tons (bt) per year, of which about 3 bt accumulate in sediments; the other 40% is dissolved. Nearly half of the
