Calcium carbonate (CaCO3) sediment dissolution under elevated concentrations of carbon dioxide (CO2) and nitrate (NO3−)

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA), attributed to the sequestration of atmospheric carbon dioxide (CO2) into the surface ocean, and coastal eutrophication, attributed in part to land-use change and...

Nutrient pollution disrupts key ecosystem functions on coral reefs

International Atomic Energy Agency (IAEA) Publications

There is a long history of examining the impacts of nutrient pollution and pH on coral reefs. However, little is known about how these two stressors interact and influence coral reef...

Global dissolution effects on planktonic foraminiferal Mg/Ca ratios controlled by the calcite-saturation state of bottom waters

International Atomic Energy Agency (IAEA) Publications

Mg/Ca ratios of planktonic foraminiferal tests are important tools for reconstructing past ocean temperatures at different levels of the upper water column. Yet numerous studies suggest a...

Permeable coral reef sediment dissolution driven by elevated CO2 and porewater advection

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is expected to drive the transition of coral reef ecosystems from net calcium carbonate (CaCO3) precipitating to net dissolving within the next century. Although...

The detrimental effects of CO2-driven chronic acidification on juvenile Pacific abalone (Haliotis discus hannai)

International Atomic Energy Agency (IAEA) Publications

To test the effects of chronic stress caused by CO2-driven decreases in pH (NBS scale) on molluscs, juvenile Pacific abalone (Haliotis discus hannai), an economically important gastropod,...

Effects of ocean acidification and global warming on reef bioerosion—lessons from a clionaid sponge

International Atomic Energy Agency (IAEA) Publications

Coral reefs are under threat, exerted by a number of interacting effects inherent to the present climate change, including ocean acidification and global warming. Bioerosion drives reef...

Publications

Sponge bioerosion on changing reefs: ocean warming poses physiological constraints to the success of a photosymbiotic excavating sponge

International Atomic Energy Agency (IAEA) Publications

Excavating sponges are prominent bioeroders on coral reefs that in comparison to other benthic organisms may suffer less or may even benefit from warmer, more acidic and more eutrophic...

Publications

Bryozoans as southern sentinels of ocean acidification: a major role for a minor phylum

International Atomic Energy Agency (IAEA) Publications

Rapid anthropogenic production of CO2 has driven the carbonate chemistry of the sea, causing lowered pH in surface waters. Increasingly, scientists are called on to study ocean...

Net loss of CaCO3 from a subtropical calcifying community due to seawater acidification: mesocosm-scale experimental evidence

International Atomic Energy Agency (IAEA) Publications

Acidification of seawater owing to oceanic uptake of atmospheric CO2 originating from human activities such as burning of fossil fuels and land-use changes has raised serious concerns...

Changes in pteropod distributions and shell dissolution across a frontal system in the California Current System

International Atomic Energy Agency (IAEA) Publications

We tested the sensitivity of the vertical distributions and shell dissolution patterns of thecosome pteropods to spatial gradients associated with an eddy-associated front in the southern...

Water flow modulates the response of coral reef communities to ocean acidification

International Atomic Energy Agency (IAEA) Publications

By the end of the century coral reefs likely will be affected negatively by ocean acidification (OA), but both the effects of OA on coral communities and the crossed effects of OA with...

Publications

Contrasting effects of ocean acidification on tropical fleshy and calcareous algae

International Atomic Energy Agency (IAEA) Publications

Despite the heightened awareness of ocean acidification (OA) effects on marine organisms, few studies empirically juxtapose biological responses to CO2 manipulations across functionally...

Intraspecific variability in the response of the edible mussel Mytilus chilensis (hupe) to ocean acidification

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) has been shown to affect significantly the net calcification process and growth rate of many marine calcifying organisms. Recent studies have shown that the...

CO32- concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat, Hawaii

International Atomic Energy Agency (IAEA) Publications

The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how seawater pCO2 affects the balance between calcification and dissolution of...
