Metabolically-induced pH fluctuations by some coastal calcifiers exceed projected 22nd century ocean acidification: a mechanism for differential susceptibility?
International Atomic Energy Agency (IAEA) Publications
Anthropogenically-mediated decreases in pH, termed ocean acidification (OA), may be a major threat to marine organisms and communities. Research has focussed mainly on tropical coral...

A year in the life of a central California kelp forest: physical and biological insights into biogeochemical variability
International Atomic Energy Agency (IAEA) Publications
Kelp forests are among the world's most productive marine ecosystems, yet little is known about their biogeochemistry. This study presents a 14-month time series (July 2013–August 2014)...

Greenhouse conditions induce mineralogical changes and dolomite accumulation in coralline algae on tropical reefs
International Atomic Energy Agency (IAEA) Publications
Human-induced ocean acidification and warming alter seawater carbonate chemistry reducing the calcification of reef-building crustose coralline algae (CCA), which has implications for...

CO2-driven seawater acidification increases photochemical stress in a green alga
International Atomic Energy Agency (IAEA) Publications
Increased CO2 and associated acidification in seawater, known as ocean acidification, decreases calcification of most marine calcifying organisms. However, there is little information...

An ocean acidification acclimatised green tide alga is robust to changes of seawater carbon chemistry but vulnerable to light stress
International Atomic Energy Agency (IAEA) Publications
Ulva is the dominant genus in the green tide events and is considered to have efficient CO2 concentrating mechanisms (CCMs). However, little is understood regarding the impacts of ocean...

Disrupting the effects of synergies between stressors: improved water quality dampens the effects of future CO2 on a marine habitat
International Atomic Energy Agency (IAEA) Publications
Summary Synergies among stressors drive unanticipated changes to alternative states, yet little has been done to assess whether alleviating one or more contributing stressors may disrupt...

Abiotic and biotic interactions in the diffusive boundary layer of kelp blades create a potential refuge from ocean acidification
International Atomic Energy Agency (IAEA) Publications
1.Seaweeds are able to modify the chemical environment at their surface, in a micro‐zone called the diffusive boundary layer (DBL), via their metabolic processes controlled by light...

Will coral islands maintain their growth over the next century? A deterministic model of sediment availability at Lady Elliot Island, Great Barrier Reef
International Atomic Energy Agency (IAEA) Publications
A geomorphic assessment of reef system calcification is conducted for past (3200 Ka to present), present and future (2010-2100) time periods. Reef platform sediment production is...

Saturating light and not increased carbon dioxide under ocean acidification drives photosynthesis and growth in (Chlorophyta)
International Atomic Energy Agency (IAEA) Publications
Carbon physiology of a genetically identified Ulva rigida was investigated under different CO2(aq) and light levels. The study was designed to answer whether (1) light or exogenous...

Carbon and nitrogen accumulation in the economic seaweed Gracilaria lemaneiformis affected by ocean acidification and increasing temperature
International Atomic Energy Agency (IAEA) Publications
During mariculture period, maricultured macroalga Gracilaria lemaneiformis experienced seasonal temperature changes. In this study, we examine the effects of predicted ocean acidification...

Future herbivory: the indirect effects of enriched CO2 may rival its direct effects
International Atomic Energy Agency (IAEA) Publications
Variation in rates of herbivory may be driven by direct effects of the abiotic environment on grazers, as well as indirect effects mediated by their food. Disentangling these direct and...

Benthic buffers and boosters of ocean acidification on coral reefs
International Atomic Energy Agency (IAEA) Publications
Ocean acidification is a threat to marine ecosystems globally. In shallow-water systems, however, ocean acidification can be masked by benthic carbon fluxes, depending on community...

Boosted nutritional quality of food by CO2 enrichment fails to offset energy demand of herbivores under ocean warming, causing energy depletion and mortality
International Atomic Energy Agency (IAEA) Publications
The CO2-boosted trophic transfer from primary producers to herbivores has been increasingly discovered at natural CO2 vents and in laboratory experiments. Despite the emerging knowledge...
