Ocean acidification causes bleaching and productivity loss in coral reef builders

International Atomic Energy Agency (IAEA) Publications

Ocean acidification represents a key threat to coral reefs by reducing the calcification rate of the major reef framework builders. In addition, acidification is likely to affect the...

Publications

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...

Publications

Effect of seawater temperature, pH, and nutrients on the distribution and character of low abundance shallow water benthic foraminifera in the Galápagos

International Atomic Energy Agency (IAEA) Publications

In order to help predict the effects of anthropogenic stressors on shallow water carbonate environments, it is important to focus research on regions containing natural oceanographic...

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

Warmer more acidic conditions cause decreased productivity and calcification in subtropical coral reef sediment-dwelling calcifiers

International Atomic Energy Agency (IAEA) Publications

The effects of elevated CO2 and temperature on photosynthesis and calcification in the calcifying algae Halimeda macroloba and Halimeda cylindracea and the symbiont-bearing benthic...

Publications

Symbiodinium mitigate the combined effects of hypoxia and acidification on a non-calcifying cnidarian

International Atomic Energy Agency (IAEA) Publications

Anthropogenic nutrient inputs enhance microbial respiration within many coastal ecosystems, driving concurrent hypoxia and acidification. During photosynthesis, Symbiodinium spp., the...

Publications

Relationships between temperature, pH, and crusting on Mg/Ca ratios in laboratory-grown Neogloboquadrina foraminifera

International Atomic Energy Agency (IAEA) Publications

Mg/Ca ratio paleothermometry in foraminifera is an important tool for the reconstruction and interpretation of past environments. However, existing Mg/Ca:temperature relationships for...

Publications

Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes

International Atomic Energy Agency (IAEA) Publications

Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms,...

Publications

Tropical CO2 seeps reveal the impact of ocean acidification on coral reef invertebrate recruitment

International Atomic Energy Agency (IAEA) Publications

Rising atmospheric CO2 concentrations are causing ocean acidification by reducing seawater pH and carbonate saturation levels. Laboratory studies have demonstrated that many larval and...

Publications

Host and symbionts in Pocillopora damicornis larvae display different transcriptomic responses to ocean acidification and warming

International Atomic Energy Agency (IAEA) Publications

As global ocean change progresses, reef-building corals and their early life history stages will rely on physiological plasticity to tolerate new environmental conditions. Larvae from...

Physiological response to elevated temperature and pCO2 varies across four Pacific coral species: Understanding the unique host+symbiont response

International Atomic Energy Agency (IAEA) Publications

The physiological response to individual and combined stressors of elevated temperature and pCO2 were measured over a 24-day period in four Pacific corals and their respective symbionts...
