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 “core-top” screen for trace element proxies of environmental conditions and growth rates in the calcite skeletons of bamboo corals (Isididae)
International Atomic Energy Agency (IAEA) Publications
We test for trace element proxies in the high-magnesium calcite fraction of bamboo coral internodes by comparing environmental conditions and growth rates to the specimen-mean...

Early development of undulated surf clam, Paphia undulate under elevated pCO2
International Atomic Energy Agency (IAEA) Publications
Increasing atmospheric CO2 can decrease the seawater pH and carbonate ions, which may adversely affect the larval survival of calcareous animals. In this study, we simulated future...

Potential future coral habitats around Japan depend strongly on anthropogenic CO2 emissions
International Atomic Energy Agency (IAEA) Publications
Using the results from the NCAR CSM1.4-coupled global carbon cycle–climate model under the Intergovernmental Panel on Climate Change (IPCC) emission scenarios SRES A2 and B1, we estimated...

Dissolution: the Achilles' heel of the triton shell in an acidifying ocean
International Atomic Energy Agency (IAEA) Publications
Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution...

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...

Emiliania huxleyi shows identical responses to elevated pCO2 in TA and DIC manipulations
International Atomic Energy Agency (IAEA) Publications
With respect to their sensitivity to ocean acidification, calcifiers such as the coccolithophore Emiliania huxleyi have received special attention, as the process of calcification seems...

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...

Early benthic juvenile Parvulastra exigua (Asteroidea) are tolerant to extreme acidification and warming in its intertidal habitat
International Atomic Energy Agency (IAEA) Publications
Habitat warming and acidification experienced by intertidal invertebrates are potentially detrimental to sensitive early post-larvae of benthic marine invertebrates. To determine the...

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...

Respiratory response of the intertidal seastar Parvulastra exigua to contemporary and near-future pulses of warming and hypercapnia
International Atomic Energy Agency (IAEA) Publications
As typical of intertidal invertebrates the asterinid seastar Parvulastra exigua experiences marked variation in environmental temperature and pH/pCO2 due to tidal exchange and diurnal...

Exploring the “Sharkcano”: biogeochemical observations of the Kavachi submarine volcano (Solomon Islands)
International Atomic Energy Agency (IAEA) Publications
An expedition to the Kavachi submarine volcano (Solomon Islands) in January 2015 was serendipitously timed with a rare lull in volcanic activity that permitted access to the inside of...

Impact of ocean acidification on phytoplankton assemblage, growth, and DMS production following Fe-dust additions in the NE Pacific high-nutrient, low-chlorophyll waters
International Atomic Energy Agency (IAEA) Publications
Ocean acidification (OA) is likely to have an effect on the fertilizing potential of desert dust in high-nutrient, low-chlorophyll oceanic regions, either by modifying iron (Fe)...

Interactive network configuration maintains bacterioplankton community structure under elevated CO2 in a eutrophic coastal mesocosm experiment
International Atomic Energy Agency (IAEA) Publications
There is increasing concern about the effects of ocean acidification on marine biogeochemical and ecological processes and the organisms that drive them, including marine bacteria. Here,...

Shift from coral to macroalgae dominance on a volcanically acidified reef
International Atomic Energy Agency (IAEA) Publications
Rising anthropogenic CO2 in the atmosphere is accompanied by an increase in oceanic CO2 and a concomitant decline in seawater pH (ref. 1). This phenomenon, known as ocean acidification...

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...
