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...

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...

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...

Coral calcification from skeletal records revisited
International Atomic Energy Agency (IAEA) Publications
Skeletal growth records in annually banded massive coral skeletons are an under-exploited archive of coral responses to environmental changes. Average linear extension and calcification...

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...

Habitat compression and expansion of sea urchins in response to changing climate conditions on the California continental shelf and slope (1994–2013)
International Atomic Energy Agency (IAEA) Publications
Echinoid sea urchins with distributions along the continental shelf and slope of the eastern Pacific often dominate the megafauna community. This occurs despite their exposure to...

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...

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...

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...

Spatial patterns of Anchoveta (Engraulis ringens) eggs and larvae in relation to pCO2 in the Peruvian upwelling system
International Atomic Energy Agency (IAEA) Publications
Large and productive fisheries occur in regions experiencing or projected to experience ocean acidification. Anchoveta (Engraulis ringens) constitute the world's largest single-species...

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...

Growing up in the temperate zone: age, growth, calcification and carbonate mineralogy of Melicerita chathamensis (Bryozoa) in southern New Zealand
International Atomic Energy Agency (IAEA) Publications
The cheilostome bryozoan Melicerita chathamensis from the continental shelf around southern New Zealand is unusual in having macroscopic annual growth checks. It thus presents an...

Behavior of brooded coral larvae in response to elevated pCO2
International Atomic Energy Agency (IAEA) Publications
Elevated pCO2 threatens coral reefs through impaired calcification. However, the extent to which elevated pCO2 affects the distribution of the pelagic larvae of scleractinian corals, and...

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...
