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...

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...

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...

Publications
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...

Coral records of reef-water pH across the central Great Barrier Reef, Australia: assessing the influence of river runoff on inshore reefs
International Atomic Energy Agency (IAEA) Publications
The boron isotopic ($δ$11Bcarb) compositions of long-lived Porites coral are used to reconstruct reef-water pH across the central Great Barrier Reef (GBR) and assess the impact of river...

Influence of glacier melting and river discharges on the nutrient distribution and DIC recycling in the Southern Chilean Patagonia
International Atomic Energy Agency (IAEA) Publications
The Chilean Patagonia constitutes one of the most important and extensive fjord systems worldwide, therefore can be used as a natural laboratory to elucidate the pathway of both organic...

Ecological effects of ocean acidification and habitat complexity on reef-associated macroinvertebrate communities
International Atomic Energy Agency (IAEA) Publications
The ecological effects of ocean acidification (OA) from rising atmospheric carbon dioxide (CO2) on benthic marine communities are largely unknown. We investigated in situ the consequences...

Publications
Internal pH regulation facilitates in situ long-term acclimation of massive corals to end-of-century carbon dioxide conditions.
International Atomic Energy Agency (IAEA) Publications
The resilience of tropical corals to ocean acidification depends on their ability to regulate the pH within their calcifying fluid (pHcf). Recent work suggests pHcf homeostasis under...
