Sponge bioerosion on changing reefs: ocean warming poses physiological constraints to the success of a photosymbiotic excavating sponge
International Atomic Energy Agency (IAEA) Publications
Excavating sponges are prominent bioeroders on coral reefs that in comparison to other benthic organisms may suffer less or may even benefit from warmer, more acidic and more eutrophic...

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...

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...

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...

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...

Elevated pCO2 alters marine heterotrophic bacterial community composition and metabolic potential in response to a pulse of phytoplankton organic matter
International Atomic Energy Agency (IAEA) Publications
Factors that affect the respiration of organic carbon by marine bacteria can alter the extent to which the oceans act as a sink of atmospheric carbon dioxide. We designed seawater...

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...

Long-term exposure to elevated carbon dioxide does not alter activity levels of a coral reef fish in response to predator chemical cues
International Atomic Energy Agency (IAEA) Publications
ABSTRACT: Levels of dissolved carbon dioxide (CO2) projected to occur in the world's oceans in the near future have been reported to increase swimming activity and impair predator...

Effects of fishing and acidification-related benthic mortality on the southeast Australian marine ecosystem
International Atomic Energy Agency (IAEA) Publications
Oceanic uptake of anthropogenic carbon dioxide (CO2) is altering the carbonate chemistry of seawater, with potentially negative consequences for many calcifying marine organisms. At the...

Size-dependent physiological responses of the branching coral Pocillopora verrucosa to elevated temperature and pCO2
International Atomic Energy Agency (IAEA) Publications
Body size has large effects on organism physiology, but these effects remain poorly understood in modular animals with complex morphologies. Using two trials of a ∼24 day experiment...

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...

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...

Anthropogenic carbon distribution in the eastern South Pacific Ocean
International Atomic Energy Agency (IAEA) Publications
We present results of the CO2/carbonate system from the BIOSOPE cruise in the Eastern South Pacific Ocean, in an area not sampled previously. In particular, we present estimates of the...

Marine projections of warming and ocean acidification in the Australasian region
International Atomic Energy Agency (IAEA) Publications
In response to increasing carbon dioxide emissions the oceans have become warmer and more acidic. In this paper, the ability of Earth System Models to simulate observed temperature 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...

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...

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...

Impacts of near future sea surface pH and temperature conditions on fertilisation and embryonic development in Centrostephanus rodgersii from northern New Zealand and northern New South Wales, Australia
International Atomic Energy Agency (IAEA) Publications
Oceans are warming and becoming more acidic. While higher temperature and lower pH can have negative effects on fertilisation and development of marine invertebrates, warming may...
