Climatic modulation of recent trends in ocean acidification in the California Current System
International Atomic Energy Agency (IAEA) Publications
We reconstruct the evolution of ocean acidification in the California Current System (CalCS) from 1979 through 2012 using hindcast simulations with an eddy-resolving ocean biogeochemical...

The role of ocean acidification in systemic carbonate mineral suppression in the Bering Sea
International Atomic Energy Agency (IAEA) Publications
Ocean acidification driven by absorption of anthropogenic carbon dioxide (CO2) from the atmosphere is now recognized as a systemic, global process that could threaten diverse marine...

Conservative and non-conservative variations of total alkalinity on the Southeastern Bering Sea Shelf
International Atomic Energy Agency (IAEA) Publications
Recent observations of calcium carbonate (CaCO3) mineral undersaturations on the Bering Sea Shelf have prompted new interest in the physical and biological factors that control the...

Influence of post-Tehuano oceanographic processes in the dynamics of the CO system in the Gulf of Tehuantepec, Mexico
International Atomic Energy Agency (IAEA) Publications
This investigation reports, for the first time, results of CO2 system variables in the Gulf of Tehuantepec, located in the Mexican tropical Pacific. We quantified the post-Tehuano...

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...

Seasonal patterns in aragonite saturation state on the southern California continental shelf
International Atomic Energy Agency (IAEA) Publications
Shoaling of the saturation horizon for aragonite in the California Current System has been well-documented; however, these reports are based primarily on surveys conducted in waters off...

Reconstructing aragonite saturation state based on an empirical relationship for Northern California
International Atomic Energy Agency (IAEA) Publications
Ocean acidification is a global phenomenon with highly regional spatial and temporal patterns. In order to address the challenges of future ocean acidification at a regional scale, it is...

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...

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...

Using present-day observations to detect when anthropogenic change forces surface ocean carbonate chemistry outside preindustrial bounds
International Atomic Energy Agency (IAEA) Publications
One of the major challenges to assessing the impact of ocean acidification on marine life is detecting and interpreting long-term change in the context of natural variability. This study...

Deep oceans may acidify faster than anticipated due to global warming
International Atomic Energy Agency (IAEA) Publications
Oceans worldwide are undergoing acidification due to the penetration of anthropogenic CO2 from the atmosphere1,2,3,4. The rate of acidification generally diminishes with increasing depth....

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,...

The influence of Pacific Equatorial Water on fish diversity in the southern California Current System
International Atomic Energy Agency (IAEA) Publications
The California Undercurrent transports Pacific Equatorial Water (PEW) into the Southern California Bight from the eastern tropical Pacific Ocean. PEW is characterized by higher...

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...

Risks of hypoxia and acidification in the high energy coastal environment near Victoria, Canada's untreated municipal sewage outfalls
International Atomic Energy Agency (IAEA) Publications
Wastewater disposal often has deleterious impacts on the receiving environment. Low dissolved oxygen levels are particularly concerning. Here, we investigate the impacts on dissolved...

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...
