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...

Publications
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...

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....

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...

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...

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...

Uranium in larval shells as a barometer of molluscan ocean acidification exposure
International Atomic Energy Agency (IAEA) Publications
As the ocean undergoes acidification, marine organisms will become increasingly exposed to reduced pH, yet variability in many coastal settings complicates our ability to accurately...

Changes in water quality following opening and closure of a bar-built estuary (Pescadero, California)
International Atomic Energy Agency (IAEA) Publications
Bar-built estuaries are coastal environments characterized by the partial closure of the estuary's mouth with a sandbar barrier for extended periods (closed state). Through natural events...

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...

Deducing acidification rates based on short-term time series
International Atomic Energy Agency (IAEA) Publications
We show that, statistically, the simple linear regression (SLR)-determined rate of temporal change in seawater pH ($β$pH), the so-called acidification rate, can be expressed as a linear...
