Metabolically-induced pH fluctuations by some coastal calcifiers exceed projected 22nd century ocean acidification: a mechanism for differential susceptibility?
International Atomic Energy Agency (IAEA) Publications
Anthropogenically-mediated decreases in pH, termed ocean acidification (OA), may be a major threat to marine organisms and communities. Research has focussed mainly on tropical coral...

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...

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...

A year in the life of a central California kelp forest: physical and biological insights into biogeochemical variability
International Atomic Energy Agency (IAEA) Publications
Kelp forests are among the world's most productive marine ecosystems, yet little is known about their biogeochemistry. This study presents a 14-month time series (July 2013–August 2014)...

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...

Contrasting impact of future CO2 emission scenarios on the extent of CaCO3 mineral undersaturation in the Humboldt Current System
International Atomic Energy Agency (IAEA) Publications
The eastern boundary upwelling systems are among those regions that are most vulnerable to an ocean acidification‐induced transition toward undersaturated conditions with respect to...

Dynamic patterns and ecological impacts of declining ocean pH in a high-resolution multi-year dataset
International Atomic Energy Agency (IAEA) Publications
Increasing global concentrations of atmospheric CO2 are predicted to decrease ocean pH, with potentially severe impacts on marine food webs, but empirical data documenting ocean pH over...

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,...

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...

Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: implications for ocean acidification
International Atomic Energy Agency (IAEA) Publications
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using...

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...
