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...

Net loss of CaCO3 from a subtropical calcifying community due to seawater acidification: mesocosm-scale experimental evidence
International Atomic Energy Agency (IAEA) Publications
Acidification of seawater owing to oceanic uptake of atmospheric CO2 originating from human activities such as burning of fossil fuels and land-use changes has raised serious concerns...

Changes in pteropod distributions and shell dissolution across a frontal system in the California Current System
International Atomic Energy Agency (IAEA) Publications
We tested the sensitivity of the vertical distributions and shell dissolution patterns of thecosome pteropods to spatial gradients associated with an eddy-associated front in the southern...

Habitat compression and expansion of sea urchins in response to changing climate conditions on the California continental shelf and slope (1994–2013)
International Atomic Energy Agency (IAEA) Publications
Echinoid sea urchins with distributions along the continental shelf and slope of the eastern Pacific often dominate the megafauna community. This occurs despite their exposure to...

Ocean warming and acidification have complex interactive effects on the dynamics of a marine fungal disease
International Atomic Energy Agency (IAEA) Publications
Diseases threaten the structure and function of marine ecosystems and are contributing to the global decline of coral reefs. We currently lack an understanding of how climate change...

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...

Mineralogy of deep-sea coral aragonites as a function of aragonite saturation state
International Atomic Energy Agency (IAEA) Publications
In an ocean with rapidly changing chemistry, studies have assessed coral skeletal health under projected ocean acidification (OA) scenarios by characterizing morphological distortions in...

Use of a Free Ocean CO2 Enrichment (FOCE) system to evaluate the effects of ocean acidification on the foraging behavior of a deep-sea urchin
International Atomic Energy Agency (IAEA) Publications
The influence of ocean acidification in deep-sea ecosystems is poorly understood, but is expected to be large owing to the presumed low tolerance of deep-sea taxa to environmental change....

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...

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...

Impaired learning of predators and lower prey survival under elevated CO2: a consequence of neurotransmitter interference
International Atomic Energy Agency (IAEA) Publications
Ocean acidification is one of the most pressing environmental concerns of our time, and not surprisingly, we have seen a recent explosion of research into the physiological impacts and...
