The influence of abrupt increases in seawater pCO2 on plankton productivity in the subtropical North Pacific Ocean
International Atomic Energy Agency (IAEA) Publications
We conducted a series of experiments to examine short-term (2-5 days) effects of abrupt increases in the partial pressure of carbon dioxide (pCO2) in seawater on rates of primary and...

Projected changes to growth and mortality of Hawaiian corals over the next 100 years
International Atomic Energy Agency (IAEA) Publications
Background Recent reviews suggest that the warming and acidification of ocean surface waters predicated by most accepted climate projections will lead to mass mortality and declining...

Seawater acidification induced immune function changes of haemocytes in Mytilus edulis: a comparative study of CO2 and HCl enrichment
International Atomic Energy Agency (IAEA) Publications
The present study was performed to evaluate the effects of CO2- or HCl-induced seawater acidification (pH 7.7 or 7.1; control: pH 8.1) on haemocytes of Mytilus edulis, and the changes in...

Synergistic effects of elevated carbon dioxide and sodium hypochlorite on survival and impairment of three phytoplankton species
International Atomic Energy Agency (IAEA) Publications
Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent transport...

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)...

Ocean acidification stress index for shellfish (OASIS): Linking Pacific oyster larval survival and exposure to variable carbonate chemistry regimes
International Atomic Energy Agency (IAEA) Publications
Understanding larval bivalve responses to variable regimes of seawater carbonate chemistry requires realistic quantification of physiological stress. Based on a degree-day modeling...

Exposure history determines pteropod vulnerability to ocean acidification along the US West Coast
International Atomic Energy Agency (IAEA) Publications
The pteropod Limacina helicina frequently experiences seasonal exposure to corrosive conditions ($Ømega$ar \textless 1) along the US West Coast and is recognized as one of the species...

Phytoplankton do not produce carbon-rich organic matter in high CO2 oceans
International Atomic Energy Agency (IAEA) Publications
The ocean is a substantial sink for atmospheric carbon dioxide (CO2) released as a result of human activities. Over the coming decades the dissolved inorganic C concentration in the...

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...

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...
