Impact of ocean acidification on phytoplankton assemblage, growth, and DMS production following Fe-dust additions in the NE Pacific high-nutrient, low-chlorophyll waters

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is likely to have an effect on the fertilizing potential of desert dust in high-nutrient, low-chlorophyll oceanic regions, either by modifying iron (Fe)...

Technical Note: Maximising accuracy and minimising cost of a potentiometrically regulated ocean acidification simulation system

International Atomic Energy Agency (IAEA) Publications

This article describes a potentiometric ocean acidification simulation system which automatically regulates pH through the injection of 100% CO2 gas into temperature-controlled seawater....

Ocean acidification in the California Current System

International Atomic Energy Agency (IAEA) Publications

Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with...

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,...

Shift from coral to macroalgae dominance on a volcanically acidified reef

International Atomic Energy Agency (IAEA) Publications

Rising anthropogenic CO2 in the atmosphere is accompanied by an increase in oceanic CO2 and a concomitant decline in seawater pH (ref. 1). This phenomenon, known as ocean acidification...

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...

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...

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...

Coral records of reef-water pH across the central Great Barrier Reef, Australia: assessing the influence of river runoff on inshore reefs

International Atomic Energy Agency (IAEA) Publications

The boron isotopic ($δ$11Bcarb) compositions of long-lived Porites coral are used to reconstruct reef-water pH across the central Great Barrier Reef (GBR) and assess the impact of river...

Influence of glacier melting and river discharges on the nutrient distribution and DIC recycling in the Southern Chilean Patagonia

International Atomic Energy Agency (IAEA) Publications

The Chilean Patagonia constitutes one of the most important and extensive fjord systems worldwide, therefore can be used as a natural laboratory to elucidate the pathway of both organic...

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...

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...
