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...

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...

Publications

Boosted nutritional quality of food by CO2 enrichment fails to offset energy demand of herbivores under ocean warming, causing energy depletion and mortality

International Atomic Energy Agency (IAEA) Publications

The CO2-boosted trophic transfer from primary producers to herbivores has been increasingly discovered at natural CO2 vents and in laboratory experiments. Despite the emerging knowledge...

Publications

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...

Publications

Predicted impact of ocean acidification on a marine invertebrate: elevated CO2 alters response to thermal stress in sea urchin larvae

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) and the biological consequences of altered seawater chemistry have emerged as a significant environmental threat to healthy marine ecosystems. Because a more...

Publications

Coral reefs and people in a high-CO2 world: where can science make a difference to people?

International Atomic Energy Agency (IAEA) Publications

Reefs and People at Risk Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key...

Effect of pH and temperature on antioxidant responses of the thick shell mussel Mytilus coruscus

International Atomic Energy Agency (IAEA) Publications

This study evaluated the combined effects of seawater pH decrease and temperature increase on the activity of antioxidant enzymes in the thick shell mussel Mytilus coruscus, an ecological...

An aposymbiotic primary coral polyp counteracts acidification by active pH regulation

International Atomic Energy Agency (IAEA) Publications

Corals build their skeletons using extracellular calcifying fluid located in the tissue-skeleton interface. However, the mechanism by which corals control the transport of calcium and...

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...

Ecological effects of ocean acidification and habitat complexity on reef-associated macroinvertebrate communities

International Atomic Energy Agency (IAEA) Publications

The ecological effects of ocean acidification (OA) from rising atmospheric carbon dioxide (CO2) on benthic marine communities are largely unknown. We investigated in situ the consequences...

Symbiodinium mitigate the combined effects of hypoxia and acidification on a non-calcifying cnidarian

International Atomic Energy Agency (IAEA) Publications

Anthropogenic nutrient inputs enhance microbial respiration within many coastal ecosystems, driving concurrent hypoxia and acidification. During photosynthesis, Symbiodinium spp., the...

Perceptions of climate change and adaptation responses in a local community: the Barwon Estuary Complex, Victoria

International Atomic Energy Agency (IAEA) Publications

The climate change focus in Australia has shifted from mitigation to adaptation with an emphasis on place-specific case studies. The Barwon Estuary Complex (BEC) on the Bellarine...
