Impacts of elevated CO2 on organic carbon dynamics in nutrient depleted Okhotsk Sea surface waters
International Atomic Energy Agency (IAEA) Publications
Increasing CO2 in seawater (i.e. ocean acidification) may have various and potentially adverse effects on phytoplankton dynamics and hence the organic carbon dynamics. We conducted a CO2...

Carbon and nitrogen accumulation in the economic seaweed Gracilaria lemaneiformis affected by ocean acidification and increasing temperature
International Atomic Energy Agency (IAEA) Publications
During mariculture period, maricultured macroalga Gracilaria lemaneiformis experienced seasonal temperature changes. In this study, we examine the effects of predicted ocean acidification...

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)...

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...

Response of subtropical coastal sediment systems of Okinawa, Japan, to experimental warming and high pCO2
International Atomic Energy Agency (IAEA) Publications
Increasing seawater temperatures and CO2 levels associated with climate change affect the shallow marine ecosystem function. In this study, the effects of elevated seawater temperature...

Size-dependent physiological responses of the branching coral Pocillopora verrucosa to elevated temperature and pCO2
International Atomic Energy Agency (IAEA) Publications
Body size has large effects on organism physiology, but these effects remain poorly understood in modular animals with complex morphologies. Using two trials of a ∼24 day experiment...

Ocean acidification has lethal and sub-lethal effects on larval development of yellowfin tuna, Thunnus albacares
International Atomic Energy Agency (IAEA) Publications
Ocean acidification (OA), the process by which increasing atmospheric CO2 is absorbed by the ocean, lowering the pH of surface waters, has been shown to affect many marine organisms...

Insights from sodium into the impacts of elevated pCO2 and temperature on bivalve shell formation
International Atomic Energy Agency (IAEA) Publications
Ocean acidification and warming are predicted to affect the ability of marine bivalves to build their shells, but little is known about the underlying mechanisms. Shell formation is an...

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...

Combined effects of short-term exposure to elevated CO2 and decreased O2 on the physiology and energy budget of the thick shell mussel Mytilus coruscus
International Atomic Energy Agency (IAEA) Publications
Hypoxia and ocean acidification are two consequences of anthropogenic activities. These global trends occur on top of natural variability. In environments such as estuarine areas, short-...

Detrimental effects of reduced seawater pH on the early development of the Pacific abalone
International Atomic Energy Agency (IAEA) Publications
The hatching process of the Pacific abalone Haliotis discus hannai was prolonged at a pH of 7.6 and pH 7.3, and the embryonic developmental success was reduced. The hatching rate at pH...
