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...

Aragonite saturation state and dynamic mechanism in the southern Yellow Sea, China

International Atomic Energy Agency (IAEA) Publications

Based upon surveys conducted in November 2012 and June 2013, the distribution and dynamics of aragonite saturation state ($Ømega$arag) were investigated in the southern Yellow Sea (SYS)...

High CO2 reduces the settlement of a spawning coral on three common species of crustose coralline algae

International Atomic Energy Agency (IAEA) Publications

Concern about the impacts of ocean acidification (OA) on ecosystem function has prompted many studies to focus on larval recruitment, demonstrating declines in settlement and early growth...

Publications

A “core-top” screen for trace element proxies of environmental conditions and growth rates in the calcite skeletons of bamboo corals (Isididae)

International Atomic Energy Agency (IAEA) Publications

We test for trace element proxies in the high-magnesium calcite fraction of bamboo coral internodes by comparing environmental conditions and growth rates to the specimen-mean...

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...

Publications

Early development of undulated surf clam, Paphia undulate under elevated pCO2

International Atomic Energy Agency (IAEA) Publications

Increasing atmospheric CO2 can decrease the seawater pH and carbonate ions, which may adversely affect the larval survival of calcareous animals. In this study, we simulated future...

Nutrient pollution disrupts key ecosystem functions on coral reefs

International Atomic Energy Agency (IAEA) Publications

There is a long history of examining the impacts of nutrient pollution and pH on coral reefs. However, little is known about how these two stressors interact and influence coral reef...

Publications

Potential future coral habitats around Japan depend strongly on anthropogenic CO2 emissions

International Atomic Energy Agency (IAEA) Publications

Using the results from the NCAR CSM1.4-coupled global carbon cycle–climate model under the Intergovernmental Panel on Climate Change (IPCC) emission scenarios SRES A2 and B1, we estimated...

Publications

Narratives can motivate environmental action: the Whiskey Creek ocean acidification story

International Atomic Energy Agency (IAEA) Publications

Even when environmental data quantify the risks and benefits of delayed responses to rapid anthropogenic change, institutions rarely respond promptly. We propose that narratives...

Isolation of high-level-CO2-preferring Picochlorum sp. strains and their biotechnological potential

International Atomic Energy Agency (IAEA) Publications

Production of CO2-tolerant microalgae have received much attention as well as physicochemical fixation of CO2 in industrial flue gas. Although many microalgae that are tolerant to high...

Publications

Dissolution: the Achilles' heel of the triton shell in an acidifying ocean

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution...

Publications

Effects of elevated pCO2 on the survival, growth, and moulting of the Pacific krill species, Euphausia pacifica

International Atomic Energy Agency (IAEA) Publications

While ocean acidification (OA) is expected to have wide-ranging negative effects on marine species, organisms currently living in variable pH environments that expose them intermittently...

Publications

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...

Marine projections of warming and ocean acidification in the Australasian region

International Atomic Energy Agency (IAEA) Publications

In response to increasing carbon dioxide emissions the oceans have become warmer and more acidic. In this paper, the ability of Earth System Models to simulate observed temperature and...

Global dissolution effects on planktonic foraminiferal Mg/Ca ratios controlled by the calcite-saturation state of bottom waters

International Atomic Energy Agency (IAEA) Publications

Mg/Ca ratios of planktonic foraminiferal tests are important tools for reconstructing past ocean temperatures at different levels of the upper water column. Yet numerous studies suggest a...
