Publications

Reconstructing aragonite saturation state based on an empirical relationship for Northern California

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is a global phenomenon with highly regional spatial and temporal patterns. In order to address the challenges of future ocean acidification at a regional scale, it is...

Publications

Water flow modulates the response of coral reef communities to ocean acidification

International Atomic Energy Agency (IAEA) Publications

By the end of the century coral reefs likely will be affected negatively by ocean acidification (OA), but both the effects of OA on coral communities and the crossed effects of OA with...

Publications

Effects of ocean acidification on sperm motility in the red abalone, Haliotis rufescens

International Atomic Energy Agency (IAEA) Publications

Fossil fuel emissions are changing global temperature and ocean water chemistry. These changes are already altering the seasonal upwelling events that bring deeper ocean water with lower...

Publications

Effects of ocean acidification caused by rising CO2 on the early development of three mollusks

International Atomic Energy Agency (IAEA) Publications

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

Publications

Deep oceans may acidify faster than anticipated due to global warming

International Atomic Energy Agency (IAEA) Publications

Oceans worldwide are undergoing acidification due to the penetration of anthropogenic CO2 from the atmosphere1,2,3,4. The rate of acidification generally diminishes with increasing depth....

Publications

Decadal variability in seawater pH in the West Pacific: Evidence from coral $δ$ B-11 records

International Atomic Energy Agency (IAEA) Publications

Long-term seawater pH records are essential for evaluating the rates of ocean acidification (OA) driven by anthropogenic emissions. Widespread, natural decadal variability in seawater pH...

Publications

Use of a Free Ocean CO2 Enrichment (FOCE) system to evaluate the effects of ocean acidification on the foraging behavior of a deep-sea urchin

International Atomic Energy Agency (IAEA) Publications

The influence of ocean acidification in deep-sea ecosystems is poorly understood, but is expected to be large owing to the presumed low tolerance of deep-sea taxa to environmental change....

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...

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...

Publications

Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes

International Atomic Energy Agency (IAEA) Publications

Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms,...

Publications

Ocean warming and acidification have complex interactive effects on the dynamics of a marine fungal disease

International Atomic Energy Agency (IAEA) Publications

Diseases threaten the structure and function of marine ecosystems and are contributing to the global decline of coral reefs. We currently lack an understanding of how climate change...
