Elevated seawater CO2 concentrations impair larval development and reduce larval survival in endangered northern abalone (Haliotis kamtschatkana)

International Atomic Energy Agency (IAEA) Publications

Increasing levels of anthropogenic carbon dioxide in the world's oceans are resulting in a decrease in the availability of carbonate ions and a drop in seawater pH. This process, known as...

The effect of pH on natural settlement and metamorphosis in the invasive limpet, Crepidula fornicata

International Atomic Energy Agency (IAEA) Publications

The average pH of ocean surface waters has dropped by about 30%, due to absorption of anthropogenic CO2 emissions. In the past decade, much research has been conducted examining the...

Relationships between temperature, pH, and crusting on Mg/Ca ratios in laboratory-grown Neogloboquadrina foraminifera

International Atomic Energy Agency (IAEA) Publications

Mg/Ca ratio paleothermometry in foraminifera is an important tool for the reconstruction and interpretation of past environments. However, existing Mg/Ca:temperature relationships for...

Publications

Laboratory simulation reveals significant impacts of ocean acidification on microbial community composition and host-pathogen interactions between the blood clam and Vibrio harveyi

International Atomic Energy Agency (IAEA) Publications

It has been suggested that climate change may promote the outbreaks of diseases in the sea through altering the host susceptibility, the pathogen virulence, and the host-pathogen...

Different calcification responses of two hermatypic corals to CO2-driven ocean acidification

International Atomic Energy Agency (IAEA) Publications

Understanding how calcification is influenced by the enhanced dissolution of CO2 in the oceans is the key to evaluating the effects of ocean acidification (OA) on coral reefs. In this...

Ocean acidification increases the accumulation of toxic phenolic compounds across trophic levels

International Atomic Energy Agency (IAEA) Publications

Increasing atmospheric CO2 concentrations are causing ocean acidification (OA), altering carbonate chemistry with consequences for marine organisms. Here we show that OA increases by...

Effects of increased seawater pCO2 on early development of the oyster Crassostrea gigas

International Atomic Energy Agency (IAEA) Publications

This study demonstrated that the increased partial pressure of CO2 (pCO2) in seawater and the attendant acidification that are projected to occur by the year 2300 will severely impact the...

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...

Origin and dynamics of dissolved organic matter in a mariculture area suffering from summertime hypoxia and acidification

International Atomic Energy Agency (IAEA) Publications

Based on six cruises from March to September in 2016, we investigated monthly distributions of dissolved organic matter (DOM) and ancillary water chemistry parameters in a mariculture...

Publications

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...

Ocean acidification affects the cytoskeleton, lysozymes, and nitric oxide of hemocytes: a possible explanation for the hampered phagocytosis in blood clams, Tegillarca granosa

International Atomic Energy Agency (IAEA) Publications

An enormous amount of anthropogenic carbon dioxide (CO2) has been dissolved into the ocean, leading to a lower pH and changes in the chemical properties of seawater, which has been termed...
