The rising level of carbon dioxide in the atmosphere is making the world's oceans more acidic. Jacqueline Ruttimann reports on the potentially catastrophic effect this could have on marine creatures.

Impact of near-future ocean acidification on echinoderms

It is hypothesized that populations/species naturally exposed to variable environmental pH conditions may be pre-adapted to future OA highlighting the importance to understand and monitor environmental variations in order to be able to to predict sensitivity to future climate changes.

Patterns of magnesium content in Arctic bryozoan skeletons along a depth gradient

The bryozoan results suggest that ocean acidification may have less impact on the studied bryozoans than is generally assumed, and exemplifies quantitative testing of spatial patterns of skeletal geochemistry for predicting the biological effects of environmental change in the oceans.

Corrosion of Snails in H2CO3 Medium and Their Protection by Aloe Vera

Snails are beautiful creation of nature. They occur in rivers as well as ponds. But these sources of water are contaminated by effluents, pollutants, acid rain, particulates, biological wastes etc.

Recurrent breakdown of Late Permian reef communities in response to episodic volcanic activities: evidence from southern Guizhou in South China

Reefs, both living and ancient, are extremely sensitive to environmental change. Recurrent breakdown of reef communities implies episodic occurrence of unfavorable marine conditions. An alternating

Role of abiotic factors in enhancing the capacity of mangroves in reducing ocean acidification

The present study investigated the effects of rising carbon dioxide levels in nature and the carbon sequestration potential of dominant mangrove species for reducing the toxic effects of ocean

Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms

13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.

Oceanic phytoplankton, atmospheric sulphur, cloud albedo and climate

The major source of cloud-condensation nuclei (CCN) over the oceans appears to be dimethylsulphide, which is produced by planktonic algae in sea water and oxidizes in the atmosphere to form a

Will human-induced changes in seawater chemistry alter the distribution of deep-sea scleractinian corals?

The answer to the title question is uncertain, as very few manipulative experiments have been conducted to test how deep-sea scleractinians (stony corals) react to changes in seawater chemistry.

Effect of increased atmospheric CO2 on shallow water marine benthos

[1] The decision to sequester CO2 in the deep ocean should ultimately be based not only upon what would happen to deep sea marine biota but also upon what would happen to surface organisms if nothing

Climate sensitivity to ocean dimethylsulphide emissions

The production of dimethylsulphide (DMS) by ocean phytoplankton is hypothesized to form part of a feedback process on global climate. Changes in the DMS flux to the atmosphere cause changes to

Reduced calcification of marine plankton in response to increased atmospheric CO2

It is suggested that the progressive increase in atmospheric CO2 concentrations may slow down the production of calcium carbonate in the surface ocean, as the process of calcification releases CO2 to the atmosphere.

Modern‐age buildup of CO2 and its effects on seawater acidity and salinity

The impacts of increases in atmospheric CO2 since the midst of the 18th century on average seawater salinity and acidity are evaluated. Assuming that the rise in the planetary mean surface

Oceanography: Anthropogenic carbon and ocean pH

It is found that oceanic absorption of CO2 from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years.
