As for its possible impacts, they are already being observed in th degradation of shell formation in tiny marine organisms that are a major part of the food chain.

A novel paper by Pierre De Wit from the University of Gothenburg reveals 37 genes correlated with shell formation in the early development of Pacific oysters (Crassostrea gigas).

Finally, in order to understand what functions and genes may be targeted by natural selection in the context of OA, genes involved in the initial phases of shell formation in Pacific oyster (Crassostrea gigas) larvae were identified.

«When CO2 reacts with seawater, the reduction in seawater pH reduces the availability of carbonate ions, which play an important role in shell formation for a number of marine organisms such as corals, marine plankton, and shellfish.

As an associate professor and director of the Okeanos Research Laboratory in Clemson's department of biological sciences, Mount has dedicated his scientific career to studying the mysteries of oyster shell formation and the prevention of marine biofouling by barnacles.

Already, scientists say, ocean acidification may be hindering shell formation by corals and some shellfish.

The experiments were carried out under acidified water conditions to delay the oyster's shell formation process.

That's because the animal doesn't have much protection until it develops its shell and becomes an adult, and acidic conditions could interfere with shell formation (ie - calcification).

Oysters» blood cells (green) ferry raw materials to the site of shell formation.

«When the water is more saturated and has greater alkalinity it helps offset higher levels of carbon dioxide, ensuring that shell formation can proceed — and also making the shells bigger,» Waldbusser says.

To test if the blood cells actually bring the crystals to the site of shell formation, called the mineralization front, the team carved a notch in the shell to induce repair.

Within the field of biology ocean acidification has been shown to adversely impact skeleton and shell formation of a wide range of taxa, sexual reproduction, larval development, metabolism and chemoreception.

The data suggest that the shell formation mechanism can be divided into three different main parts, namely 1) transport of ions across plasma membranes, 2) secretion of shell matrix proteins and 3) production of protease inhibitors.

In particular, if ocean acidity were a problem for shell formation, it would have shown up already in areas where there are naturally high levels of CO2.

The chemical make up of these shells reflect water chemistry at the time of shell formation.
