DIC is based on the total amount of carbon dioxide in seawater. Total alkalinity is a measurement of the water’s ability to resist change in pH, which depends on the concentration of all alkaline ...

Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water's pH, making the ocean more acidic. Carbon dioxide is ...

Earth's oceans are changing due to rising levels of carbon dioxide in the atmosphere. Museum palaeontologist Prof Richard Twitchett explains, 'Ocean acidification is a change in the pH of seawater, ...

What is the 'other carbon dioxide problem'? How are humans driving changes in the chemistry of the ocean, and what might this mean for marine ecosystems in the future?

Through one of the primary carbon storage mechanisms, the biological carbon pump, phytoplankton (microscopic marine plants at the bottom of the oceanic food chain) take up CO 2 in the surface ocean ...

Carbon dioxide is made up of one carbon atom covalently bonded to two oxygen atoms. Although electrons are shared, they are not shared equally between the carbon and the oxygen atoms. The oxygen atom ...

Carbon dioxide, along with oxygen, is one of principal gases dissolved in water sources. In fact, CO 2 is roughly 200 times more soluble than oxygen and can therefore enter liquids much more easily.

Carbon dioxide ... layers of the ocean as primary producers are eaten by other organisms, which themselves reproduce, generate waste and die. Some plankton combine calcium and dissolved carbonates ...

But that has led to ocean acidification. "When carbon dioxide from the atmosphere dissolves into the ocean, it decreases the pH, leading to ocean acidification," Hauri said. "These conditions make ...
