Ocean acidification and carbon dioxide absorption

Many sea creatures such as crabs and shell fish are affected greatly by the levels of acid and temperatures of the ocean they live in as it prevents their outer shell development. This can lead to a depletion in numbers and a knock on effect along the food chain.

These resources include practical activities that model the effects of temperature and acid levels upon carbon dioxide absorption on a small scale in the laboratory situation rather than in the ocean. The first looks at how temperature increases will decrease carbon dioxide absorption, and the second in a similar way explores how changes in acidity also affects the absorption.
