Make no bones about ocean acidification

Extra carbon dioxide in the atmosphere is posing a real problem for the world's oceans. It's leading to ocean acidification and coral reefs are the big losers. See how acidification of the water leads to less calcium carbonate, a vital ingredient corals use to build their skeleton. Watch this clip to find out more.

Ocean acidification: what’s happening in our oceans? - practical activity

This practical activity consists of a 'circus' of small experiments on ocean acidification. First, students discover how acids and bases can be identified by systematically testing different substances with universal indicator solution. They then explore what happens to the pH of sea water when they blow carbon dioxide ...

Chemicals on the Great Barrier Reef

This program deals with a range of human impacts on the Great Barrier Reef. Herbicides from land runoff have been traced to algae and sea grasses in river mouths and coastal zones along the Great Barrier Reef. Effects include retardation of photosynthesis and growth of corals. Other pressures on the reef include high water ...
