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 ...

Lakes in Antarctica

Scientists are not complacent. We still have a lot to learn about the water cycle. The discovery of glacial lakes under the ice in Antarctica actively transporting water between reservoirs was a surprise. These lakes can be up to 3km beneath the ice sheets. The pressure of the ice above helps to melt the ice, forming lakes. ...
