Rising carbon dioxide in the atmosphere is causing ocean acidification, leading to adverse impacts on shell-forming organisms such as sea urchins, cold water corals and plankton.
Ocean acidification, caused by increasing amounts of atmospheric carbon dioxide dissolving in the ocean, poses a serious threat to marine ecosystems.
Increasing acidity affects the ability of some planktonic organisms to form shells, and is expected to change the species composition of plankton, with flow-on effects to higher levels of the food web.
Thermometer-based climate records started in 1850, so scientists have gone “back to nature” for sources of long-term climatic information to help them better understand climate change and rising sea levels.
RMIT University researchers have used nanotechnology to create a pioneering sensor that can precisely measure one of the world’s most poisonous substances—mercury.
The mercury sensor developed by RMIT’s Industrial Chemistry Group uses tiny flecks of gold that are nano-engineered to make them irresistible to mercury molecules.
