The ‘smell’ of coral as an indicator of reef health

Source: Science Daily

A study conducted in the southern Great Barrier Reef reveals the chemical diversity of emissions from healthy corals. The researchers found that across the reef-building coral species studied on Heron Island, the abundance and chemical diversity of their gas emissions fell significantly during heat stress experiments. With the increasing frequency of heat stress events, understanding coral emissions may prove to be a key reef conservation tool.
