A recent study published in Environmental Science and Technologyhas revealed a new strategy for preserving the world’s coral reefs: blowing bubbles. Scientists at Stanford have discovered that by pumping bubbles through coral reefs at certain hours of the day, they are able to release excessive concentrations of carbon dioxide trapped in coastal marine environments. This is good news for coral reefs- which have become increasingly vulnerable to acidity in the water caused by high levels of carbon dioxide.
The study, titled “Bubble Stripping as a Tool To Reduce High Dissolved CO2 in Coastal Marine Ecosystems,” said the concentrations of carbon dioxide found in coastal ecosystems are by human-induced eutrophication. This leads to the high acidity level of water that is well beyond the tolerance of the organisms.
Co-author and earth science professor Rob Dunbar said that the “bubble pulse method” can help us bring the reefs to conditions 100 years ago, and even to the environment that they have “adapted for many thousands of years.”
