Galapagos Corals May Predict the Future of Reefs Worldwide
Although the corals around the Galapagos Islands are quite scarce, researchers have discovered them and have been using them to direct their research on how coral growth will be affected in the future. A team of researchers with the Khaled bin Sultan Living Oceans Foundation’s Global Reef Expedition, a six-year survey of coral reefs worldwide, spent 18 days aboard the Golden Shadow research vessel in the Galapagos, surveying the corals of eight islands. Along with fascination from the beauty of the Islands, they were able to discover that the amount of CO2 in the water also plays a giant role on coral growth, as well as the temperature changes of the water and the seasons. Derek Manzello, a team member, learns that CO2 conducts a negative effect on coral reefs. CO2 creates acid in the water, and highly acidic water leads to the poor growth of coral reefs. High acidic waters or waters of a very high temperature, cause the symbiotic algae on the reefs to fade creating great damage to the coral reefs. So why does any of this really matter? Well, the answer is simple : You may already know that many organisms in the water rely on coral reefs for shelter or food, but they're also involved in assisting with the reproduction process of an organism. Some organisms, like the Porites lobata, actually release sperm or egg into the water, which then travels to create new coral. Coral reefs have been valuable to our environment for ages. Up till now, scientists believed that coral reefs were tangled in dangerous situations, now they are beginning to uncover the news that there may be a chance for recovery.

This was a fascinating article to read. I never knew that CO2 had such an impact on the growth of coral or the temperature change in the water. I did some research and found that 25% of the coral reefs around the world are gone and 30% are damaged and may be dead soon. Although we can't help the dead coral reefs, it is reassuring to learn that scientists may uncover news on a chance for recovery for the coral reefs that need help.
