Coral Watch


I recently signed-up with Project Aware Coral Reef Monitoring in behalf of our dive group. Once I receive the free CoralWatch charts from Project Aware, volunteer divers like us can start monitoring the health of the corals during our fun dives anywhere in the Philippines.

The Coral Health Chart was developed by CoralWatch, a non-profit research organization from the University of Queensland, Australia, to involve divers as well as snorkelers, in monitoring coral bleaching and assessing coral health worldwide.

The CoralWatch chart makes monitoring coral reefs easy as it uses a series of colors representing different stages of bleaching and recovery. All you have to do is match the color of the coral with a corresponding color on the chart and record the color code along with the coral type on the data sheet. The data collected is submitted online and analyzed by scientists to answer questions on coral bleaching and recovery patterns as well as the severity and duration of bleaching events.

Due to increasing human activity, the earth’s surface temperature have risen by 1.4 degrees Fahrenheit or 0.8 degrees Celsius, 2005 being the hottest year on record. The rise in water temperature leads to coral bleaching – a process in which the coloration of the corals changes from brown to brilliant white, purple or green.This ‘whitening’ of the coral is due to a loss of the algae living within the tissue of the coral. This loss of the ‘nutrient factory’ in corals may lead to death of the coral or the coral may slowly recover.

Research indicates that more than half of the world’s coral reefs could die in less than 25 years and that almost 30% of the world’s reefs have already died and another 30% severely damaged.

Very little is known about trends of coral bleaching on a global scale. Currently coral health monitoring mainly occurs around a few reefs that are regularly visited by scientists. There are many questions that will have to be answered in order to try and save the reefs. This is where we can help! If many people around the world, will participate in the monitoring program, the scientists will be able to possibly predict which areas will be affected by bleaching, how severe it will be, what is the duration of the bleaching, how long does recovery take, etc.

I can’t wait to go diving again tomorrow… after almost a month and two consecutive deaths in the family that had us shuttling back & forth from Manila to Pangasinan 😦 I desperately need to DIVE and relax …
