How do we monitor the health of coral reefs?

    According to The NOAA (National Oceanic and Atmospheric Administration)’s Coral Reef Conservation Program, it involves “monitoring, mapping, and assessing.” They use satellites to monitor heat of the reefs, which lets scientists and researchers know if the reef is at risk for coral bleaching. Coral bleaching can cause severe damage to the reefs themselves and the marine life that dwell within them. The program also uses instruments that measure wind speed/direction, gusts, air temperature, pressure, and light.

    Many times, when coral reefs die out, it is the result of bleaching. Bleaching occurs when aspects of the reef environment endure stress, such as changing ocean temperatures, and the coral lose their symbiotic microalgae. Scientists monitor coral and the presence, or lack of presence, of bleaching by using spectroraiometers to measure the amount of light that is reflected by the coral. The more light that is reflected, the more microalgae, thus the healthier the coral. Scientists also measure growth patterns, and study the water for contaminants.
