Derek Manzello is the coordinator of NOAA’s Coral Reef Watch, the United States agency programme that monitors coral reef ecosystems worldwide using satellite data and environmental observations. He works on tracking coral bleaching events, ocean temperature patterns and the health of reef systems under climate stress.
Coral Reef Watch provides early warning systems for mass bleaching events, which occur when prolonged warm water temperatures force corals to expel their symbiotic algae. Manzello’s work helps scientists, managers and conservationists respond to threats in near real time, supporting decision-making for reef protection across tropical and subtropical waters.
