Opuhala was the ancient Hawaiian goddess of corals and spiny creatures. The National Oceanic and Atmospheric Administration (NOAA) Coral Health & Monitoring Program has chosen this name to represent the project to study the influence of fluctuating sea temperatures on the growth and health of corals around the world, and also to compare the in situ data with satellite-measured data in an effort to improve satellite algorithms. Three different types of coral reefs: fringing, barrier, and atolls will be monitored at 5m, 10m and 15m depths, where appropriate.
The sea temperature sensor developed for the Opuhala project has been developed with low cost in mind because of the diversity of sites that will measure sea temperature in this global project.
