Open Source Temperature Sensors for Coral Reefs

Opuhala Sea Temperature Sensor

Opuhala was the ancient Hawaiian goddess of corals and spiny creatures. We have chosen this name to represent our 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 depth, where appropriate.

The sea temperature sensor developed for the Opuhala project has been developed with low cost in mind because of the many sites that will be measuring sea temperature in this global project.
