Underwater- Remotely Operated Vehicles - Episode 210



How healthy are two coral reefs?
We're Chris, Cory, Nikki, and Bruce, and we want to get to the bottom of things. Especially the ocean! We built an ROV, which stands for Remotely Operated Vehicle, and we use it to explore underwater. We control it from a boat on the surface, while it dives deep into the sea. It has an onboard video camera that sends pictures back to us on the boat. We live near the coast of Florida, and we were curious about how healthy the coral reefs are. Our question: How can we use our ROVs to determine the health of the coral reef?

How would you investigate this question?
How would you investigate this question? So if the ROV is going to do the diving for you, you still have to think about what you are going to look for. How can you tell a healthy coral from a diseased one just by looking? A reef can extend for miles, so you'll have to decide how much of the reef to look at. Think about other factors, too, such as how close the reef is to sources of pollution, or whether the reef gets a lot of boat traffic. Describe your investigation in your notebook and discuss it with your teacher, or go to ROV to learn what Chris, Cory, Nikki, and Bruce discovered.
