Some beaches are prone to erosion because of the number of homes and hotels built along their shores.
Coral reefs are also very important.
They protect our coastlines, house many underwater plants and animals, and they produce sediment for our beaches. To monitor the health of reefs all over the world, scientists combine remote sensing images with samples of reef collected while scuba diving. Using remote sensing tools provides a quicker and more complete method to collect and compare reef data. Meet the Scientists Chip Fletcher is a coastal geologist that monitors the health of reefs and beaches all over the state. To find out more about what he does click here.
