Conservation in action: here, the buoy team checks in on a mooring buoy in Florida Keys National Marine Sanctuary.
Mooring buoys have been used in the Florida Keys since 1981 as an alternative to anchoring, which can break and damage the coral reef. There are more than 490 mooring buoys in the sanctuary, so the buoy team stays hard at work maintaining them.
