Georgia's artificial reefs create underwater oases from old bridges, tanks and subway cars

There is a lot of junk piled in the ocean off of Georgia’s coast, including battle tanks, World War II cargo ships and New York City subway cars.

These aren’t gigantic pieces of litter. They’ve been put there on purpose over the past 50 years to host more habitat for marine creatures and create more good fishing spots for anglers.  

Since the program began, though, mapping tools have improved, and Georgia’s dynamic coastline and weather have shifted things around. So recently, Georgia scientists set out to create a better map of the state’s artificial reefs.
