Watch: Joanna Steidle’s footage reveals an underwater world hidden just out of sight.

Joanna Steidle, 50, grinned as she launched her drone over the Atlantic Ocean on a hazy July morning. She was on the lookout – for sharks.
A native of Southampton, New York, Ms Steidle grew up going to the beach, longing to learn more about what lived beneath the surface. Everything changed when she picked up a drone in 2015.
