Summer safety alert: Swimming in a pool vs. the ocean

GMA headed to the Jersey Shore to highlight the danger in the ocean this summer.

Chief Meteorologist Ginger Zee put on a demonstration to show how swimming in a pool and swimming in open water are two very different things.

First, three college football players and two elite dancers from Temple University were put to the test in a pool.

They had to swim four lengths of a pool -- or a hundred meters -- without touching the bottom.

Then they headed to Ocean City, New Jersey, to do the same distance in the ocean.

They said it was a truly sobering experience.

Experts say they want everyone to see that, as fit as you may be on land, the ocean and other kinds of water are different environments.
