Discovering the Gulf Stream By Sierra

On one of Ben Franklin’s trips across the ocean, he became the first person to study a powerful ocean current called the Gulf Stream. This current could slow down or speed up ships. The Gulf Stream was warmer than the water around it. Ben told sailors all they had to do was put a thermometer into the ocean to find it. Then they will know which way to go.
