They can learn about changes in organic productivity, climate, and other ocean phenomena going back more than 150 million years.
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.

For the same reason they are in no other ocean, there is no requirement for them.
Floating markers in the ocean are called buoys.

Scientists can tell when an El Nino will occur if in the tropical Pacific Ocean, a network of buoys will indicate a change in temperature, currents and winds in the equatorial band. These collected data are evaluated by a computer designed to predict El Nino.

When sailing the ocean blue, buoys are an invaluable tool. They assist in navigation by directing ships into shipping channels and away from shoals or crowds.
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
