Resolution

Presently, scientists have additional methods to collect or observe the sea floor. Specially equipped ships like the Resolution can drill holes into the sea floor and retrieve cores of the ocean bottom. These ships also have sonar which can help them look at features in detail. Rocks and other data gathered by the ship have allowed marine scientists to develop a good understanding of the composition and history of the sea floor.

Research submersibles like the Alvin, have been useful in studying the sea floor. These small submarines usually hold only a pilot and one scientist, but can record the ocean bottom through cameras.
