EXPLORING THE OCEAN FLOORS
The HMS Challenger circumnavigated the world from 1872 - 72 in the first major scientific study of the oceans.

In the 1960s, Cousteau developed habitats so “aquanauts” could stay underwater for weeks. His 1964 film “World Without Sun” won an Academy Award.

The gravity piston corer has long been one of the basic tools used to collect samples of the sediments covering the sea bottom. “Doc” Ewing required all Lamont vessels to collect at least one core each day, a practice still followed.
Lamont’s Deep-Sea Sample Repository houses the greatest collection of materials retrieved from the ocean floors.
The Glomar Challenger was the first successful deep-sea drilling ship.
The JOIDES Resolution carries on today with an ambitious deep-sea drilling program.

Background Information
Balloons rapidly gained popularity and uses in the 19th century
The first heavier-than-air flight was achieved by the Wright Brothers
Also earlier in the 20th century, Robert Goddard began to develop the first successful rockets
Artificial Satellites
Today, satellite images are routinely seen.
For more detailed studies, we use “polar-orbiting” satellites
