The Ocean Exploration Quiz – Exploring the Last Frontier

The ocean covers most of Earth, yet it is less explored than the surface of the Moon in some ways. Modern oceanography began with the HMS Challenger expedition in the 1870s, which sampled the seafloor and discovered thousands of species.

The 1900s brought new tools. William Beebe descended in a bathysphere, Jacques Cousteau co-invented the Aqua-Lung and the Trieste reached the deepest point. Submersibles like Alvin discovered hydrothermal vents and explored the Titanic.

Today robots, autonomous vehicles and sonar map and study the deep. Explorers like Sylvia Earle campaign to protect the ocean as we learn more about it.
