1. What is Oceanography? - Definition, History & Facts
While over 70% of the earth is covered by the oceans, much of it remains a mystery. Its immense size and depth entice scientists to uncover these mysteries. In this lesson, you'll learn about oceanography, the field that studies the world's oceans.
2. The Five Major Oceans: Structure & Properties
In this lesson, you'll take a trip around the world to see each of the five major oceans of planet Earth. You'll learn how you can identify just which ocean you're looking at by noting its general shape and other properties.
3. Oceania Theory: Overview
The Oceania theory says that humanity came to the Americas first by crossing the Pacific Ocean from Australia and the South Pacific islands. Learn why some archaeologists believe this theory shows us how humans discovered the New World.
4. Ocean Exploration & Ancient Greece
The ancient Greeks were innovators in the realm of ocean exploration. Part of that is due to the strides made in navigation and cartography. In this lesson, we'll look at a few of the advances of oceanography in ancient Greece.
5. Mapping the World, Seaborne Commerce & Piracy
This lesson will focus on the improvement of maps, the growth of seaborne commerce, and the piracy that occurred during the Age of Exploration. It will also highlight the famous Sea Dogs of England.
6. James Cook's Contributions to Oceanography
In the 18th century, the Age of Exploration was winding down. But James Cook still managed to change what Europeans knew about the Pacific Ocean. Let's learn about some of his contributions to oceanography.
7. Challenger Expedition: Importance, Goals, & Findings
Today's understanding of the ocean is due to the field of oceanography. But, oceanographic expeditions were once almost unheard of. In this lesson, we'll look at the journey that set the stage for modern oceanography and deep sea exploration: the Challenger Expedition.
8. Modern Ocean Exploration: Technology, Institutions & Research
The world's oceans are sometimes referred to as the last frontier because there is still so much we don't know about it, especially in deep ocean waters. In this lesson, we'll explore the importance of satellites, robots and the rise of institutions in oceanographic research.
