Oceanography

Oceanography is the study of the oceans as ecological systems. In this section, learn about topics like currents, deep-sea research or how rogue waves work.


How Desalination Works

Very little of the world's water is usable because of its high salt content, but a process known as desalination may help change that. How does desalination work to turn salt water into fresh water?

Is the Dead Sea really dead?

The Dead Sea is host to tourists who visit in droves to soak in its mineral-rich waters. Is the saltiest body of water in the world about to dry up?

Who owns the oceans?

Early explorers drove flags into the ground to claim territories. But no one bothered to float a flag in the oceans. For the most part, we peaceably shared the oceans until we realized what valuable goods could be found in their dark and murky depths.

How can you make water invisible?

It's colorless, odorless and definitely life-sustaining, but is it invisible to the naked eye? Not usually. So what's going on with everyone's favorite liquid?

How Wave Energy Works

Rough times call for creative measures. The world is filled with oceans, and oceans are filled with wave energy that could potentially be transformed into power. Is wave energy a viable fossil fuel alternative?

How Hydrology Works

Without water, Earth would be a barren and lifeless planet. But did you know the Earth's water supply has not increased or decreased for billions of years? No wonder hydrologists are so fascinated by water.

Ocean Conservation Pictures

Ocean conservation has been a popular topic in many environmental debates recently. This collection of pictures show just why ocean conservation is so important.

Ocean Current Pictures

Ocean currents can have an incredible impact on Earth's weather. This gallery of images shows how powerful ocean currents can be in the environment.

What are tide tables?

Whether you sail, surf, fish or collect shells, having one of these could help you out before you hit the water.

How Ocean Currents Work

You might never notice the relentless movement of the oceans unless their waters went eerily still. What forces drive the oceans every second of the day?
