Sea Levels on the Move

Through the use of satellites and land survey tools, scientists are learning about the effects of climate change on our ocean. By combining data regarding sea level and land elevation, they can see how...
Dive through the zones of the ocean to the deep ocean bottom where many strange species live, and there are many yet to be discovered. Explore them in the Deep Ocean Exploration section.

Swimmers brave the waters in the shadow of a coal-fired power plant.  Coal plants like this one emit CO2 into our atmosphere which is warming the planet and altering the chemistry of the ocean.

Climate Change

Today, carbon dioxide (CO2) levels in our atmosphere are the highest they've been in 15 million years. It's the cumulative impact of an ever-expanding population―7 billion people and rising―and an ever-increasing thirst for energy,...

Up Close and Personal With the Fastest Glacier in the World

The Greenland glacier Jakobshavn Isbrae is massive, at around 40 miles long and more than a mile thick. Credit: Nik Gaffney, <a href=" https://www.flickr.com/photos/zzkt/14379937167">Flickr</a> . by Hannah Waters To really see a glacier move,...
On average, Arctic sea ice has decreased by four percent per decade since the late 1970s.

Sea Level Rise

The ocean never stops moving. When you visit the beach, waves roll in and recede and the tides rise and fall. These are small daily changes that balance out over time. But over the...

Climate Change Effects on Glaciers and Ice Sheets

How will changes in temperature affect glaciers and ice sheets? Dr. Sarah Das from the Woods Hole Oceanographic Institution explores this phenomenon first hand in Greenland, where she studies how the melted ice travels...
