Despite the names "Atlantic" and "Pacific," the ocean is one giant interconnected ecosystem. Learn about the systems that hold it together, from sea ice and volcanoes to currents and chemistry.

  • The earth's climate is changing – and it's causing sea levels to change too. Even small changes in sea levels can dramatically alter coastal landscapes all across the world.

    Hydrothermal Vent Creatures

  • <p>On <strong><a href="http://earthquake.usgs.gov/earthquakes/eqinthenews/2011/se082311a/#summary">August 23, 2011 a 5.8 earthquake</a></strong> emanated from the little-known Central Virginia Seismic Zone. The epicenter was near Mineral, VA, but the tremor shook homes, schools, and office buildings in Washington, DC and beyond. In this brief video, Smithsonian educator Catherine Sutera uses a Slinky® to demonstrate two types of seismic waves that people in the area may have felt: the <strong><a href="http://earthquake.usgs.gov/learn/glossary/?term=P%20wave">P wave</a></strong>&nbsp;and the <strong><a href="http://earthquake.usgs.gov/learn/glossary/?term=S%20wave">S wave</a></strong>. Both are known as "body waves," because they move through the planet's interior. The P wave, also called the primary wave, is the fastest seismic wave. But it's the S wave that creates much of the above-ground shaking during an earthquake.    You can learn about body waves and the more complicated surface waves on <strong><a href="http://www.edcenter.sdsu.edu/ssc/3d/ssc3dproject.html">Michigan Tech's Geological and Mining Engineering and Sciences website</a></strong>.
