The EarthObserver app puts a worldwide interactive atlas at your fingertips and lets you explore the Earth like never before. Created at Columbia University and supported by the U.S. Science Foundation, EarthObserver allows you to zoom in on ocean floor beds and deep-sea canyons, see ripple marks in a New York harbor, determine the eruption history of a volcano and observe Arctic ice cover across changing months and seasons.

The app also includes comprehensive U.S. maps useful for planning your next hike. EarthObserver’s data is updated monthly from satellites, research ships and other sources. The app “gives you a tactile experience of touching the earth that results in a real retention of information,” says William Ryan, a marine geologist at Columbia University.
