Messina Strait, Italy
4000 x 6000 61 MB - GeoTIFF
Between the island of Sicily and mainland Italy runs a narrow strip of water, the Messina Strait. The Messina Strait’s strong currents can rip seaweed from the ocean floor. The main current runs from south to north, but a smaller current runs in the opposite direction. The currents alternate about every six hours, and the strait’s complicated wave patters can be seen from space.

To the untrained eye, Antarctica may look like a giant piece of solid ice that rarely changes, but scientists studying the continent have long known better. The icy surface is dynamic, with glaciers and "streams" of ice flowing toward the ocean.
