MODIS image of the Bering Sea, Bering Strait and southern Arctic Ocean acquired 7 May 2000. Image generated from MODIS band 2 (0.85 µm) at 250 m spatial resolution. Detailed structure and leads in the ice pack are apparent. Ice flow from the Bering Strait southward to the Bering Sea is seen in great detail.
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.
