Ocean Sand, Bahamas

Though the above image may resemble a new age painting straight out of an art
gallery in Venice Beach, California, it is in fact a satellite image of the sands
and seaweed in the Bahamas. The image was taken by the Enhanced Thematic Mapper
plus (ETM+) instrument aboard the Landsat 7 satellite. Tides and ocean currents
in the Bahamas sculpted the sand and seaweed beds into these multicolored, fluted
patterns in much the same way that winds sculpted the vast sand dunes in the Sahara Desert.
