Southern Brazil Atlantic Coastline • • Earth Image Gallery

Southern Brazil Atlantic Coastline is seen here in this Image of the Day from the NASA Earth Observatory and features a look at the Atlantic coastline of southern Brazil. The tan formations are the Barchan dunes, which separate the ocean coastline from Lagoa de Barros, one of several lagoons formed hundreds of thousands of years ago when the sea level was much higher. This image was captured by an astronaut on board the International Space Station.
