Earth’s newest babies!
Our planet is full of fascinating surprises and mother earth can often astonish us by dishing up something new just when we think we know it all. In a recently conducted global survey of barrier islands using satellite images, two US researchers have found that the Earth has 657 more barrier islands than previously discovered.
Barrier islands are narrow strips of sand, often spits or sandbars that grow into full-blown, vegetated islands. The image shows previously unrecognised barrier islands along the northeast coast of Brazil.
The islands are found along the edge of every continent except Antarctica, and in 2011 scientists and naturalists are still finding new ones. The latest survey puts the number of barrier islands at 2,149 worldwide, 657 more than the 1,492 islands that had been identified in a 2001 survey.
