Our beautiful planet: Amazing Icebergs
A series photos featuring strikingly beautiful and unusual icebergs…Posted Mar 1, 2010
It’s easy to think of icebergs as large chunks of white glacier ice floating on cold grey seas, impressive by their size and varied shapes, but otherwise unremarkable to the casual observer. But as with all aspects of nature’s design, beauty and interest unfold in continuing layers as we look within. The images below, untouched by photo editing, reveal remarkable patterns and features within icebergs which are striking in their beauty while also telling a story of geology, history and climate to the curious eye.

In the Antarctic region, icebergs sometimes have stripes, formed by layers of snow that react to different conditions. When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.
Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form.
In the cold Antarctic region, water freezes the instant it comes in contact with the air. The temperature of the water is already some degrees below freezing. Here we see a wave froze in mid-air!
These marvelous creations stun us with their simple visual beauty, and inspire us to be caring stewards of our natural environment.
