Absolutely, there are icebergs in the Antarctic which sometimes have stripes. These beautiful and striking stripes are formed by layers of snow that react to different conditions. The iceberg pictures with multi-colored banding were taken by a Norwegian sailor named Oyvind Tangen while he was aboard a research trip about 1,700 miles south of Cape Town, South Africa. The expedition came across a number of unusual ice formations. The process that creates these striations was explained by the London Times, “Keith Makinson, of the British Antarctic Survey, said that icebergs that seemed to show stripes were quite common in southern waters, but it was the first time that he had seen the brown stripes. They are believed to be created when ice crystals form under the water and, in a process described as “inverted snow”, rise to stick to the bottom of the ice shelf. As the ice crystals form a new layer at the bottom of the ice shelf, which later fragments to float away as icebergs, tiny particles of organic matter are trapped. Parts of dead marine creatures such as krill form much of the trapped material and have the effect of creating colored stripes, mainly blues and greens, in icebergs.
