With their bizarre black, blue and even green stripes - some of these beautiful icebergs could pass for man-made works of art instead of simple quirks of nature.
From the Arctic Circle in the north to Antarctica in the south, the colourful lines and veins in their ice are formed by frozen melt water, sediment and even algae combined with huge pressures.
The blue stripes are created when gaps in the icebergs fill with melt water which freezes, while green veins are left when seawater rich with algae freezes to the bottom of the bergs.
这些黑色、蓝色甚至是绿色条带状的冰山,就是大自然的鬼斧神工,堪比人类艺术品
Stripey: This spectacular iceberg in the Jokulsarlon lagoon, Iceland, looks like it has had stripes dyed into it, but they are a completely natural phenomenon
