What Causes the Stripes in Icebergs?
striped icebergs are created through the interplay of temperature, water, and trapped sediment over long periods. As snow accumulates, freezes, and compresses, layers form within the ice. Variations in the conditions at the time of freezing create these captivating streaks of different shades:
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.The Beauty and Fragility of Striped Icebergs
Striped icebergs are not just visually stunning—they offer a glimpse into the complex processes happening in polar climates. Because they originate from glaciers that drift into the ocean, these icebergs carry a record of environmental changes. However, their existence is fleeting. Warmer temperatures and ocean currents quickly erode them, making each sighting a rare and treasured moment.
Phenomena: This stripy iceburg was pictured in the Skaftafell National Park in south central Iceland. These black stripes were likely caused by sediment as the berg slid downhill towards the sea.
Resembling strange creatures from the deep, rare striped icebergs are occasionally seen.
Norwegian sailor Oyvind Tangen, 62, was on board the research ship G O Sars when he photographed this unusual ice formation, floating a few miles off the coast of the frozen continent.
striped icebergs are created through the interplay of temperature, water, and trapped sediment over long periods. As snow accumulates, freezes, and compresses, layers form within the ice. Variations in the conditions at the time of freezing create these captivating streaks of different shades:
- Blue Stripes: Occur when the ice forms without air bubbles, resulting in a deep blue color due to the absorption of red light.
- Green Stripes: Form when the iceberg absorbs algae-rich seawater, giving it an emerald tint.
- Brown or Yellow Stripes: These occur when dust and sediment are trapped between layers during formation.
