NASA Images Reveal Curious Colors in Antarctic Ice

Satellite imagery captures flipped icebergs in stunning blues and greens, along with a penguin colony's surprising signature.

In a display of nature's palette, NASA has released satellite imagery capturing colorful icebergs near the Amery Ice Shelf in east Antarctica.The vibrant blues, greens and even yellowish tones in the icebergs stand out against the white expanse of snow and sea ice, offering a rare glimpse of the region's dynamic ice features.The image, taken on October 26 by the Operational Land Imager-2 aboard Landsat 9, reveals flipped icebergs exposing their snow-free undersides.

The iron-rich icebergs, formed in specific conditions under the Amery Ice Shelf, act as carriers of essential nutrients. As they drift and melt, they transport iron from the land to the sea.These vibrant colors are visible only when icebergs overturn, a phenomenon triggered by melting or breaking that makes them unstable. Helicopter surveys in the area have revealed a high proportion of overturned icebergs, making this region particularly notable for its colorful ice displays.
