A photographer captured what is not normally seen: 90% of the submerged mass of a block of ice
Images taken by photographer and filmmaker Alex Cornell reveal what is usually kept hidden: 90% of the submerged mass of an iceberg.
In an expedition to Antarctica, Cornell documented the iceberg called Alley, located in a region in the west of the Weddell Sea, which remained overturned, free of snow and debris, revealing a polished, almost translucent blue surface.
“Before we arrived, the cove was full of icebergs,” Cornell told HuffPost Arts & Culture , “but this was the only one that had that jade color so pure and that texture so clean.”
The salt water is denser than the sweet, which helps these ice giants float in the sea. However, as they melt, their weight distribution may change, allowing rotation.
According to the National Ice and Snow Data Center in the United States , glacial ice is usually blue when very dense thanks to several years of compression. “When the ice becomes extremely dense, it absorbs a small amount of red light, leaving a blue tint in the reflected light, which is what we see. When the glacial ice is white, it means that there are still many small bubbles in the ice, “explained the website.
