Blue iceberg observed by tourists along the coast of Alaska, 2010. A blue iceberg is visible after the ice from above the water melts, causing the smooth portion of ice from below the water to overturn. [1] [2] The rare blue ice is formed from the compression of pure snow, which then develops into glacial ice. [3] [4]
The blue colour will not be seen again until the ice breaks or turns over to expose ice which air could not reach. For example, lucky tourists at Tasman Glacier, New Zealand in January 2011 saw an iceberg roll over to reveal startling blue ice, kept from air by staying underwater for months since the iceberg calved.

A blue-ice area in the Miller Range with a meteorite. A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface.
An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
The iceberg, which measures about 61 by 59 kilometers (about 37.9 by 36.7 miles), is slightly smaller than the mountain and is “at that sweet spot in size, where it’s retained by the column ...
The world's biggest iceberg is on the loose and is threatening to collide with a tiny south Atlantic island, potentially affecting the wildlife there, scientists warned this week. Known as A23a ...
It might seem like a simple question. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same ...
convincing him that global warming is happening and “humans are almost entirely the cause.” 1 Based on Dr. Muller’s evidence and the views of virtually all climate scientists, I am writing to inquire about the influence of these findings on your previously expressed skepticism about climate change.
