A black iceberg photo has gone viral after a user posted it to Reddit. Many are amazed by the off colored ice block.
Reddit user Rundboll posted a photo of the rare black iceberg on Friday. The post made it to the front page of Reddit and received over 1,200 comments. Rundboll did not give any information or background on the image, but one user found an explanation on The Canadian Encyclopedia.
The section called appearance reads:
"Most icebergs are white except along freshly calved ice cliffs, which tend to appear blue. Others may appear green, brown or black, or combinations of these colours. These icebergs have usually rolled over, exposing basal ice, or have emerged from below water level. The various colorations are caused by differences in density, air-bubble content and impurities. For example, black ice is of high density and bubble free; dark layers indicate the presence of rock materials derived from the base of the parent glacier. Occasionally, rocks may be found on the original upper surface of the iceberg. As the iceberg melts, these materials precipitate into marine or lake sediments."
Some other users posted photos of very blue icebergs and some got creative. One user suggested that they had a photo of a green iceberg. The photo was a head of iceberg lettuce. Another said they had a photo of an ice cube, which turned out to be rapper Ice Cube's head on water.
