A remarkable sight was captured by a fisherman off the coast of Canada in the Labrador Sea, where an iceberg as black as soot was seen floating amidst the pale ice chunks. Hallur Antoniussen, on board the fishing trawler Saputi in mid-May, was amazed by the unusual appearance of the iceberg and shared it on social media.
Describing the iceberg, Antoniussen mentioned to CBC Radio, “I have seen icebergs that are rolled with rocks in them, but this one is completely different. It’s not only black, but it’s almost in a diamond shape.”
While we often picture icebergs as white, they can actually vary in color. White icebergs appear white due to the trapped air pockets scattering light, but as ice becomes more compressed and clear, it can take on different hues. For example, green icebergs contain iron oxides that give them a green tint when mixed with blue ice.
Moreover, icebergs can also have a black or dark gray coloration, often due to dirt or other materials mixing in with the ice. Glaciologist Lev Tarasov suggested that the black iceberg spotted in the Labrador Sea may have originated from a glacier that broke off and fell into the ocean, carrying debris that became uniformly mixed in the ice over time.
Another theory is that the dark coloring could be the result of soot from a volcanic eruption or debris from a meteorite impact. The true origins of the black iceberg may remain a mystery unless similar occurrences are studied up close by scientists in the future.
Regardless of its origins, the black iceberg serves as a reminder of the diverse and fascinating nature of ice formations in our oceans. It is a rare and awe-inspiring sight that captures the imagination of those fortunate enough to witness it.
