In the frigid waters of the North Atlantic, icebergs are a common sight. However, among the usual white glacial giants, one particular iceberg caught the attention of a fisherman.

Hallur Antoniussen, a fisherman from the Faroe Islands, was on a fishing trawler when he spotted the unusual black iceberg last month. The iceberg, roughly six kilometers away, appeared massive and uniquely shaped.

Icebergs are typically white due to trapped air pockets scattering light. However, this black iceberg's coloration is believed to be a result of mixing with debris thousands of years ago when it was part of a larger glacier.

Dr. Lev Tarasov, a glaciologist from Memorial University in Canada, explained that the iceberg may have rolled over, revealing its underbelly. As it melts while traveling around Baffin Bay and down the coast of Labrador, the clean ice underneath becomes visible.

Experts suggest that the dirt on the iceberg may have been hidden from light for hundreds of thousands of years. Another theory is that the dark coloration could be due to mixing with soot from a volcanic eruption or debris from a meteor strike.

While smaller black icebergs were observed in Greenland last summer, none were as remarkable as the one discovered off the coast of Canada.
