The Pine Island Glacier or PIG is a giant ice steam that is considered to be the world's most rapidly shrinking glacier on Earth. Scientists predicted that the PIG will give birth to large icebergs every six to ten years. The latest progeny is a 700-sq km (270 sq miles) iceberg that chipped from the PIG in July.
Now scientists are worried about the Singapore-sized iceberg that is now almost two kilometers away from the glacier. Grant Bigg, a principal investigator from the University of Sheffield, told BBC that the iceberg is now floating on the waters between South America's Cape Horn and Antarctica's South Shetland Islands.
If its path continues the trajectory, it might cross international shipping lanes, Bigg adds. An $80,000 emergency grant has been awarded to a team of U.K. researchers to track the iceberg's path. They will use satellites including the German TerraSAR-X.
