What’s more, the Larsen Ice Shelf was only just beginning to reveal its secrets. In July 2017 researchers reported that further change was afoot in Larsen C, currently one of the biggest ice shelves in Antarctica. That month, a massive 2,240 square mile section of ice separated from the main shelf and began to drift away.
The resulting iceberg was apparently so large that it reduced the size of the Larsen C ice shelf by around 12 percent. According to scientists, its dramatic formation was the result of a natural process, rather than a sign of climate change. And as it carried a trillion tons of ice out into the Weddell Sea, it left something fascinating behind.
