The stunning sight of emerald green-colored icebergs in Antarctica has been documented for more than a century — in literature and beyond. "Subsequent measurements of low DOC values in green icebergs, together with the recent finding of large concentrations of iron in marine ice from the Amery Ice Shelf, suggest that the color of green icebergs is caused more by iron‐oxide minerals than by DOC." Warren, a professor at the University of Washington and glaciologist who has been studying green icebergs for decades, said researchers used to believe seawater freezing onto the base of icebergs — combined with the icebergs' already blueish shade — contributed to the green color. If our theory proves correct, green icebergs could be more important than scientists thought."
