Researchers in the United States have uncovered what they believe is evidence to suggest that once-massive icebergs floated from northern Canada to southern Florida.
Using high-resolution sea floor mapping, researchers at the Woods Hole Oceanographic Institution and the United States Geological Survey discovered about 700 iceberg scours -- a term referring to “plow marks” on the ocean floor from icebergs -- that run from North Carolina to the Florida Keys.
Given the high temperatures in the ocean water near the southern states and the natural flow of the Gulf Stream in the opposite direction of the icebergs’ travel, the researchers believe the only way the iceberg could make it that far before melting is “massive, but short-lived” glacial meltwater discharge from Hudson Bay.
