Subtropical icebergs and freshwater forcing of climate
| |||||
This fascinating study uses a combination of high-resolution glacial numerical ocean circulation modeling and high-resolution multibeam bathymetry data to show that massive (up to 300m thick) icebergs and large volumes of meltwater were periodically transported along the east coast of North America to southern Florida during the last deglaciation (~21,000 to 6,000 years ago). These events would have been marked by the sudden appearance of enormous icebergs along the entire east coast of the United States, as far south as Miami, Florida.

The above stylized image shows the massive icebergs that an observer sitting on a beach in southern Florida would have periodically seen drifting along the coast ~18,000 years ago.
