Abstract

The last deglaciation occurred from approximately 20,000 to 11,700 years ago when rising atmospheric temperatures caused Earth’s main ice sheets to melt. Vast amounts of water from the vanishing Laurentide Ice Sheet flowed through the Mississippi River system into the marine environment. The mixing of fresh meltwater with saline ocean water on such a mass scale triggered abrupt changes in regional climate, ocean…
