Ice Water Melt per Year
Date: Summer 2013
How many gallons of fresh water do icebergs release per year?
Using data from NASA, "Antarctic ice shelves lost 2,921 trillion pounds (1,325 trillion kilograms) of ice per year in 2003 to 2008 through basal melt, while iceberg formation accounted for 2,400 trillion pounds (1,089 trillion kilograms) of mass loss each year." http://www.nasa.gov/topics/earth/features/earth20130613.html#.UduRbrXVCSo
At about 8.3 lbs/gallon for water, the number of gallons from iceberg formation is about 289 T gallons, from basal melt is about 352 T gallons. That is a lot of water.
