Thwaites Glacier is located on the Western border of the Antarctic continent. A large area of the West Antarctic Ice Sheet flows to the ocean via Thwaites Glacier, which extends over 192,000 sq kms (74,000 sq miles), an area the size of Florida or the island of Britain. It is also one of the most rapidly changing glaciers in Antarctica. Thwaites Glacier straddles some of the deepest bedrock in Antarctica, increasing its sensitivity to change. Over the past 30 years the amount of ice flowing from this 120 km-wide region has doubled. Ice moving off the land into the ocean will affect global sea level, but by how much and how fast?

The US National Science Foundation (NSF) and UK Natural Environment Research Council (NERC) have combined forces supporting eight separate research and modeling projects with over 60 scientists and students to investigate this rapidly changing area through the International Thwaites Glacier Collaboration (ITGC).
