DESCRIPTION: Melt layer stratigraphy for 4 Greenland Arctic Circle Traverse (ACT) ice cores collected along the southern portion of the Greenland ice sheet. Data are total thickness of melt layers in cm found within each year's stratigraphy, as measured on a light table following horizontal sectioning of the cores.
