A subset of GLAC1-D, GLAC2-A, and GLAC3-A last glacial cycle ice sheet chronologies for North America.

This archive of North American last glacial cycle ice sheet chronologies is from various history matching iterations (GLAC1-D, GLAC2-A, GLAC3-A) of the 3D Glacial Systems Model against a large set of paleo constraints. The archive was used in the publication: Revised constraints on the final stages of the last deglaciation from high-resolution sea-level observations. Udita Mukherjee , Lael Vetter, Glenn A. Milne, Lev Tarasov, Elena Steponaitis, Niamh Cahill, Benoit S. Lecavalier, Brad E. Rosenheim, Torbjörn E. Tornqvist, Nature Geoscience, 2025 (accepted). The subset was selected either as being a previous reference chronology or for providing a maximal range of net ice mass loss during the 9ka to 7ka interval. Anyone using this dataset must cite Tarasov et al, 2012.
