Iceland ice sheet paleo-constraint database

We present an IcelandICE database of geological constraints that capture the spatial and temporal evolution of the IIS throughout the last glacial cycle. Our database is a compilation and refinement of published geochronological data (Norddahl and Pétursson, 2005; Licciardi et al., 2007; Benediktsson et al., 2022b, 2023a, b, c). The geochronological constraints are classified into two categories. One category is observations of past ice extent (paleoEXT), which consists of marine radiocarbon ages. The other is past ice thickness (paleoH), which consists of terrestrial cosmogenic and radiocarbon ages.
