Ice-sheet variability and behavior through the lens of geologic data and numerical modeling
Ice-sheet variability and behavior through the lens of geologic data and numerical modeling
Session ID#: 161232
Session Description:
Ice sheets are major components of the climate system and play an important role in the organization of that system through their influence on sea level, atmospheric and oceanic circulation, the biosphere, and landscape evolution. Determining the evolution of the size, shape, and volume of past ice sheets provides necessary boundary conditions for deciphering how ice sheets responded to and influenced past climate changes. Evidence of past ice-sheet size and behavior are recorded in the geologic record through the presence of terrestrial deposits and geomorphic features, geochemical tracers, and lacustrine and marine sediments. Numerical models provide insight into the potential mechanisms of past and present ice-sheet change and can provide information not always available through the geologic archive alone, including ice-volume estimates, ice-flow dynamics, and transient ice-sheet reconstructions. This session seeks contributions addressing ice-sheet constraints from both geologic data and modeling studies to recreate past conditions of the global ice sheets. Topics will include, but are not limited to, remote sensing, geochronology, ice volume and sea-level contribution, and ice streams and ice dynamics.
