Sea Level and Ice Sheet Reconstructions over Glacial Cycles Posters

Session ID#: 47467

Session Description:
Advancing predictions of future sea-level rise hinges on an improved understanding of ice-sheet behavior in the geologic past. Past warm periods serve as analogues for future warming but ice dynamics and local sea-level rise are strongly linked to the preceding deglaciation. Furthermore, both interglacials and glacials are natural laboratories for studying ice-sheet stability and thresholds on rates of sea-level change. We therefore invite contributions on Pliocene and Quaternary glacial cycles, including the Holocene, that focus on local sea-level proxies and reconstructions, glacial isostatic adjustment and other forms of solid Earth deformation that contribute to local sea-level change, and models and geologic constraints on past ice-sheet changes. As part of PALSEA (PALeo constraints on SEA level rise), we particularly encourage submissions that connect with related scientific communities (for example sedimentology, paleoecology, mineral physics, geodynamics, and glaciology) and provide solutions on how to reduce uncertainties in sea level and ice sheet reconstructions.
