Description

Abstract Text:
The PIs propose to develop a statistical model for inferring past mean global sea level (GSL) and ice sheet volumes from geological indicators of changes in local sea levels. This model will employ a Bayesian statistical framework to combine geological observations and their uncertainties with a geophysical model of the spatial and temporal sea level patterns associated with different meltwater sources. The proposed work focuses on three specific applications:
(1) evaluating the contribution of different ice sheets to high GSL during the Last Interglacial stage, ~130-115 thousand years ago;
(2) assessing ice sheet history from the Last Glacial Maximum (LGM) to the present, in particular estimating the net ice volume change across this time interval and assessing the relative contributions of the Laurentide and Antarctic ice sheets to meltwater pulse 1a at ~14.3 thousand years ago; and
(3) over a broader sweep of the Quaternary and Pliocene, investigating the relationship between Northern and Southern hemisphere ice volumes and paleoclimate proxies.

The geological record of past ice sheet responses to climate change can serve as a key data source for testing forward physical models of ice sheet dynamics under different climate scenarios. The model developed in this project will be an effort to synthesize such a data set, evaluate its associated uncertainties, and employ it to strengthen understanding of the relationship between key climate parameters (such as polar and circum-polar temperatures) and ice sheet stability.

It is important to recognize, and consider in any interpretation of Federal RePORTER data, that the publication and patent information cannot be associated with any particular year of a research project. The lag between research being conducted and the availability of its results in a publication or patent award varies substantially. For that reason, it's difficult, if not impossible, to associate a publication or patent with any specific year of the project. Likewise, it is not possible to associate a publication or patent with any particular supplement to a research project or a particular subproject of a multi-project grant.
