This award supports a project to develop the techniques for separating net
accumulation into precipitation and sublimation in polar firn. The project will
use existing models for firn ventilation and models for the transfer of
chemical species to firn to create an integrated model of vapor and chemical
species transport in firn for suites of species that respond differently to
water mass loss. This forward model will predict the dependence of geochemistry
on water vapor loss. The knowledge gained from these forward models will then
be used to solve an inverse problem to predict the amount of water vapor
sublimation and redeposition based on profiles of geochemistry in firn. This
project is a necessary first step toward inferring precipitation and
evaporation in ancient environments, such as are recorded in ice cores. This
project will serve as the basis for a Ph.D. dissertation for a student under
the direction of the P.I., E.D. Waddington. Determining how to best extract
climate information from firn and ultimately ice cores is the major goal of
this project.
