This project is a Senior Essay in Geology & Geophysics.  It involves an analysis of ~200 samples collected in Antarctica in 2013. 

The program seeks to:

(1)    Understand how and why the deposition rates of Tritium in Antarctic surface snow vary with latitude.

(2)    Explain the variability of water stable isotope ratios with depth and latitude along two coast-to-pole transects.

The remote sensing lab is needed for one component of the program. I need updated elevation data on each site at which we conducted sampling, since it was inadequately recorded during the expedition.  The elevation data are needed because elevation is a key determinant of isotopic composition of precipitation
