  Working with a two-stage ice sheet model, we explore how statistical data
assimilation methods can be used to improve predictions of glacier melt and
relatedly, sea level rise. We find that the EnKF improves model runs
initialized using incorrect initial conditions or parameters, providing us with
better models of future glacier melt. We explore the necessary number of
observations needed to produce an accurate model run. Further, we determine
that the deviations from the truth in output that stem from having few data
points in the pre-satellite era can be corrected with modern observation data.
Finally, using data derived from our improved model we calculate sea level rise
and model storm surges to understand the affect caused by sea level rise.
