I  was a postdoctoral research fellow for the Paleoclimates from Arctic Lakes and Estuaries (PALE) project . PALE scientists are involved with reconstructing the climate in the north Atlantic and Beringia (Alaska and Siberia) regions during the past 20,000 years. I coordinated the modeling efforts for the PALE project.

PALE research included the following:

1. Simulation of the climate at 10,000 years ago (10 ka) with GENESIS 2.0 Model (Pollard and Thompson, 1997) coupled with the EVE (Equilibrium Vegetation Ecology) model. The start of the Holocene at 10 ka marks the summer insolation maximum since the height of the last glacial period. This time also marks the end of the influence of the ice sheets on the climate of Beringia. The land bridge connecting Siberia with Alaska had also just been inundated.

2. The climatic effects of an ice sheet in East Siberia during the Last Glacial Maximum (LGM) at 21,000 years ago with the GENESIS 2.0 model. Most previous simulations of the LGM include an ice sheet in East Siberia, but there is little evidence that such an ice sheet ever existed.

3. Regional model simulation of the north Atlantic using ARCSYM (Lynch et al. 1995), a version of RegCM2. I completed an experiment using  modern observational and reanalysis datasets to drive the mesoscale model.  Future experiments were to use  NCAR Climate System Model (CSM) modern simulations for present and 6000 years ago as a driver for ARCSyM. Additional CSM experiments are currently being run by the Paleoclimate Working Group .
