Adding embedded simulation to the parallel ice sheet model

Understanding the impact of global climate change on the world's ecosystem is critical to society at large and represents a significant challenge to researchers in the climate community. One important piece of the climate puzzle is how the dynamics of large-scale ice sheets, such as those covering Greenland and Antarctica, will respond to a warming climate. Relatively recently, glaciologists have identified ice streams , which are corridors of ice that are flowing at a much higher rate than the surrounding ice, as being crucial to the overall dynamics and stability of the entire ice sheet. However, ice stream dynamics are not yet well understood, and it is thus important to develop simulation models through which we can develop deeper insight into their behavior and their interactions with the large-scale ice sheet. In this extended abstract, we present our novel approach to developing such simulation models.
