Subglacial quarrying, thought to be dependent on basal sliding speed, effective pressure, and other factors contributing to normal load concentrations from ice on bedrock, is a significant contributor to subglacial erosion and promotes basal bedrock roughness, which limits how quickly glaciers can slide into the net mass loss zone. The data we provide here are a result of numerous load tests generating mixed-mode stress intensity factor concentrations on crack tips in bedrock steps typical of subglacial or deglaciated landscapes. In the corresponding paper, we explain the significance of each geometric variable and the implications for the favorability of existing cracks to grow. We combine our stress intensity factors into a growth rate index normalized to the ice load so others may consider a variety of hypothesized conditions. In the supplement we expand on the current state of potential subglacial normal and shear loads, provide additional results for the variables covered in the paper, and show the outcomes of various sensitivity tests.
