The proposed mean ice compressive strength estimate is higher than those derived by minimizing the cumulative error between simulated and observed buoy drift trajectories. We note that the uncertainties in the estimates derived from models are large (with an unbiased estimate of standard deviation of 8.75 KN m −2 ). The estimates of yield strength in isotropic compression presented herin are in good agreement with a previous estimate made during the Arctic Ice Dynamic Joint EXperiment, and with in-situ ice compressive stress measurements made in the Beaufort Sea. 3
