Abstract: Because of its low melting point and large crystals, ice has provided scientists with a convenient material for the study of crystal structure. On the other hand, the anisotropy of this structure and the rheological effects of the low melting point have proved to be serious obstacles to the experimental determination of ice strength. Our knowledge of the structure of broken-up ice fields in nature is largely descriptive and therefore insufficient for the prediction of ice action. The need for in situ stress observations to supplement laboratory strength data is recognized and a first generation of field instruments is now being developed.
