Flooded cracks in first year sea ice refreeze rapidly, their physical and mechanical properties being governed by heat flow to the ice-air interface and laterally to the surrounding ice sheet. Here we investigate the crack strength by first finding the flexural strength of the pristine ice sheet usi...
