We have examined a sample of 4000 year old Antarctic ice, collected at theKohnen Station, by time-of-flight powder neutron diffraction to test the hypothesis ofFukazawa et al. [e.g., Ann. Glaciol. 31, 247 (2000)] that such ice may be partiallyproton ordered. Great care was taken to keep our sample below the proposed orderingtemperature (237 K) at all times, but we did not observe any evidence of protonordering.
