On page 2815, column 2, lines 8 to 59, we insinuate that our results seem to be in conflict with a recent in situ neutron diffraction study of high density amorphous ice (HDA) reported by Klotz et al.1,2 They found that HDA studied in situ at 0.7 GPa and 100 K has a remarkable similarity of the OO-radial density function, up to distances of 10 Å, to the ambient pressure structure of very high density amorphous ice (VHDA) measured by Finney et al.³ We assumed that Klotz et al. were therefore claiming to convert HDA to VHDA at 0.7 GPa and 100 K. However, Klotz et al. have pointed out to us that this is not the case. Instead they were able to recover HDA, which implies that HDA’s compression/decompression cycle at 100 K from 1 bar to 0.7 GPa and back to 1 bar is fully elastic and VHDA is not formed. This is in agreement with our own piston displacement vs pressure curves, and removes the basis for our discussion of a possible conflict between their results and ours.
