Comment:
Waelbroeck et al, 1995 have applied the orbital tuning approach to the deuterium record to derive a timescale which is consistent with the SPECMAP marine timescale. IMORTANT: because of filtering errors due to the finite length of the record, the upper and bottom 20 to 35 ky of the orbitally tuned chronology can not be trusted. In the present file, the upper 3 5ky of the orbitally tuned chronology have been replaced by the EGT timescale.
