520 3# ‡aResponse time of temperate glaciers is estimated by continuity argument, as follows. Difference in steady-state ice volume of glacier before and after mass-balance perturbation must be accumulated or ablated before glacier can reach new steady state. This leads to time scale which is termed volume time scale of glacier and it is argued that response time of glacier can be expected to equal this. Volume time scale can be derived by simple deduction and may be expressed by formula Tv=H/(-bt) where H is thickness scale of glacier and bt is scale of ablation along terminus of glacier. This estimate of response time of glacier is of order of decades for small maritime glaciers, which is in reasonable agreement with experience. It is much shorter than theoretical long response time of order of several 100 or 1000 years which has been derived in past from kinematic wave theory.
