Consider the isostatic rebound after removal of an ice load. Given the response time, t, of 4 ka (as we found for the Fennoscandian ice sheet), a time since unloading of 9 ka, an asymptotic maximum rebound w_o of 180 m, and a response function that looks like:

where t is the time of removal of the load, answer the following questions:

(i) How much rebound has yet to occur in the  future? What is the present rate of rebound?

(ii) Discuss what the 180m implies in terms of  the ice load, and in terms of the duration of the loading.
