A Numerical Method of Inferring the Budget History of a Glacier from its Advance and Retreat
Abstract The paper considers how to calculate the budget history of a glacier from the historical record of its advance and retreat. The linearized differential equations developed in previous papers are used to compute a series of coefficients g ( n ). The g ( n ) operate directly on a record of an...
