Publikováno v: Journal of Glaciology. 60:440-446

This paper provides an introduction to adjoint methods, which are used to find the gradient of an objective function, as required by optimization algorithms. Examples are included, culminating in a data-assimilation problem from glaciology.

Ten ice-sheet models are used to study sensitivity of the Greenland and Antarctic ice sheets to prescribed changes of surface mass balance, sub-ice-shelf melting and basal sliding. Results exhibit a large range in projected contributions to sea-level
