Definition: The reduction of glacier thickness, in excess of that due to ablation, that results when the flux divergence is positive, that is, when more mass flows out of the thinning region than flows in. See downwasting. Dynamic thinning, when not compensated by thickening in a downstream part of the glacier, implies an enhanced calving flux at the glacier terminus, or an advance of the terminus, or both. See also calving velocity.  IHPGlacierMassBalance
