Summary: | accumulation, B (positive for melting), and the dif-ference in ice ßux between the two gates per unit area,]H /]t 5 A 2 B 1 (fGL 2 fDG)/ISA, where fGL and fDG are the ice ßux for the GL and the DG, respectively. Under steady-state conditions,]H /]t 5 0, and neglecting surface melt and accumula-tion (,0.5 m/year) compared with basal melting, B is equal to the decrease in ice ßux per unit area. If the ice shelf is thickening (thinning) and ice ßow is steady, then B would be lower (higher) than calcu-lated under steady-state conditions. 11. J. Weertman, J. Glaciol. 13, 3 (1974). 12. C. J.
