Definition: The set of points separating the floating part of a glacier from the grounded part. See flotation. Usually the floating part is downstream and the grounded part is upstream. However, the 'shorelines' of subglacial lakes are grounding lines.  IHPGlacierMassBalance 

The junction between a glacier or ice sheet and ice shelf; the place where ice starts to float. This junction normally occurs over a finite zone, rather than at a line.  IPCC2013
