Ice ablation measured by stakes and terrestrial photogrammetry : a comparison on the lower part of the White Glacier, Axel Heiberg Island, Canadian Arctic Archipelago / K.C. Arnold. : En36-511/19E-PDF

"On the lower part of the ablation area of the White Glacier standard terrestrial photogrammetric techniques were used to measure the height difference of the glacier surface (21 June 1969 to 5 August 1969, and 5 August 1969 to 4 August 1970) at 689 points spaced on a 50 m grid, covering an area of 1.7 km2. Twenty-two ablation stakes served as control. Photogrammetry is not necessarily considered a method of replacing stakes for measuring specific ice ablation, because a glacier's specific vertical velocity components, necessary for deducing ablation from height changes, can only be measured by stakes anchored in the ice"--Abstract.
