We analyse ICESat-1 laser altimetry observations, corrected by a firn compaction model, to obtain spatial patterns of thickness change.
We infer ice thickness change from the floatation condition and thus the bedrock elevation at the identified grounding line position.
Nuth, C. & Kääb, A. Co-registration and bias corrections of satellite elevation data sets for quantifying glacier thickness change.
Based on the periods between the acquisitions, ice thickness change rates and their respective errors are reported from buoyancy calculations.
The total ice thickness change, based on the cross profile comparison, is almost identical to the magnitude derived from the total lateral grounding line displacement.
As an example, cumulative specific mass changes were most negative in the Southern Andes with an average regional glacier thickness change of approximately −40 m w.e.
On more closely packed planes, ND, structure and thickness change simultaneously.
If the thickness change is not possible, increasing the connection plate length may be a good alternative.
Therefore, the identification of the wall thickness change by detecting the feature interaction is required in the moldability assessment.
This indicates an earlier onset of the thinning, although no measurements are available for the fjord bottom at the location of the 1994 grounding line, which inhibits the quantification of ice thickness change in this early period.
Also the along flow velocity gradients did not change significantly over this period, indicating that the calculated ice thickness change is not related to dynamic thinning of the glacier.
