This figure appears in the Indicator: Arctic Glacier Mass Balance report.

This figure shows the cumulative change in mass balance of a set of eight routinely-measured glaciers in the Arctic located at a latitude of 66°N or higher. Each glacier is represented by a different color in the graph. With data beginning in 1945, the measurements are in meters of water equivalent, which is equivalent to the mass loss of the glacier, and representative of changes in the average thickness of a glacier. Cumulative change is determined from the base year of 1970, the first year in which all eight glaciers had annual mass balance data. The map provides the location of each glacier and the Arctic circle (dotted line) for reference.
