| Zusammenfassung |
| The potential contribution of glaciers and ice caps to sea level rise is
usually calculated by comparing the estimated total ice volume with the
surface area of the ocean. Part of this total ice volume, however, does not
contribute to sea level rise because it is below the surface of the ocean
or below the levels of future lakes on land. The present communication
points to this so far overlooked phenomenon and provides a first
order-of-magnitude estimate. It is shown that the effect is small (most
likely about 1 to 6 cm sea level equivalent) but systematic, could
primarily affect earlier stages of global glacier vanishing, and should
therefore be adequately considered. Now-available techniques of
slope-related high-resolution glacier bed modelling have the potential to
provide more detailed assessments in the future. |
