Investigating glaciers in depth.

Sources say that, global sea levels are rising constantly and one factor that is mainly contributing to this rise is the melting of the glaciers. Although the surface area of the glaciers has been well mapped, there is often no information regarding their thickness, making it impossible to calculate their volume. As a result, the effects on sea levels cannot be accurately calculated. 

Researchers have developed an approach which can be used to draw up regional ice thickness maps for glaciers.These ice thickness maps gives new insights into the dynamic ice loss of glaciers. When new snow falls, its weight compresses previous layers of snow and a new mass of ice is gradually formed. 

With the help of this ice thickness map, now we can accurately estimate the dynamic ice loss.
