Using remotely sense data, OLI, ETM or TM of landsat or even usning sentinel data, is it technically possible to estimate ice thickness in a glacial body?
no we cannot measure with landsat l data for ice sheet thickness.
sentinel altimeter is possible to measure thickness only below 10 inches

Well,
A ruler is used to estimate the thickness of the snow in several places to give the average thickness of a fish in an area, and permanently fixed lists with a clear gradient are used in areas where snow is falling permanently, indicating snow thickness.
For this purpose special devices are used with radioactive material for gamma rays, eg Cobalt-60. This device works on the principle of changing the pattern of receiving gamma rays caused by radioactive materials in the ground. This device is connected to central monitoring stations by means of a special transmitter, which directly transmits the amount of snowfall equivalent to that of water. The weight of the ice can be measured directly by the plates connected to a scale that directly measures the weight of the accumulated snow, and then we convert this weight to the equivalent of water according to known equations. Satellites, which are based on special techniques, are used to determine the area covered by snow within the water discharge ponds. Private aircraft may also be used to take aerial photographs for the same purpose.
