Ice thickness measurements by Raman scattering [PDF]
Optics Letters, 2014 A compact Raman LIDAR system with a spectrograph was used for express ice thickness measurements. The difference between the Raman spectra of ice and liquid water is employed to locate the ice-water interface while elastic scattering was used for air-ice surface detection.

On the errors involved in ice-thickness estimates II: errors in digital elevation models of ice thickness [PDF]
Journal of Glaciology, 2016 ABSTRACTThis paper is the second (Paper II) in a set of studies concerning the errors involved in the estimate of ice thickness and ice volume. Here we present a detailed analysis of the errors involved in the generation of ice-thickness DEMs constructed, most often, from GPR data, complemented by boundary data and sometimes, additional synthetic data ...

Estimation of the age of ice hummocks in the freezing seas
Лëд и снег, 2019 A method of estimating the ice ridge age proposed in the 1990s was analyzed and some disadvantages of this method were shown. Analysis of the ice thickness distribution in the ice ridges demonstrated that in many cases the average value of the thickness ...

Ice thickness determination with audio sound. [PDF]
Proceedings of Meetings on Acoustics, 2013 The objective of this study is to determine the thickness of Ice by analyzing the sound spectrum generated by dispersion of lamb waves propagating in ice. In winters when the lakes and rivers freeze, it is important to know the thickness of the ice layer before one intends to walk on it.

The Antarctic sea ice cover from ICESat-2 and CryoSat-2: freeboard, snow depth, and ice thickness
The Cryosphere, 2020 . We offer a view of the Antarctic sea ice cover from lidar (ICESat-2) and radar (CryoSat-2) altimetry, with retrievals of freeboard, snow depth, and ice thickness that span an 8-month winter between 1 April and 16 November 2019.

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]
, 2007 A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...
