Digital Processing By Sea Ice Thickness Measuring
[Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management, 2005The present paper deals with digital processing aspects of real superbroadband subsurface radar signals using the inverse filtration method in the presence or absence of a priori information about the form or spectrum of sounding signal. It is proposed a new radar calibration method based on a statistical approach which comprises energy spectra ...

System and method for measuring ice thickness
The Journal of the Acoustical Society of America, 1988Sonar ice thickness measurement comprises transmitting an AM and subsequent CW sonic radiant energy signals (13,30) from a high frequency sonar transducer (11) in the water (12) toward the sonic signal reflecting ice cap (19). Reflection (30ʹ) of the CW signal (30) from the water-ice interface (18) and reflection (15ʹ) from the water-air interface (16)

This work explores the potential of using commercial single-beam echo sounders for accurate thickness determination of sea ice. Therefore, an own sensor system has been developed which allows to study the performance of different echo sounders monitoring sea ice under varying environmental conditions in a laboratory setup. The sensor system consists of

Method for continuous measurement of ice cover thickness
Cold Regions Science and Technology, 1995The objective of this study was to evaluate a method for continuous measurement of ice cover thickness. The measuring device consists of a water-filled bucket, floating with its brim at the water surface. A pipe is vertically mounted at the centre of the bucket and capped with an oil-filled balloon.

Airborne Ice Thickness Measurement System - Opportunities and Impacts
Arctic Technology Conference, 2016Abstract In ice frequented regions, the potential for large ice floes and extreme ice features encroaching on offshore structures can be significant. An early warning system is desired to discriminate between thin ice of no risk and thick ice with significant challenge.

High-resolution penetrating radar for ice thickness measurement
2012 14th International Conference on Ground Penetrating Radar (GPR), 2012We have developed a high-resolution penetrating radar to measure glacial ice thickness. With an operating frequency band of 100–150 MHz, this radar can provide a range resolution of less than 2 m in ice. The radar is designed to measure ice sheet thickness up to 3000 m.

Shipborne electromagnetic measurements of Antarctic sea‐ice thickness
GEOPHYSICS, 2003We present a study of Antarctic sea‐ice thickness estimates made using a shipborne Geonics EM31 electromagnetic (EM) instrument, based on both 1D and 3D models. Apparent conductivities measured in the vertical coplanar (VCP) geometry are shown to be the measured quantity most sensitive to changes in the height of the instrument above seawater.

Ice Thickness Distribution — Measurement and Theory
1986In considering the historical literature relevant to the subject of ice thickness distribution, I was struck by the paper by Wittmann and Schule (1966) at the Lake Arrowhead symposium on the Arctic heat budget. They presented a synthesis of visual observations from aircraft showing ice concentration, lead spacings, percent coverage of several ice types,

Upward looking ice profiler sonar instruments for ice thickness and topography measurements
Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005Scientific and engineering studies in polar and marginal ice zones require detailed information on sea ice thickness and topography. Until recently, vertical ice dimension data have been largely inferred from aerial and satellite remote-sensing sensors.

Ice Thickness Measurements on the Southern Patagonia Icefield
2002The first detailed ice thickness measurements in the accumulation area of the Southern Patagonia Icefield have been obtained with a radio-echo sounding system, revealing a complex subglacial topography and internal reflection pattern.
