Marine icing sensor array for measuring ice thickness
2022Marine Icing is the process of ice accumulation on ships and other offshore structures in cold regions that can create serious working conditions besides the adverse effects to the offshore operations efficiency. Monitoring of icing conditions together with a number of de-icing strategies is therefore important in decreasing the safety hazards and ...

A Portable Radar for Ice Thickness Measurements
SAE Technical Paper Series, 1994<div class="htmlview paragraph">A high-resolution and light-weight impulse radar has been developed for short range detection of subsurface objects and interfaces. This radar can be used as a hand-held instrument or it can be mounted on a vehicle.

On the Measurement of Thickness of Ice Layers on Power Transmission Lines
Sensing and Imaging: An International Journal, 2007In this paper, measurement of ice and ice/water layer thickness on power transmission lines using Goubau modes at 1, 2.54 and 10 GHz is analyzed, simulated and discussed. Ice layer thicknesses change the phase and attenuation of Goubau mode propagation over a given line length.

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)

Measuring the Change in Thickness of the Antarctic Ice Sheet
Nature Physical Science, 1972IS the Antarctic ice sheet growing or diminishing in thickness? This is an interesting question because the change in thickness reflects, in an indirect way, the change of world climate, and also because it directly affects worldwide sea level. It is difficult to obtain the answer by measuring the mass balance of the ice sheet, primarly because of the ...

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 Measurement of Snow Thickness over Sea Ice
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008Snow cover on sea ice plays an important role in the climate of the polar regions. Snow on the sea ice reduces the heat exchange between the ocean and the atmosphere by its high albedo and low thermal conductivity. The lower the albedo, the less solar energy is reflected back into the atmosphere. Data on the extent and thickness of snow cover is needed

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,
