Measurement of sea ice thickness with airborne electromagnetic system

54th EAEG Meeting, 1992
For winter navigation in Finland it is economically important to know the ice conditions on the sea. First tests have been done with the fixed wing airborne electromagnetic system of Geological Survey of Finland to check its capacity to measure ice thickness quickly and economically.

Ice thickness measurements by Raman&Rayleigh scattering technique

2016 International Conference Laser Optics (LO), 2016
An efficient technique for ice thickness measurements by Raman&Rayleigh scattering is suggested. The elastic scattering is used for air-to-sample borders indication but fails to detect floating ice border. The Raman spectroscopy is used to detect interfaces between transparent materials such as ice-water interface.

Airborne Measurement of Snow Thickness over Sea Ice

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Snow 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

Measurement of Sea Ice Thickness With Airborne Electromagnetic Equipment

Offshore Technology Conference, 1989
ABSTRACT The topography along the ice water interface can be recovered from airborne electromagnetic data With an Iterative inversion scheme. This method is based on a new fast algorithm for solving the forward problem, which can be used to evaluate electromagnetic scattering by an irregular but highly conductive ...

Using of Radiolocation Measuring Devices of Freshmater Ice Thickness

[Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management, 2005
The paper presents information about few devices, elaborated in Riga Institute of Civil Aviation Engineers for freshwater ice remote measurment. Devices may be installed on aircraft or automobile and make it possible to carry out reconnaissance in rivers, lakes and reservoirs, to choose ice landing zone for primary landing. Devices also can be used for

Ice Thickness Precise Measurement System Based on Computer Vision

2009 WRI Global Congress on Intelligent Systems, 2009
The real-time measurement system is composed of two digital cameras, a computer, a coding scale control board and an illumination lamp-house. Digital cameras are set above the glass window of the wind tunnel and focused to the sensor part. Images of the growing ice will be transferred into the control computer continuously and be processed by the ...
