INFRARED MAPPING OF THERMAL ANOMALIES IN GLACIERS
Canadian Journal of Earth Sciences, 1966All-season aerial reconnaissance of the Arctic has been advanced with the development of airborne, infrared scanners. The utility of such equipment for detecting and studying the progression of thermal anomalies of glaciological interest is discussed with reference to specific examples of imagery obtained during three seasons on Project "Bold Survey ...

SOME FUNDAMENTAL CONSIDERATIONS ON GLACIER MAPPING
Canadian Journal of Earth Sciences, 1966Five glacier maps at scales of 1:5 000 and 1:10 000 were produced by the Photogrammetric Research Section of the National Research Council and the Axel Heiberg Island Expedition of McGill University for use in glaciological research in the Canadian Arctic. After general comments on the need for and scope of glacier mapping, the authors discuss in some

IEEE Transactions on Geoscience and Remote Sensing, 2011
We performed airborne experiments using 150- and 450-MHz radars to measure ice thickness on the Greenland ice sheet. Our objectives were to investigate to what degree surface clutter obscures the basal echo when airborne measurements are made at different elevations and at different frequencies.

Lateral Mapping of Glacier Flow Speed with a Scanning Radar
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018A polarimetric coherent Ku-band radar system with electrically steered antennas has been tested for lateral velocity measurements of the Kronebreen glacier at Ny-Alesund, Svalbard. The paper presents the radar and interferometric velocity measurements of the glacier.

Glacier Thickness Change Mapping Using InSAR Methodology
IEEE Geoscience and Remote Sensing Letters, 2014This letter presents a novel method for high-precision estimation of mountain glacier thickness change from the conventional interferometric synthetic aperture radar (InSAR) interferograms and multiaperture InSAR measurements. The method exploits the two components of displacement along the line of sight of radar beam and along track for deriving the ...

Mapping glacier ice thickness in Chile
Knowledge of ice thickness is essential for understanding past and predicting future changes of glaciers systems in response to climatic changes. Various methods exist on how to best estimate ice thickness from surface information in data sparse regions.Jorge Berkhoff +7 more
