The objective of this study is to develop new glacial lake inventory to understand existing condition using the optical imageries of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, nicknamed "Daichi"). Glacial lakes can be caused outburst flood when natural dams terminated by moraines are broken, and it represents serious hazard damage in downstream regions. Problems of glacial lake outburst floods (GLOFs) are that anyone does not know when it will occur and how much damage causes by it. To contribute these problems, new glacial lake inventory is currently developing in the Bhutan Himalayan using ALOS imageries. This paper describes procedure of the inventory development including image processing that introduces pan-sharpened and ortho-rectified images by PRISM and AVNIR-2, glacial lakes extraction, and its validation. © 2011 IEEE.

To form a clearer understanding of the spatio-temporal variability of the glaciological environment in Dronning Maud Land (DML), East Antarctica, glaciological investigations were carried out along the 2800-km-long Japanese-Swedish IPY 2007/2008 traverse. The traverse route covers ice sheet ridges and two deep ice coring sites at Dome Fuji and EPICA DML. The surface mass balance (SMB) distribution was derived based on analysis of isochrones within snow pit samples, fim core samples and subsurface radar signals. The SMB averaged over various time scales in the Holocene was determined. This was then compared with various data such as surface elevation, surface slope, prevailing windfield, ice thickness, polarization ratio of satellite-based microwave emissivity and normal backscattered strength of VHF radio waves from within the ice. We find that the large-scale distribution of the SMB depends on the surface elevation, continentality and interactions between ice sheet ridges and the prevailing counterclockwise windfield in DML. A different SMB is found for the windward and leeward sides of the ridges. Local-scale variability in the SMB is essentially governed by bedrock topography which determines the local surface topography and the probability of snow deposition. In the eastern part of DML, the accumulation rate in the second half of the 20th century is found to be higher by ~15% compared to averages over longer periods of 722 a or 7.9 ka before AD 2008. A similar trend has been reported for many inland plateau sites in East Antarctica. © 2011, The Japanese Society of Snow and Ice / Japan Society for Snow Engineering. All rights reserved.
