Modern Methods of in Situ Studying for Mountain Glaciers on Eastern Siberia’s South
A special method of collecting and processing of spatial and climatic data in remote areas of southern East Siberia, with modern glaciation was developed. It is based on field research, geodetic survey, laser scanning, residual strength measurement, analysis of satellite images, the use of GIS technology, nonvolatile temperature sensors (thermochrons), and synthesis of materials in the form of a database. In this paper the attention fixed on in situ methods of study of mountain glaciers as main source of taken of facted materials. Such methods are next.
- Year-round meteorological observation near studying objects by thermo registers
- Geodetic fixes of reference points on object’s surface by portative navigation devices
- Georadar survey of ice thickness from glacier’s surface
- The measurement of residual strength of moraine deposits by sclerometer
- Laser scanning of slopes for the detection of its geomorphologic features
The using thus methods in add to remote sensing observation of earth surface allow making a complex study of modern glaciations of Near-Baikal mountain ridges: the Kodar ridge, Barguzinskii and Baikalskii ridges, East Sayan. It allow to see the grade of participating of nival-glacial formations in geomorphologic processes also.
The GIS-project it’s, probably, the best way to joint of difference data. In this project we can to concentrate data on the one cartographic basis with appropriate database for next automatic analyze that information.
