Glaciological Catalogue of Georgia

since 1960 years the number and area of glaciers in Georgia has not been identified, as well as their exposition, morphological types,  elevation above sea level and other glaciological parameters, therefore,  the aim of the project is to determine the number and area of glaciers and to determine the dynamic of glaciations in XX century and in the beginning of XXI century, to determine and reveal the correlation relations, on the one hand, among the glaciers’ morphometric features (area, tongue length, average height, snow line height) and on the other hand, among the mean annual temperatures and the sums of positive temperatures, which will help us to determine the interrelation between the glaciers’ fluctuation dynamics and global warming.
The final result of the research will be the creation of Georgia Glaciers (glacilogical) catalogue, which will be  billingual – Georgain-English   and it will include the glacier maps of 1 : 50 000 scales according to the following river basins – Enguri, Rioni,  Bzipi, Kodori, Tergi, Liakhvi, Asa, Arghuni, Pirikita Alazani and Aragvi. The Catalogue will be of high scientific level and it will includ the newest information. It will be  illustrated by maps, digital three-dimensional models of glaciers and photo materials. Monograph on Glaciers of Georgia will be prepared and published at the last stage of the project.

Development of Glaciological Researches of Georgia by Using Remote Sensing Method

For the conducting research of glaciers by state of the art method it is important to command cutting-end methods and implement them in our country.
In glaciological research large experience was gained over 20-th century, but remote sensing method heve never been used before. This method  is ideal for annual monitoring of glaciers, determing thier quantity, exposition, height above mean sea level, morphological types and current climate change development. All above mentioned works will be implemented in the framework of this project, which makes uniqueness of this work.
The most importance of using remote sensing method in research of glaciers makes the fact that field expeditions in temporarily occupied Tskhinvali and Abkhazia regions is not possible for us yet. To determine above mentioned parameters and all necessary information for the glaciers located on these territories will be implemented by using this method.  For the minimization of errors will be compared glaciers of these territories to other analogue morphological type glaciers of Caucasus and by the extrapolation will be defined information gained during the research conducted before.
Information gained by above mentioned mehod can be used in future as a model for detemine the quantity, morphological types, dynamics of glaciers of Georgia, evolution of glaciation and other glaciological information.

The Glacio-Geomorphological Study of the Glaciers of Georgia on the background of Modern Climate Change

Digital model of glacial basins will be created in geographical informational system (GIS) in the framework of the project. Here is mentioned as creation of different scale relief models as plotting of all significant geographical, geomorphological and glaciological objects and phenomena by GPS and their mapping on digital model. According to this relief model scales of glacier retreat from the Late Pleistocene until now and areas of old moraines extension will be determined. The restoration of last stadial glaciation scale, plotting those period moraines and mapping of their extension areas on digital model will be implemented. The glaciers shrinking indices as their length as well as volume will be specified. In the framework of the project from 1950 until now, existed and available satellite and aerial images interpretation will be made. Glaciation dynamics of XX-th century and the beginning of XXI century will be determined. Correlation link between glacier morphometric features (volume, length of tongue, mean height, firn line height), also between average annual temperatures and positive temperature sums on the firn line height will be defined. According to them interaction between dynamics of glaciers fluctuation and modern change of climate will be determined.
For some large glaciers animation map in GIS system will be created. The territory for glacial park of Georgia will be selected and scientific proof for tourist purposes will be made. Workshop with foreign colleagues will take place and they will be acquainted with current study. Gained data will be exchanged with different glaciological profile scientific centers. Paper will be published in high-ranking foreign scientific journal.
As above was mentioned digital models for  glacier basins relief and  data base of glaciers from 1810 till now will be created in GIS program. Significant geographical and geomorphological objects data base will be compiled, which can be basis for the creation of different river basins data base of Georgia. The obtained results will be published on the  web-page of TSU Institute of geography and interested parties will be able to get information and maps related to glaciers.

The Study of the Glaciers of the Tergi River Basin on the Background of Modern Climate Change, Paleo-Glaciological and Paleo-Geomorphological Reconstructions of Late Pleistocene and Holocene

Digital model of the Tergi River Basin will be created in the Geo-Information Systems. It is supposed both, to create its relief’s models of different scales and GPS-survey of the most important geographical, geomorphological and glaciological object or phenomena with their affixation on the digital model. Also, with the help of the obtained model of the relief the retreating scales of the glaciers and the distribution areal of the old moraines will be identified since Late Pleistocene until the present. Scales of the latest stage glaciations will be reconstructed, the moraines of the same age will be surveyed and their distribution areal will be affixed on the digital model. Respectively, the glacier’s retreating index of the length and area will be specified from this period. Within the Project the of current and available aero-space and aerial photo images of the period from 1950s to present days will be decoded and thus the glaciations dynamics of the last 70 years will be specified in more details.
As I have mentioned, the digital model of the relief of the Tergi River Basin will be created, as well as the glaciers database (model) of different years since 1810 (the last stage glaciations) – until the present in the Geo-Information Systems’ (GIS) programs, and the database of important geographical or geomorphological objects, that can be become the basis for the creation of geodatabase of the different river basins of Georgia. The obtained results will be published in the Internet, in the website of the TSU Vakhushti Bagrationi Institute of Geography and interested persons will be able to download any information regarding the glaciers and other geographical elements, as well as the maps and data base, in the relevant formats.
During the Project implementation we will get in contact with our international colleagues and hold the Workshops (as far as possible), thus they will be interested in such researches in Georgia; the obtained field data will be exchanged with the world’s different Scientific Centers of glaciological profile.
My experience gained as a result of participation in the expeditions conducted in the high mountainous zones (in the individual glaciers) in the last period (2004-2012), as well as knowledge of modern technologies of field and office researches, gives me the opportunity for Project’s real implementation.

Mass balance monitoring of Zopkhito Glacier

Research of  glaciers is very significant in the world. For the perfect research it is important  to carry  many year  complex observations. Glaciers are unique objects of geographical sphere, where occurs gathering of solid atmospheric precipitation and their transformation into ice.  They move downwards with power of gravity. Glaciers are largest reservoirs of water  in the whole earth and are the important resources for the country. Observation of glaciers was conducted actively since 1960 in Georgia. Recent year observations almost stopped. Vakhushti Bagrationi Institute of Geography gained international grant in 2006-2008. Hence there was conducted 2 year complex observation on Zopkhito glacier. We think that work on this glacier must go on, which will give us opportunity to made Zopkhito as model glacier for complex glaciological observations in Southern Caucasus.   For the high scientific observations it is necessary to conduct permanent observation on the mass balance, which itself is balance between incoming solid precipitation in winter period (accumulation) and  output of mass (ablation) in summer. Mass balance spell important information on climate change tendencies in regional scale as estimation of discharge.
The same work occurs in every model glacier of mountainous region. We think analogue model glacier is Zopkhito, because the same kind of observation was done through INTAS project   “Modeling Climate Change, Glacier Dynamics, and Water Availability in the Caucasus” which was implemented in 2006-2008.

Modeling Climate Change, Glacier Dynamics, and Water Availability in the Caucasus

Collaborators Institute of Geography participated in INTAS project  ,,Modeling Climate Change, Glacier Dynamics, and Water Availability in the Caucasus” in 2006-2008. In this project worked  Maria Shahgedanova (the University of Reading), Vladimer  Popovnin (Moscow State University), Otfried Baume (Ludwig Maximilians University of Munich) and other scientist;  According to the project workshops were organized  in cities reading, Moscow and Munich. We have made reports about field work researches conducted in Zopkhito. We were provided with project automatic weather station and thermo drill (temporally using). Joint field expedition was arranged with Russian colleagues for snow planning on the glacier Zopkhito In spring 2008  (5-28 May). Observations was carried out together with German scientists on the ablation From 20-th June to 10-th July. In September was carried out photo theodolite survey and 1:5000 scale map of basin was created. our representatives  were sent in North Caucasus on the glacier Djankuat in August.
Our colleagues  are very interested in continuing of field observations on the glacier Zpkhito and go on with stationary observation like Djankuat where observations have been made almost 40 years. They are ready to make joint research in Georgia. There are some glaciers in the world with stationary observation and none of them in the South Caucasus. They promised to help us for include Zopkhito glacier in world glacier monitoring network if we maintain observations there. Georgian scientists have a experience in conducting  researches in modern way.
