Outline of Final Research Achievements

We genetically analyzed microorganisms collected from the glaciers in various part of the world and found regional difference in species composition of bacteria and cyanobacteria in cryoconites, biogenic dark granules on the glacier that accelerate glacier melting. We could also identify symbiotic bacteria of glacier animals. We developed mathematical model simulating changes in cryoconite holes, melt holes on the glacier formed by cryoconite, to establish the mass valance model of the glacier including biological albedo reducing process.
