| Research Abstract |
To understand how microbial activities on the glacier accelerate melting of the glaciers by reducing the surface albedo and estimate the intensity of such biological albedo-reducing effects, we conducted field researches on glacier albedo, microorganisms, surface structure and environmental conditions at various types of glaciers. We could clarify various regional differences in microbiological communities, albedo and environmental conditions on the glaciers that could provide important cues to understand the relationship between the microbial activity and the albedo of glaciers.
