 has published more than 300 articles. His monograph. The 

 Subartic, sums up the material on the tundra belt, and was the 

 first geography treatise to be awarded a Stalin Prize. In his 

 articles from 1928-1930, he introduced a new direction in ge- 

 ography, subsequently named "dynamic geography," in which 

 great stress is paid to natural processes. He has attempted to 

 convert geography from a descriptive science to one which es- 

 tablishes general laws of physico-geographical processes, 

 based on studies of the paleography of the Quaternary Period, 

 on discoveries of fresh-water diatomites, and on the evolution 

 of phy si CO -geographic processes on the earth's surface since 

 the Devonian Period.
