A Field Investigation of Water and Salt Movement in Permafrost and the Active Layer

Evidence from subsea permafrost, permafrost in coastal regions of the Arctic and Antarctic, and in the cold and sometimes arid regions of China, the Soviet Union, Antarctica, and North America, indicates that saline permafrost is very widespread - perhaps more common than non-saline permafrost This...

Description
Summary:Evidence from subsea permafrost, permafrost in coastal regions of the Arctic and Antarctic, and in the cold and sometimes arid regions of China, the Soviet Union, Antarctica, and North America, indicates that saline permafrost is very widespread - perhaps more common than non-saline permafrost This salty permafrost is found near the surface at depths of geotechnical interest, within, and under continuous and discontinuous permafrost. These salts can produce significant changes in permafrost properties and processes and it is possible for these salts to become mobile under potential energy gradients. It is concluded that saline permafrost will become increasingly important in the rational assessment of scientific, engineering, environmental, and agricultural problems of the future.
