The Penetration Of Light Through Snow And Ice Cover, W. C. Croxton, W. B. Thurman, Theodore Shiffer Jan 1937

The Penetration Of Light Through Snow And Ice Cover, W. C. Croxton, W. B. Thurman, Theodore Shiffer

Journal of the Minnesota Academy of Science

During several months of each year, soil and bodies of water in high latitudes are separated from the enveloping atmosphere by a layer of snow and ice of varying thickness. The effects of this insulating layer are not well understood, having received relatively a rather surprisingly small amount of attention by ecologists. It is known that snow cover influences the heat exchange between the surface of the earth and the air. Ice is thought to interfere with gas exchange between water and air and with aeration by wave action to the extent that epidemic losses of fish life occur through …
