Comparison of a Light Microscopy Image and Low Temperature Scanning Electron Microscope Image of the same Ice Crystal


The following images were obtained using a Low Temperature Scanning Electron Microscope (LT-SEM) that is located in the Beltsville Agricultural Research Center in the Electron Microscopy Unit, Bld. 465, Beltsville Maryland 20705. Information gained from studying the structure of snow is vital to several areas of science as well as to activities that affect our daily lives and is only one of several agricultural research projects that are currently being pursued in this research unit.
