Freezing Samples in Shelby Tubes for Sampling Shipping
I recently saw a standard operating procedure for shipping Shelby Tubes to the laboratory in which the sample was packed in dry ice to freeze it quickly. The rationale for this was to make the sample less subject to disturbance during all the bouncing and vibrations involved in long distance shipment. The assumption is that the freezing does not alter the physical properties of the sample, i.e., it is still an "undisturbed" sample. Has anyone had any experience with this approach? I am concerned that freezing can produce wholesale disturbance of the soil structure and key physical properties.
