  <Summary>Carl S. Benson's Greenland snow accumulation study field notebooks and analyses of snow accumulation, temperature, ice sheet facies and snow densification are available on 74 microfiche or as hard copy for on-site use by appointment. The data set includes a summary of all sampling stations, summary matrix of data collected at each station; accumulation data adjusted for Fall 1954 and Fall 1955 reference horizons; average accumulation for all stations; integrated ram hardness (snow density); descriptive stratigraphy, pit profile temperature and density; and pit and core temperature, density, ram hardness and stratigraphy. Benson's notebook is available only in hard-copy, for use on-site use by appointment only.

Copies of microfiche are available. Please contact NSIDC User Services for more information or to schedule on-site use.</Summary>
