This award represents one element of the second Greenland Ice                   Sheet Project (GISPII).  This investigation will focus on the                   stratigraphy, relaxation characteristics and crystalline structure              of ice cores from the GISP II deep drilling at the Summit site,                 Greenland.  Studies will include: 1) delineation of annual                      layering, 2) precision density measurements to monitor the                      relaxation characteristics of ice cores as they age, 3)                         determination of the principal mechanisms by which cores relax,                 4) crystal size measurements as a function of the depth and age of              the ice, 5) c-axis fabrics measurements, and 6) analysis of debris              in basal ice cores.  Relaxation of ice results in significant                   changes in their mechanical condition that must be considered in                relation to the preparation and analysis of core samples for                    entrapped gas and chemical studies; c-axis fabrics constitute the               primary source of information for interpreting the strain history               of the ice column that vertically drilled cores represent.                      Accordingly, very careful documentation of these key properties of              summit site ice cores is essential if we are to accurately assess               the depth - age relationship of deep cores and have confidence in               paleoclimate reconstructions based on geochemical and entrapped                 gas analysis of these cores.
