| Summary: | In this report we describe the measurements we made on saline ice at CRREL during January 1993, and we discuss some preliminary results and interpretations. In addition, we discuss directions to take regarding analysis of this year's CRREL data, and ideas for future work. We obtained extensive surface roughness and physical properties data using a variety of instruments and techniques, particularly for the ice grown indoors in the pit. We took care to take measurements in conjunction with the radar measurements taken by the University of Kansas group in the pit, so that the radar and physical properties data could be meaningfully combined. Outdoors, we also tried to take data in regions of the pond and at times that coincided with the passive and active microwave measurements being made by various groups. This report is divided as follows: we describe our surface roughness measurements for both the pit and the pond in Section 2, and salinity and structure measurements in Section 3. In Section 4 we discuss our findings , and in Section 5 we discuss future work. CRREL (Cold Regions Research and Engineering Laboratory)
