13. ABSTRACT (CONT'D)
Surveys performed at several utility sites near the main station provided a general assessment of the dielec-
tric properties of the firn, and tested the radar 's ability to delineate subsurface features and potential hazards.
Migrated, spatial images of the old clean air facility, the water well under development, and the several sew-
age sumps are presented. In general, the numerous vents, cables, antennas, etc., of the area clutter the profiles
with diffractions that complicate interpretation of the data without prior knowledge of some features. The
migrated images allowed approximations to be made as to the depths of sewage sumps, the water well and
the old buried clean air facility.
