Mass Balance, Meteorological, Ice Motion, Surface
Altitude, and Runoff Data at Gulkana Glacier, Alaska, 1992 Balance Year
by Rod S. March and Dennis C. Trabant
U.S. GEOLOGICAL SURVEY
Water-Resources Investigations Report 95-4277
ABSTRACT
The 1992 measured winter snow, maximum winter snow, net, and annual balances in the
Gulkana Glacier basin were evaluated on the basis of meteorological, hydrological, and
glaciological data measured in the basin and are reported herein. Averaged over the
glacier, the measured winter snow balance was 0.97 meters on March 26, 1992; the maximum
winter snow balance was 1.05 meters on May 19, 1992; the net balance (from September 8,
1991 to August 17, 1992) was -0.29 meters; and the annual balance (October 1, 1991 to
September 30, 1992) was -0.38 meters. Ice surface, motion, and altitude changes measured
at three index sites document seasonal changes in ice speed and glacier thickness. Annual
stream runoff was 1.24 meters averaged over the basin.
