First results from automated motion and stream measurements from Fels and Black Rapids glaciers, Alaska, U.S.A. (abstract) / William D. Harrison, Charles F. Raymond, Matthew Sturm, Keith Echelmeyer, Neil Frank Humphrey.
Title: | First results from automated motion and stream measurements from Fels and Black Rapids glaciers, Alaska, U.S.A. (abstract) / William D. Harrison, Charles F. Raymond, Matthew Sturm, Keith Echelmeyer, Neil Frank Humphrey. |
Author(s): | Harrison, William D. Raymond, Charles F. Sturm, Matthew. Echelmeyer, Keith. Humphrey, Neil Frank. |
Date: | 1989. |
Publisher: | Cambridge: International Glaciological Society |
In: | Annals of Glaciology. (1989.), Vol. 12 (1989) |
Abstract: | Velocity is measured over 1 d intervals by automatic photography with control and finer spatial resolution provided by periodic optic surveys. Photography also used to monitor lake and pot-hole drainings and steam behaviour. Vertical component of surface strain is measured with wire strain meters at intervals of 1 h or less; average seismicity over same interval is also measured. Stream stage is monitored by sonic ranger and temperature by instrument mounted on small platform in stream. Measurements began in 1986. Preliminary results are outlined; it was found that seasonal variations in speed are different for these two glaciers. |
