| Summary:
UNAVCO performed a survey to measure surface displacements in Beacon Valley which occur due to sub-surface ice beneath the valley floor. This survey in January 2002 was an annual repeat of the initial survey from January 1999 and will reveal surface velocities as small as 1 centimeter/year. With a four-season time series, any movement of the valley floor will be apparent. Kinematic surveys of frost polygons and other features were also performed. These data will be used in conjunction with LIDAR data collected this season to draw inferences based on regional topography. Five geodetic receiver systems, field support, data processing, and data archiving were provided. TAMDEF survey mark BEA4 on University Peak was used for the reference receiver location. During support of G-053, UNAVCO also occupied TAMDEF mark BEA0, assisting the USGS with the annual TAMDEF survey. |
