U22A:
Nowhere to Hide: The Explosion of Geodesy and Its Ongoing Transformation of the Earth Sciences

Note: Abstract submissions to Union sessions are by invitation only.


Session ID#: 8588

Session Description:
Although geodesy is one of the oldest disciplines in the earth sciences, it has been reinvented over the past two decades with the advent of the global navigation satellite system (GNSS) and new techniques for rapid surface mapping (Lidar, InSAR).  Satellite gravity and altimetry measurements have in turn created a new paradigm for observing Earth’s changing shape and gravity field.  Geodetic instruments and techniques are also increasingly important to applications in other Earth science disciplines and beyond.  For example, GNSS is now used as a sensor for observing soil moisture, the ionosphere, and atmospheric water vapor, and is being leveraged for use in earthquake/tsunami early warning, surveying, and precision navigation. Geodetic measurements are moving relentlessly toward increasing resolution, higher accuracy, and more rapid acquisition.  This session will explore how advances in geodetic techniques have transformed the earth sciences and will continue to shape both science and society in the future.
