DESCRIPTION:The frozen regions of Earth\, such as the Antarctic and Greenl
 and ice sheets\, are displaying rapid and significant responses to climate
  change. As temperatures rise\, ice melts and sea level rises\, with conse
 quences that already impact people’s lives. Although Earth’s polar reg
 ions may seem remote\, changes there inevitably go on to influence populat
 ions and natural systems the world over.\n\n \n\nGeophysics is a fundament
 al tool used to provide information about the state of the frozen regions:
  how and why they are changing and what they might look like in the future
 . Cryoseismology is rapidly becoming part of this toolbox. Observations of
  seismic signals from glaciers and ice sheets are providing information ab
 out ice rheology and dynamics\, ice fracture\, and subglacial systems. All
  these factors control ice flow and therefore the contribution of the pola
 r regions to sea level rise. In this talk I will give an overview of how t
 hese measurements are made\, what they are telling us\, and how new techno
 logies such as seismic nodes will likely shape this exciting and challengi
 ng area of geophysics.
