Project Highlights 2008 - POLENET Support 2007-2008

POLENET Support 2007-2008

  • Principal Investigator (PI): Terry Wilson, Ohio State University
  • UNAVCO Engineers: Thomas Nylen, Marianne Okal
  • Dates: December 2007 to February 2008
  • Location: Antarctica

Twelve continuous GPS and eight seismic stations were installed in Antarctica during 2007-08 field season. The POLENET Support project is part of the International Polar Year (IPY) POLENET consortium and includes active participation of collaborators from 28 nations including the US. The project's GPS goals are to measure the vertical and horizontal solid Earth deformation to improve and test the models of glacial isostatic adjustment/sea-level change and to improve the global geodetic reference frame.

13 people were deployed in Antarctica to install the GPS and seismic stations. CGPS sites were installed by helicopter or plane from McMurdo, Patriot Hills and Siple Dome. Data from these sites are transmitted via the Iridium satellite system to the UNAVCO Archive. Installation of another approximately 15 CGPS stations is planned for next season to complete the US portion of Antarctica GPS network.
