In 2006 the National Science Foundation awarded Major Research Infrastructure (MRI) funding to UNAVCO and the IRIS/PASSCAL seismic consortium for a unique proposal to design and build a reliable power and communication system for autonomous polar station operation. This three-year development effort involves close collaboration with Antarctic seismologists and GPS scientists. Continuous, year-round seismic and geodetic measurements at remote sites will meet longstanding polar and global geoscience goals that have previously been unattainable.
Advances made during the first two years contributed greatly to successful deployments in Greenland and Antarctica, including large projects such as POLENET. Over 60 GPS and 40 seismic remote permanent stations have been installed, including five GPS and five seismic "science kits" provided under MRI funding to several PI's for installation at diverse Antarctic locations. During the third and final MRI field season, all technical goals were again realized thanks to intense efforts by the field team and the U.S. Antarctic Program support staff.
Milestones During Year 3 Field Season:
Figure 1 - GPS Plateau Testbed at South Pole Station. This system incorporates more efficient insulation, superior wind turbines, and improved thermal management. 16 channels of engineering data are being recorded here through winter 2009, including a side-by-side test of two wind modified turbines.
Figure 2 - GPS prototype station at Iggy Ridge in the Miller Range. This site, at the edge of the Polar Plateau at 84 degrees south experiences severe cold and extreme winds, and is a proving ground for wind turbine technology, structural designs, and thermal management.
Figure 3 - Five GPS and one GPS/seismic testbed stations installed near McMurdo Station represent a facility for proving advanced technologies under true polar conditions.
