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 MRI Year 1 development and field season contributed greatly to successful large deployments in Greenland and Antarctica, under projects such as POLENET. Approximately 45 GPS and 25 seismic remote permanent stations were installed, including five GPS "science kits" provided under MRI funding to several PI's for installation at diverse Antarctic locations.
During the Year 2 MRI season, all technical goals were again realized thanks to intense efforts by the field team and assistance from the U.S. Antarctic Program logistics providers and support staff. Five new testbed or prototype systems were deployed in Antarctica and four existing prototype stations were upgraded, each serving a specific function in developing technologies or optimizing deployment.
