Governance - Eric Calais Candidate Statement

Over the past decade, UNAVCO has been a key to the success of GPS as a leading technique for measuring present-day crustal motions thanks to its state-of-the-art scientific and technical support to the community and open data policy. This, in turn, has allowed major advances in our understanding of lithospheric deformation, from global plate motions to earthquake processes.

An even more exciting time is ahead of us, with, as a highlight, the Plate Boundary Observatory now funded through the Earthscope initiative. As a consequence, UNAVCO will have to move to the next level of scientific and technical services to the community to fully exploit PBO and the other components of Earthscope. UNAVCO can reinforce its ability to incorporate new technological developments, for instance by taking advantage of current developments in computer and information science to manage, exchange, and process massive data sets such as those provided by the continuously growing permanent GPS networks. UNAVCO can also help the community benefit from new advances in precise positioning and deformation measurement techniques, such as GPS-seismology, sea-floor geodesy, and GNSS capabilities. Similarly, radar interferometry and optical correlation techniques have clearly proven their complementary value to GPS for deformation measurements. UNAVCO is clearly a worldwide leader in its field but there is a potential for further international interactions that would consolidate access to new data sources and promote technology transfer and training.

I am strongly committed to contributing to the further success of UNAVCO, Inc., by strengthening its ability to provide the best possible service to the community.
