EarthScope, the nation’s primary seismological and geodetic data facility, was recently formed as the merger of UNAVCO, which held an archive for GPS data, and IRIS, which held a seismic data archive.

"The conversation we're having is, 'How much of this is transferable?'" said Sullivan, also a professor of civil, environmental and geodetic engineering.

“It was a big surprise to me,” says Jihye Park, a geodetic scientist at Oregon State University who was not involved in the research.

"The accuracy is so extraordinary that even today it continues to astound. It represents the first geodetic survey in the New World."

Some groups envisioned lines of sea-floor geodetic arrays off the coast, with wave gliders passing to collect data.
