EarthScope is the largest geophysics research project ever attempted and that requires a lot of people. Over 150 geophysicists have been given grants by the National Science Foundation to conduct cutting edge research using EarthScope instruments and data.
But they couldn't do it alone. Dozens of installers have driven backhoes to dig the holes into which instruments are placed; computer programmers have designed the servers that store the research data from EarthScope experiments; undergraduate students have explored every state in the union searching out appropriate sites for long-term instrument deployment; packers and shippers insure that equipment is delivered in working order to experiment sites; and education and outreach professionals explain EarthScope science to non-scientists.
