As of January 2013, the Transportable Array (TA) of USArray (http://www.iris.edu/USArray/, last accessed September 2013), the seismological component of EarthScope (http://www.earthscope.org/, last accessed September 2013), has extended east of the Great Plains and into the Midwest and Gulf Coast regions, offering routinely processed data for travel‐time inversions in regions where little data were previously available. In previous research notes (Burdick et al., 2008, 2009, 2010, 2012) we presented 3D tomographic models of mantle P‐wavespeed from global and USArray‐TA travel‐time data recorded through November 2007, December 2008, January 2010, and...
