Areal Coverage northeastern North America (latitude: 39.5°/47.7°; longitude: -76.2°/-67°)
 
Data Set Description This model includes Moho depth in two scales: 1) Moho depth values extracted from the common conversion point (CCP) stacking of teleseismic P wave receiver functions every 0.5 degree. 2) Interpolated Moho depth with the interval of 0.1 degree using triangulation-based cubic interpolation method. We obtained receiver functions from 688 high-quality earthquake events recorded by a total of 87 permanent and 109 temporary broadband seismic stations in this region (see Li et al., 2018 for details). Images of the extracted Moho are available in Li et al. (2018)
 
Supplemental Information
 

Distribution of three-dimensional Moho depth variations
Distribution of three-dimensional Moho depth variations. AA’, BB’, and CC’ correspond to three profiles. The black dashed lines mark the interpreted Grenville-Taconic, Taconic-Gander, and Gander-Avalon boundaries by Hibbard et al. (2006) and Karabinos et al. (2017). AV = Avalon; GA = Gander; TB = Taconic belt; GR = Grenville Province.
