Trench Axis Geometries for Global Subduction Zones (investigators Dan Bassett and Tony Watts)
These files contain the along-strike locations of the deepest points of the trench axis. The points are at 10-15 km increments along strike. The data files are ASCII text files of longitude and latitude. These trench axis geometries were used in the residual gravity/bathymetry studies cited in Bassett and Watts, 2015a,b.
