Table 2. Measured traveltimes and P-wave velocities estimated from laboratory data.

Notes: * = length was measured before and after the experiment; ** = corrected velocity is estimated by interpolating the change in sample length during the experiment (see text); P_c = confining pressure; P_p = pore pressure; P_e = P_c - P_p = effective pressure; † = the drained test was conducted before the undrained test for Section 149-899B-12R-4.
