Measurements at |${P_{{\rm{eff}}}} = [ {5,\,\,15} ]$| MPa under a pore pressure |${P_{\rm{P}}} = 1.2$| MPa, showing the frequency dependence of Young's modulus E, Young's attenuation |$Q_{\rm{E}}^{ - 1}$|, and inferred elastic moduli in the fully glycerine-saturated sandstone sample at temperatures of (a)–(d) |${23^{\rm{o}}}\,{\rm{C}}$|, (e)–(h) |${10^{\rm{o}}}\,{\rm{C}}$| and (i)–(l) |${3^{\rm{o}}}\,{\rm{C}}$|. Solid curves in graphs (a), (e), and (i) represent a parametric fit to the experimental measurements based on the Kramers–Kronig relationship. Note that each symbol of open circle (ο) from Pair 1# and cross (×) from Pair 2# represents the mean measurement of three experiments, with corresponding error bars illustrated.
