"This file contains thermal property data for sII THF hydrate below -2.5 degrees C, as published in:" "Waite, W.F., Gilbert, L.Y., Winters, W.J., and Mason, D.H., 2006, Estimating thermal diffusivity and specific heat from needle probe thermal conductivity data, Review of Scientific Instruments, 77, 044904, doi:10.1063/1.2194481." The nonlinear results above -7.4 degrees C are published in: "Waite, W.F., Gilbert, L.Y., Winters, W.J. and Mason, D.H., 2005, Thermal property measurements in Tetrahydrofuran (THF) hydrate and hydrate-bearing sediment between -25 and +4¡C, and their application to methane hydrate, Paper 5042 in: Fifth International Conference on Gas Hydrates, Trondheim, Norway, Tapir Academic Press, vol. 5, 1724-1733." Measurement uncertainties for data excluding the nonlinear -2.5 to 3¡C data: Thermal Conductivity: ± 1% Thermal Diffusivity and Specific Heat: ± 3% "Measurements in the nonlinear regime are an indication of a phase change, and do not represent an intrinsic thermal property."
