To evaluate the effect of climate change on the stability of methane hydrates in the seafloor, thermal conductivity measurements were performed in hydrate-bearing sediment. Using the renormalization and labeling technique methods, alongside of a thermal constants analyzer, the effective thermal conductivity (ETC) of methane hydrate-bearing sand and tetrahydrofuran (THF) hydrate-bearing sand were measured and found to be 1 W/mK and 2 W/mK, respectively. The thermal ...
