- •
Thermal conductivities of methane hydrate-bearing sediments measured using the transient plane source method.
- •
Thermal conductivities of the sediments show weak negative dependence on temperature.
- •
The thermal conductivities of the sediments show strong dependence on morphology.
- •
Even small amounts of hydrates significantly enhance thermal conductivity in partially water-saturated, gas-rich samples.
- •
In samples with high water concentrations, thermal conductivity does not change significantly with hydrate saturation level.
