Scope An increasing number of researches are focused on the natural gas hydrates system on the deep marine/lake and permafrost environments. Application of gas hydrates for material science and natural gas resources have also been a key issue and well developed recently. This session aims to discuss and improve recent topics and results from various researches associated with gas hydrates.
