Gas hydrates are inclusion compounds in which small hydrophobic guest molecules or atoms are trapped in cages formed by a network of hydrogen bonded water molecules. Of special interest is methane hydrate, known as "burning ice", as it occurs in large amounts in the sediments of the worldwide oceans and in the arctic permafrost regions. However, few detailed experimental studies have been conducted to explore how and when molecular organizations occur during the formation process. Here we use an in situ neutron reflectivity and laser light scattering techniques to study the water/gas interface where methane hydrate starts to form because of proximity to sufficient quantity of methane gas.
