When compressed by a depth of only a few hundred metres of water simple gases like air and methane combine with liquid water to make solids — gas clathrate hydrates. These compounds occur widely on the ocean floor and have long been known to fishermen who regularly haul up lumps of so-called ''hissing-ice’’ in their nets. Gas hydrates are a major focus for current research. They account for 30% of the Earth’s methane and are a major potential resource. Destabilisation of clathrate beds leading to a 'planetary burp’ is proposed as cause of the Permian-Triassic extinction event and is a potential consequence of runaway global warming. And gas hydrates provide a window into the properties of the water molecule — arguably the most important problem in condensed matter science. Werner Kuhs is a leading authority on gas hydrates and will talk about his work on these intriguing compounds.
Tea and cakes will be served from 1630 outside Lecture Theatre A.
Our General Interest Seminars are an opportunity for distinguished speakers to present new research in physics and related areas. The material presented is suitable for undergraduate level upwards and all members of the School are welcome to attend..
