Abstract

A third sea-floor gas hydrate Natural gas hydrates — ice-like solids that consist of 'guest' molecules trapped in cages of water molecules — are a potential source of energy and may play a role in climate change and seafloor collapse. Experiments have shown that there are three common gas hydrate structures — sI, sII and sH — but only sI and sII hydrate have been found in the natural environment. Now sH hydrate (in close association with sII hydrate) has been identified in seafloor samples from Barkley canyon, 80 km off Vancouver Island. This complex gas hydrate can trap larger guest molecules than sI or sII, and is more stable than sI hydrate, indicating that gas hydrates could be more widely distributed than previously thought.
