The Arctic Ocean and circum-Arctic land masses are warming more rapidly than other locations on Earth, a phenomenon called the Arctic Amplification Effect.  A critical question is how this warming will affect temperature-sensitive gas hydrate deposits and methane dynamics at high latitudes.  Research focuses on the contemporary distribution of gas hydrates in marine and permafrost settings; the impact of warming since the end of the last glaciation on the development and degradation of subsea permafrost and associated gas hydrate; methane emissions to the atmosphere; subglacial hydrates; and interaction between the climate system and high-latitude gas hydrates.
