Submarine Permafrost

s exist for parts of the Canadian Beaufort Sea, we know little about the distribution of submarine permafrost for most of the shallow Arctic Shelf, over 80% of which lies offshore of Eastern Siberia. [...] retreat and transgression, the evolution of permafrost beneath the sea floor, factors and processes determining the global distribution of submarine permafrost and the influence of future climate system changes [...] We need to know more about the current distribution and state of permafrost beneath the ocean, about what cause sit thaw, where and how quickly. This group addresses key questions surrounding permafrost
