[...] 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.
