A team of Skoltech researchers has published a series of three papers dealing with various aspects of how salt from the ocean water and other salts penetrate into frozen soil that contains gas hydrates—icelike crystals composed of water and gas, mostly methane. This so-called salt migration affects the rate at which permafrost melts as global warming advances. Taking that process into account is therefore necessary for accurate climate change modeling. The research findings are reported in papers dated June 27 and July 9 in the journal Geosciences, and in the July 5 paper in Energy & Fuels.
