Permafrost is the term used for ground that is frozen solid year-round. When people refer to permafrost, though, they are almost always referring to permafrost thawing.. Geomorphology.

Permafrost stores a globally significant amount of mercury. . Water samples collected over six years from major Arctic rivers (. www.arcticgreatrivers.org. ) were analyzed using the MagLab’s record-setting 21T ultra-high-resolution Fourier-transform ion cyclotron resonance mass spectrometer. This magnet system’s resolving power is capable of determining elemental composition for tens of thousands of individual molecules in a single water sample. Combined with isotopic data, these formulae revealed both a common core amongst samples, as well as unique tracers of seasonality and a changing Arctic. .
