The constant presence of permafrost is able to preserve the soft tissues of organisms through a process similar to freeze-drying. [1] With such complete preservation of tissues, it is possible to determine numerous things from the such as: DNA, eDNA, [ 2 ] evolutionary history, [ 3 ] gut contents, [ 4 ] and trophic dynamics.

Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
Terraria (/ t ə ˈ r ɛər i ə / ⓘ tə-RAIR-ee-ə [1]) is a 2011 action-adventure sandbox game developed by Re-Logic. The game was first released for Windows and has since been ported to other PC and console platforms.
The permafrost carbon cycle or Arctic carbon cycle is a sub-cycle of the larger global carbon cycle. Permafrost is defined as subsurface material that remains below 0 o C (32 o F) for at least two consecutive years. Because permafrost soils remain frozen for long periods of time, they store large amounts of carbon and other nutrients within ...

Stunning drone footage has revealed details of the Batagaika crater, a one kilometre long gash in Russia's Far East that forms the world's biggest permafrost crater. In the video two explorers ...
Methane emissions by the permafrost carbon feedback—amplification of surface warming due to enhanced radiative forcing by carbon release from permafrost—could contribute an estimated 205 Gt of carbon emissions, leading up to 0.5 °C (0.9 °F) of additional warming by the end of the 21st century. [17]
Permafrost tundra includes vast areas of northern Russia and Canada. [2] The polar tundra is home to several peoples who are mostly nomadic reindeer herders, such as the Nganasan and Nenets in the permafrost area (and the Sami in Sápmi). Tundra in Siberia. Arctic tundra contains areas of stark landscape and is frozen for much of the year. [5]
