Permafrost Change

Project "Permafrost Change" For most people, permafrost is a distant phenomenon that seems to have little to do with their own lives, making it hard for them to relate to. With the help of the resources [...] people have the chance to see, hear, touch and smell permafrost, thanks to original archaeological artefacts from the Ice Age and hands-on permafrost experimentation boxes. More over visitors can use a [...] virtual permafrost world. Lastly, ‘before-and-after’ lenticular images, together with video and audio recordings from expeditions to the Arctic, will help illustrate the thawing of the permafrost, and the

Characteristics of frozen sediments and ice structure therein inform how the permafrost deposits have been formed and transformed. Ice wedges can say something about the composition of

Subsea permafrost in the Arctic is generally relict terrestrial permafrost, inundated after [...] Why is it important? Submarine permafrost is similar to its terrestrial counterpart, but lies beneath the coastal seas. And as with terrestrial permafrost, subsea permafrost is a substantial reservoir and/or [...] of submarine permafrost and the influence of future climate system changes on submarine permafrost. Key lines of inquiry include: seasonal and interannual variability of sea floor permafrost boundary conditions
