Discussing the Relationship Between Organic Carbon and Cryostructures in Permafrost in a High Arctic Setting, Adventdalen Svalbard
The urgent ongoing contemporary climate change is drastically changing the Earth as we know it. In the Arctic, the climate is changing more drastically than the global average, and temperatures are rising significantly more. The phenomenon, known as Arctic amplification, is believed to happen by a c...

The urgent ongoing contemporary climate change is drastically changing the Earth as we know it. In the Arctic, the climate is changing more drastically than the global average, and temperatures are rising significantly more. The phenomenon, known as Arctic amplification, is believed to happen by a combination of albedo reduction, cloud-feedback, and temperature inversion. Another important, but often overlooked, factor in Arctic climate change is dust. Dust does not only cause albedo reduction but has also been found to host syngenetic permafrost in Adventdalen, Svalbard. As permafrost is both a sensitive and important carbon reserve, holding twice as much carbon as currently available in the atmosphere, it is of great importance to understand the carbon storage mechanism of it.
