of a permafrost landscape How do you imagine an Arctic landscape characterized by permafrost? The answer is visualized by a 3-dimensional print of an Arctic landscape in Northeast Siberia, the Bykovsky Peninsula [...] ‘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 fieldwork involved in investigating [...] ice melts on slopes. As a result, sediments and plant remains are transported into rivers and the ocean, thereby changing the biochemistry of the water. The data were collected by Gonçalo Vieira und Pedro

As a consequence, the ocean is warming, sea levels are rising, sea ice concentrations are declining, and ocean acidity is enhancing (IPCC
