Gallery Muostakh Island is a slender crescent of land in the Laptev Sea with ice-rich Yedoma permafrost. The sun has set over Muostakh Island in the central Laptev Sea. A driftwood fire on the beach provides [...] provides warmth at the end of the summer as we ready to return to civilization. Since permafrost begins to degrade as soon as it is submerged, for example as the coastline retreats, we often work close

human activity in the Arctic takes place along permafrost coasts. These coasts have become one of the most dynamic ecosystems on Earth because permafrost thaw is now exposing them to rapid change: change [...] fates of organic matter released from thawing coastal and subsea permafrost; (2) assess what risks are posed by thawing coastal permafrost, to infrastructure, indigenous and local communities and people’s [...] system. NUNATARYUK is a H2020 project that investigates the impacts of thawing coastal and subsea permafrost on the global climate, and develops targeted and co-designed adaptation and mitigation strategies

The relative importance of these controls on the rate of sub-aquatic permafrost degradation, however, remains poorly understood. Therefore, the overarching science goal for the [...] the 2017 Bykovsky Spring Expedition was to evaluate the nature and distribution of subaquatic permafrost and taliks in multiple cryostratigraphic settings with drilling, sampling, near-surface geophysics
