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

Permafrost
The fate of permafrost - soil that is frozen for 2 or more years - is of huge importance for the global climate because of the large amounts of organic carbon stored in it, which can be released

And secondly, we measured [...] elevations using a high-accuracy GPS antenna to estimate surface subsidence resulting from thawing permafrost. In addition, we visited research sites of local and international partners and discussed scientific
