The Russian sector of the arctic shelf is the longest in the world. Quite a lot of places of massive discharge of bubble methane from the seabed into the water column and further into the atmosphere were found there. This natural phenomenon requires an extensive complex of geological, biological, geophysical, and chemical studies.

- * New research indicates that the ice-bonded permafrost in the ESAS has been moving downward by approximately 14 cm each year over the last 31-32 years, contradicting earlier beliefs about long-term stability post-inundation.
- * The presence of thermokarst patterns and gas migration suggests ongoing changes in the subsea environment, highlighting the need to understand permafrost degradation to predict future methane release accurately.
The hypothesis of a km-thick ice shelf covering the entire Arctic Ocean during peak glacial conditions was proposed nearly half a century ago. Floating ice shelves preserve few direct traces after their disappearance, making reconstructions difficult. Seafloor imprints of ice shelves should, however, exist where ice grounded along their flow paths.
