| In: | Earth's Cryosphere. (2003.), Special issue (2003) |
| Abstract: | Investigates thickness of offshore permafrost on eastern Laptev Sea shelf and compiles schematic map of its distribution. Presents computer modelling based on specified paleogeographical scenario and geological model for last glacioeustatic cycle. Uses new computational scheme and refined data to derive more precise distribution of permafrost in eastern part. Calculated thickness of ice-bonded permafrost increases northwards for given sea depth and decreases with increasing sea depth, reaching maximum of 450-520 m. Describes ongoing permafrost degradation due to geothermal heat flow since last 18 kyr BP. Concludes layer of cryotic deposits 70 to 120 m thick underlies permafrost. |
