Challenges for the Arctic Technosphere Safety: Specific Hazardscaused by Grounding the Super-Weight Gravitational Platforms on a Subaqual Permafrost
Abstract The especial feature of high-latitude productive fields on the Arctic shelves is unusual geodynamic regime of the subaqual frozen bases enriched by methane gas-hydrates.Permafrost layersinto bottom sediments had been formed during the Ice Age, and after deglaciation the both permafrost and...
