Specific Character of Natural Hazards on High-latitude Sea Transport Passages Europe-Asia-Pacific Region: Challenges for Technosphere Safety
Abstract The especial feature of high-latitude marine routes is unusual geodynamic regime of the sea bed and hydrodynamic of waters, caused by a wide spread of a submarine permafrost, enriched with methane gas-hydrates. They had been accumulated during the Ice Age, and after deglaciation the both pe...
