Shared from Sam Carana 20 000 years ago, during the last glacial maximum, the sea level dropped to minus 120 meters. It means that today´s shallow shelf area was land. It was Siberia. And Siberia was frozen. The permafrost on the ocean floor today was established in that period. In other words, the permafrost off shore Siberia has been safely frozen for 20,000 years and now it is thawing! This basic education article does a great job of clarifying the conditions of the permafrost in offshore Siberia.
