A huge funnel was found on the seabed: a city block will fit in it

Giant "sinkholes" appear along the Arctic seabed in the Beaufort Sea, Canada. Scientists

They found out that this is due to the melting of permafrost. As a result, huge “pits” are formed, one of which can swallow an entire city block with six-story buildings.

The reason for the anomaly is not only climate change.Permafrost is melting due to heated, slow-moving groundwater systems. It has been underwater for about 12,000 years, since the end of the last ice age. Then the meltwater of the glaciers covered this region.

Despite the fact that the underwaterThe sinkholes are the result of long-term glacial-interglacial climate cycles; we know that the Arctic is warming faster than any region on Earth.

Until now, the frozen seabed was hiddenfrom the gaze of scientists. According to researchers, this remote part of the Arctic has only recently become accessible to research ships. All due to warming and retreating sea ice.

During the study scientists used botha shipborne sonar and an autonomous underwater vehicle (AUV) to perform high-resolution bathymetric surveys of the Canadian Beaufort Sea.
