Researchers documented the formation of new, irregularly shaped, steep-sided depressions. The largest was an oval-shaped depression 28 meters (92 feet) deep, 225 meters (738 feet) long, and 95 meters (312 feet) wide. The research team attributes these changes to intermittent seafloor collapse due to the gradual warming of the permafrost sediment frozen beneath the Arctic Shelf since the end of the last ice age.
