What was the "sea" level during a snowball Earth?
Given that sea levels were about 120 metres lower during the last glacial maximum, where much of North America and Eurasia was covered in ice, and sea levels would rise by about 70 metres if all ice caps on earth melted, what would the sea level be when ice covered the entire globe during the Cryogenian period? The ice in Greenland and Antarctica is several kilometres thick, but it seems unlikely that the entire land area of Earth could be covered that thickly.
