![Site locations and hypothesized pan-Arctic glaciation. ODP Site 910 and MD99-2277 (red dots) are located in the Eurasian sector of the Arctic Ocean and central Nordic Seas, respectively. Site 910 lies just beyond the margins of the maximum MIS 2 Eurasian ice sheets [gray dashed line; based on (51)], while MD99-2277 was simultaneously covered by sea ice. However, both sites are hypothesized to have been fully glaciated under the maximum pan-Arctic ice sheet extent (white shaded extent with blue flow lines) proposed by Hughes et al. (75) [modified from Jakobsson et al. (7) and Geibert et al. (3)]. - Science Advances](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/07/Ice-World-Oceanography-The-Arctic.png?resize=1200%2C718&ssl=1)
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages.

During Snowball Earth Early Life May Have Sheltered In Meltwater Ponds
When the Earth froze over, where did life shelter? MIT scientists say one refuge may have been pools of melted ice that dotted the planet’s icy surface.
