with an upward measuring system to get the ice thickness...
and guess what...
The ice is much thicker than previously thought....

A new type of 3D mapping revealed Antarctic sea ice could be much thicker than previously estimated, shows a study done with the help of a yellow robotic submarine named SeaBed.
The new study, published in Nature Geoscience, showed that average ice thickness in Antarctica is between 1.4 meters and 5.5 meters. The maximum thickness recorded was 17 meters.
Also, 76 percent of the mapped ice has been tagged as deformed, the study stated, which means that ice crashed together, forming a thicker layers of ice.
