Plan to Refreeze Arctic Sea Ice Shows Promise in First Tests

Field trials indicate that pumping seawater onto the snow on top of Arctic sea ice can make the ice thicker, offering a possible way to preserve sea ice throughout the summer. The bold plan could offer humanity a final chance to save the region’s vanishing sea ice, reports New Scientist.

Field trials conducted this year in the Canadian Arctic to thicken sea ice using water from the ocean below have proved successful, says UK start-up Real Ice. The startup believe their technology might help restore rapidly melting Arctic sea ice, which has fallen by half since the 1980s.

They are developing a system to create new layers of ice, in the hopes of protecting this vital ecosystem.
