Scientists tried to thicken Arctic ice by pumping seawater onto it. The ice did become thicker and brighter, but there is a big catch
Scientists tested spraying seawater onto Arctic ice, which showed promising initial results. The treated ice became thicker and more reflective, resisting summer melting effectively. This method offers an alternative to controversial geoengineering approaches for ice preservation. While promising, researchers note significant challenges for large-scale implementation across the Arctic. Further work is essential before this technique can be consi…
First experiment to thicken Arctic ice with seawater shows promise — but there's a big catch
A simple method to thicken Arctic sea ice has shown promising results in its very first field experiment, performed in Cambridge Bay, Nunavut, Canada.Researchers are considering several controversial geoengineering techniques to slow the catastrophic melt of Arctic sea ice, including stratospheric aerosol injection, which involves shooting tiny sulfur particles into the sky to blot out the sun. But in a new study, scientists evaluated the merits…
Pumping seawater on the ice in winter to allow it to freeze in additional layers — a technique used for decades for ice roads and ice rinks. An initial field experiment conducted in Cambridge Bay, Canada, shows that this simple method can thicken the ice by 32 centimetres, [...]
