In 2019, an Indonesian design team came up with the idea of a submersible device that could take in sea water, desalinate it, and then have it freeze into a solid block they called a “new ice baby” (Griffiths, 2019).
Similar to other ideas to pump water on sea ice (see Sea ice thickening), engineer Sev Clarke (Planetary Restoration n.d.) and engineering student Katy Cartlidge (University of Cambridge 2022) both came up with designs to artificially produce sea ice.
In 2010, Veli Albert Kallio suggested the use of ‘floating cables or levees, even platforms’, to act as ‘seeding points to fasten the seasonal growth of the Arctic Ocean's sea ice’ (Geoengineering Google Groups n.d.)
Sea ice thickening is an idea to slow or reverse the decline of Arctic sea ice by artificially thickening it.
