Sea ice growth management
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 & icebergs
Sea ice thickening
Sea ice thickening is an idea to slow or reverse the decline of Arctic sea ice by artificially thickening it.
Sea ice breakup in winter
Sea ice can be an effective insulator between colder winter air and the warmer ocean below, thereby reducing the potential dissipation of heat into space.
Iceberg management
With rising Arctic temperatures, there have been major changes in iceberg production rates from marine terminating glaciers. These icebergs drift into warmer sea waters where they will slowly melt.
Modular iceberg creation by submersibles
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).
