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.

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.
Pykrete is a 6:1 mix of ice and sawdust that has the property of melting slower than regular ice. Several references have been made online to the use of pykrete as an artificial barrier, as artificial sea ice, or as blockers of moulins.
Apart from thickening sea ice by directly adding mass to it (see sea ice thickening), it has been suggested that the ice could also be protected by increasing its albedo and thereby reducing the amount of absorbed energy (Field et al. 2018).
