Re-Thickening Arctic Sea Ice (RASi)
This project aims to assess the feasibility and impacts of sea-ice thickening by pumping seawater onto a small patch of sea ice.
Researchers will pump seawater from beneath existing ice which will then spread across the surface. They hope to learn whether this could help thicken the sea-ice and slow its melt.
Ice
Seawater
A strainer prevents fish from entering the pump.
Sea depth of at least 10m
Note: The outdoor experiments funded by the Advanced Research and Invention Agency (ARIA) will only go ahead after environmental impact assessments and public consultations, and with independent oversight.
