EventIn Cambridge Bay, Canada, a Real Ice pilot pumped ocean water onto melting sea ice, instantly freezing it and adding about 50 cm to a 450‑m square patch. Funded by a £3.5 million UK grant, the work—supported by local Inuit guides—shows slower melt and higher reflectivity, hinting at a possible geoengineering tool to curb summer loss.
Scientists in Cambridge Bay pumped seawater onto melting ice, thickening a 450‑meter square patch by about 50 cm and slowing its melt—an early test of geoengineering that could help curb the Arctic’s rapidly shrinking sea ice while involving local Inuit communities.
A pilot geoengineering project near Cambridge Bay, Canada, pumped 50,000 tonnes of seawater onto Arctic sea ice, adding about 50 cm of thickness and brightening the ice, according to measurements taken by Real Ice and university scientists. The experiment, funded by the UK government, has local Inuit community support and is being examined for ecological effects and scalability through autonomous underwater drones.
