Short summary
This study presents observations of brine descending from melting Arctic sea ice. The brine passed an under-ice turbulence instrument in plumes and was associated with very high heat fluxes. The salt flux indicates that the melting sea ice lost most of its salt content during the observations. The observations provide evidence of a desalination process not previously reported from drifting Arctic sea ice and is an important contribution to understanding ice–ocean interaction during melt.
