Short summary
Short summary
Using a 1D coupled ice-ocean model, we quantified the effects of meltwater and ice-albedo feedback independently. The meltwater reduces melting by 19 % through thermal isolation, while ice-albedo feedback increases melting by 41 %, with nonlinear coupling between them. In winter, meltwater protects ice in weakly stratified areas by blocking Atlantic heat. Our study provides new insights into the relative importance of different components in the Arctic ice-ocean system.

Short summary
Meltwater is a critical factor affecting the upper Arctic Ocean, but there has been little research on its specific effects. By artificially removing meltwater from a column model, we found that reducing meltwater weakened ocean stratification and increased summer sea ice melting. The role of meltwater in winter sea ice formation varies by region – removing meltwater increased winter sea ice formation in areas with strong stratification, while decreasing it in areas with weak stratification.
