WebJun 13, 2024 · The albedo of pond is significantly smaller than that of snow and ice, which will lead to more solar energy flux into the ice and ocean beneath it. This causes the melt pond to melt further and then reduce the albedo [1,2]. Such an albedo feedback mechanism is one of the reasons for the rapid decrease in Arctic sea ice in summer.
