Ice sheet mass loss is typically provided for grounded ice, because changes in floating ice are more difficult to measure and contribute minimally to sea level rise. However, net freshwater volume flow rate across ice sheet boundaries, including floating, ice is a better metric of ice sheet health.

Here we present total mass flows across ice sheet boundaries for both the Greenlandic and Antarctic ice sheets from 2010 through 2019. In addition to total mass flow, we provide constituent terms and gross rather than net values, including components that combine to provide surface mass balance (SMB).

Ice mass loss in Greenland is 330 ±50 Gt/yr which is ∼30% larger than the 255±40 Gt/yr grounded ice mass loss estimates that neglect floating ice changes. Ice mass loss in Antarctica is 450±270 Gt/yr which is ∼240% larger than the 190±115 Gt/yr grounded ice mass loss estimates. Freshwater mass flow rate from Greenland is ∼1065±120 Gt/yr or ∼3× mass loss (∼4× grounded mass loss), and from Antarctica is ∼3110±515 Gt/yr, or ∼7× mass loss (∼16× grounded mass loss).
