Annual mean freshwater budget of the Arctic, relative to a reference
salinity of 34.8 psu. The atmospheric box combines the land domain (the Arctic
terrestrial drainage) and the ocean domain. The boxes for land and ocean are sized
proportional to their areas. Transports are in units of km

.
The width of the arrows is proportional to the size of the transports (from Serreze et al.,
