The processes controlling the distribution of melt water
from the retreating ice edge in summer in the Chukchi Sea
were examined in order to provide evidence of the flow regime.
Current and salinity data from the National Oceanographic
Data Center (NODC) files and from four MIZPAC cruises
were utilized in this work. An increase in melt-water content
towards the ice in the approximately 30 km wide icemelt
zone as well as an abrupt salinity decrease were observed.
This effect was presumed to be due to scattering
of ice from a diffuse ice margin accompanied by melting.
North of the ice edge the fresh-water content was greater
2 than that of southerly water by an amount (150-200 gm/cm )
equivalent to the thickness of the ice cover. These findings
together with an independent comparison of transport times
and ice satellite data produce good evidence that the
current flows faster than the ice retreats during summer
in the eastern half of the Chukchi Sea.
