Fig.13. a,b_ SAR-derived ice motion superimposed on the WWGS'92 buoy drift array, for periods a
July 14-17, 1992, and b July 13-16, 1992. Gridded geostrophic winds and mean climatological
geostrophic currents are shown together with the optimally interpolated ECMWF pressure field.
Buoy start locations are shown by diamonds. For further details, see text
