Panels at left are current velocity time-depth cross-sections, with speeds indicated by the colour scale at right. Superimposed black lines show ice floe velocity, with positive values indicating eastward (northward) motion. Charts at right show relative ice motion and water circulation at four depths, starting at coordinates 0,0. Simultaneous tracks of three ice islands are also shown (for S2 only). Water circulation tracks were determined by summing incremental velocities. See Figure 6 and 7 for site locations.
