A numerical model suggests that surface stress variations associated with a
lead may give a large-scale recirculation flow, Suspended ice crystals may
then be transported effectively down to the bottom, where such a flow is a
lso favorable for sediment entrainment. The model suggests that the ice cry
stals and sediment particles may coagulate effectively if a wind episode la
sts longer than about tu(*)/D similar to 30. (C) 2000 Elsevier Science B.V.
