Abstract

Muddy marine snowflakes initially settle faster than clean ones. Howeverthe strong circulation in the wake of a settling, muddy, marine snowflakeresults in the formation of a vortex ring and its subsequent rapid breakup intotwo or three smaller flakes. Their settling velocity is much smaller than thatof the original flake. Thus the addition of mud may actually slow down thesettling of marine snow in wetland-fringed coastal waters.
