Finger-Rafting in Fresh-water Ice: Observations in Lake Superior
Finger-rafting, similar to that reported in sea ice, is common in thin (2-15 mm) new ice on Lake Superior. It is produced by wind traction alone; neither wave action nor brine is necessary for its initiation or propagation. Fingers have been observed to progress at rates of 0.5-5 cm/s.
