Brief communication: Pancake ice floe size distribution during the winter expansion of the Antarctic marginal ice zone
The size distribution of pancake ice floes is calculated from images acquired during a voyage to the Antarctic marginal ice zone in the winter expansion season. Results show that 50 % of the sea ice area is made up of floes with diameters of 2.3-4 m. The floe size distribution shows two distinct slo...

Summary: | The size distribution of pancake ice floes is calculated from images acquired during a voyage to the Antarctic marginal ice zone in the winter expansion season. Results show that 50 % of the sea ice area is made up of floes with diameters of 2.3-4 m. The floe size distribution shows two distinct slopes on either side of the 2.3-4 m range, neither of which conforms to a power law. Following a relevant recent study, it is conjectured that the growth of pancakes from frazil forms the distribution of small floes ( D<2.3 m), and welding of pancakes forms the distribution of large floes ( D>4 m). |
