Abstract
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 (<span classCombining double low line"inline-formula">D<2.3</span> m), and welding of pancakes forms the distribution of large floes (<span classCombining double low line"inline-formula">D>4</span> m).
