Comparison between infrequent and frequent coastal polynyas. (a) Frequency distribution (FD) of annual maintenance days of coastal polynyas (bars), and the corresponding cumulative area (black line). Taking 120 d yr−1 as the boundary (grey dashed line), we classified coastal polynyas into low and high frequency, shown in blue and red respectively in all four subfigures. Their basic characteristics are also written in the figure. (b) Weekly total area of infrequent and frequent polynyas. (c) Weekly numbers of polynyas in the two categories. (d) Weekly mean area per polynya.
