Figure 5 in Onset and duration of gray seal (Halichoerus grypus) molt in the Wadden Sea, and the role of environmental conditions

Figure 5. The proportion of visible molting seals in late-molt over time for the years between 2004 and 2010. The onset of molt varied per year: the earliest onset in 2009 and the latest onset in 2008. The bubble size indicates the number of animals with an observation quality score of 1 for each survey. The dashed horizontal line shows the 50% level and the vertical bold red and black dashed lines show at what day of the year 50% of the visible molting animals were in late-molt, respectively.
