Figure 2
Weekly Presence Comparison from 2004–2014: Boxplots representing the number of days per calendar week with confirmed North Atlantic right whale upcall acoustic presence in each region described in Fig. 4 and for each time period of interest (2004–2010 and 2011–2014). Horizontal lines within the boxes indicate the median, box boundaries indicate the 25th (lower boundary) and 75th (upper boundary) percentiles, vertical lines indicate minimum and maximum values, and black dots represent outliers. Grey blocks indicate time periods where no data were available for that region.
