Comparison of dive characteristics reported here and from Cuvier's beaked whales tagged in other areas. All depths are in metres and all durations are in minutes. The method of calculating averages (mean, median) is stated with the number, when relevant. ‘Mean’ or ‘median’ indicate pooling of all individuals. ‘Group mean’ in Schorr et al. [3] indicates the mean of the individual medians. ‘Grand mean’ in Baird [42] indicates the mean of individual means. Deep dives were defined as follows: this study, greater than 800 m; Schorr et al. [3], K-means cluster analysis separating dive types; Tyack et al. [4] cluster analysis showing deep dives greater than 700 m; Joyce et al. [5], follows Tyack et al. [4] methods; Baird [42], greater than 800 m. n.a. indicates a metric was not given in the article.
