Estimates for each beaked whale genus are a function of Beaufort sea state. Estimates for sea state 0–1 and CV are from [21]. Estimates for Ziphius and Mesoplodon in sea states 2+ are from unpublished data (J. Barlow).

^*Barlow (1999) reported a point estimate of 0.96. Value reported here is the mean of Barlow's bootstrap distribution, for compatibility with the reported CV.
