Estimates of trackline detection probability, <i>g</i>(0).

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 Estimates for Ziphius and Mesoplodon in sea states 2+ are from unpublished data (J. Barlow).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.各喙鲸（beaked whale）属的丰度估计值均为蒲福海况（Beaufort sea state）的函数。海况0至1的估计值与变异系数（coefficient of variation, CV）取自文献[21]。海况2级及以上的剑吻鲸属（Ziphius）与中喙鲸属（Mesoplodon）的估计值取自未发表数据（J. Barlow）。 *巴洛（1999）曾报告点估计值为0.96。本文报告的数值为巴洛自助法分布（bootstrap distribution）的均值，以与已报告的变异系数保持兼容。
