aApproach 1 assumed a one-to-one proportional relationship between sea ice and abundance. Approaches 2 and 3 estimated global and ecoregion-specific relationships between sea ice and empirical estimates of abundance, respectively. Results from each approach are shown for the mean and 95th percentile of estimated GL.
