Figure 1

Temporal representation of baleen Δ14C and δ13C in baleen plates. This figure has been modified from Eisenmann, et al.31. Each horizontal zone is created using location-specific isotopic estimates consistent with prey values and trophic fractionation (if applicable). The whale isotopic data plots within the zone appropriate to provisioning location. Isotopic zones: Australian prey – merged (dotted line), Antarctic prey (dashed line).
