Detailed Description

Maternal foraging strategies and pup mercury exposure. The tracking map (A) outlines the geographic paths of adult female seals using different foraging clusters. The chart (B) illustrates corresponding mercury concentrations in their pups' lanugo hair, demonstrating that open-ocean, deep-diving strategies (red) correspond with the highest mercury exposure.
