The agency says a 10-year collaborative effort examined how maternal foraging strategies affect mercury transfer to offspring.

- USGS researchers studied mercury exposure in northern elephant seal pups before birth and its relationship to their mothers’ ocean foraging.

Why it matters: The findings described by USGS connect maternal foraging behavior with mercury exposure in seal pups in utero.
