Harbor seals (Phoca vitulina concolor) are widely distributed in the temperate coastal waters of the Gulf of Maine and are useful sentinels of food chain contamination because they occupy a high trophic level, are long-lived, and tissue samples can be obtained with relative ease. Elevated tissue bur...
