Ecogeochemistry has become a useful tool in studying foraging ecology of marine mammals and other consumers. Ratios of stable carbon (δ13C) and nitrogen (δ15N) isotopes in consumer tissues can reflect foraging history over longer time spans than traditional methods of dietary analysis. To better und...
