Carbon Isotope Analysis of Individual Amino Acids in Freshwater and Marine Mammalian Hairs Based on High‐Performance Liquid Chromatography Separation and Purification: Implications for Aquatic Food Consumption in Archaeological Contexts

ABSTRACT Compound‐specific stable isotope analysis (CSIA) has been widely applied to modern and archaeological samples of animal and human body tissues to evaluate food habits and/or physiological conditions. However, these techniques have rarely been applied to aquatic mammals,...

A dynamic framework for marine radioactivity baselines: Climate-driven variability of 137Cs in the Pacific Ocean

Radiocesium-137 ( 137 Cs) is a useful tracer of ocean circulation because of its long physical half-life and relatively conservative behavior in seawater. We investigated variability in Pacific 137 Cs concentrations and apparent half-lives using observational datasets and numeric...
