To improve our understanding of mercury in the global environment, there is a critical need for an international effort to monitor mercury concentrations in air, water, and biota in both aquatic and terrestrial ecosystems. The Global Mercury Observation System (GMOS) would provide data needed for model validation, and for accurate future predictions of changing mercury emissions and ecosystem response at local, regional and global scales.
BRI's Global Biotic Mercury Synthesis (GBMS) database contains 1,835 mercury concentrations: 32,219 samples from 654 species of marine and freshwater fishes, marine mammals, and elasmobranchs. We have compiled data from peer-reviewed publications and government sources in a spatial-explicit format to better understand the extent and magnitude of mercury exposure in biota.
