On Earth with Brooke Hoppstock-Mattson - Environmental Geochemist

Brooke is an environmental geochemist that studies metal cycling by analyzing animal tissues and byproducts, known as biomonitors. By measuring lead isotopes and metal concentrations in biomonitors a more detailed picture of how metals move through the environment can be seen. Brooke works with honey from Vancouver, chum salmon from the Pacific ocean, and bowhead whale baleen plates from the Hudson Bay, all of which tell a unique story about metals in the various settings.
