Susan A. Welch

Susan A. Welch works in geochemistry, studying how elements and nutrients like phosphorus, vanadium, and silicon move through water, sediment, and ice in environments ranging from agricultural streams and shale gas basins to Antarctic glaciers. Her work often combines field sampling, isotope analysis, and geochemical modeling to trace the sources and pathways of these substances. Much of her recent work has practical relevance to water quality, resource extraction (shale gas), and understanding past climate through ice and dust records.

Publication output has fluctuated over the last decade with a peak in 2020, followed by a somewhat slower and more variable pace in recent years averaging about 5 papers per year.
