Atsuko Yamazaki, Ph.D

Fields of Specialty: Carbonate Geochemistry, Marine biogeochemistry, Paleocenography
My research interests are marine nutrient cycles, carbonate production of coral reefs, and their connections to global climate change through the geological timescale. My approach is reconstruction of environmental and metabolic records in modern and fossil coral skeletons.
