Gary Dwyer

Gary Dwyer is a Senior Research Scientist and Instructor in Earth and Ocean Sciences at Duke University, primarily affiliated with the Earth & Climate Sciences Division. His research focuses on environmental tracers in paleoceanography, paleoclimatology, and environmental geochemistry, with a strong emphasis on Arctic Ocean studies and tropical South America hydrology. He has contributed to understanding climate change impacts through proxy reconstructions and geochemical analyses of sediment cores.

Recent grants include Arctic Ocean ostracode geochemistry and paleotemperature studies. His work bridges geological and environmental sciences, addressing modern and ancient environmental systems. Notably, he has explored coal ash contamination and phosphate fertilizer impacts on soil and water quality, as highlighted in media reports on environmental tracers.

Publications span 20+ years, emphasizing Arctic paleotemperature records, Amazon climate history, and coal combustion residuals' environmental effects. Collaborations involve multidisciplinary teams analyzing isotopic data (Sr, Pb, B) to trace pollutants and reconstruct past climates. His research underscores the interplay between geology, climate, and human activity impacts on ecosystems.
