Scholar-generated biography
Daniel Schrag's research focuses on Earth's climate history, particularly the Neoproterozoic snowball Earth hypothesis, carbon cycle dynamics, and paleoceanography. His work explores global climate change through isotopic analysis of carbonate minerals, carbon-isotope records, and deep-sea sediment studies. Schrag investigates the impact of major extinction events, such as the end-Permian extinction, on the carbon cycle and ocean chemistry. He also examines the role of deep-sea carbon storage and the oxygen isotopic composition of seawater during key climatic periods. His research integrates geochemical and paleoclimatic data to understand long-term climate feedbacks and their implications for modern environmental challenges.
