David Harwood

David Harwood is a Professor in the Department of Earth and Atmospheric Sciences at the University of Nebraska-Lincoln, where he conducts cutting-edge research on Antarctic paleoenvironments and ice sheet dynamics. His work focuses on understanding past climate change through siliceous microfossils like diatoms and silicoflagellates, particularly in the context of the ANDRILL Program and IODP Expeditions. He teaches courses emphasizing field geology and laboratory skills in stratigraphy and micropaleontology.

• Research Focus: Paleoclimatology, Glaciology, Micropaleontology
• Key Projects: ANDRILL, SHALDRIL, IODP Expedition 374
• Teaching: Field geology, Stratigraphy, Micropaleontology

His recent publications analyze Antarctic ice sheet sensitivity to climate forcing, subglacial lake sedimentology, and Cretaceous-Paleogene extinction impacts on marine microfossils, spanning 2025-2014 with a focus on the Ross Sea and West Antarctic Ice Sheet dynamics.

Harwood's work bridges geological history with modern climate challenges, including the SWAIS 2C Project assessing ice sheet stability under +2°C warming. He also contributes to science education through inquiry-based Antarctic field programs.
