The University of Washington received a $389,919 Project Grant from the National Science Foundation's Division of Ocean Sciences (Geosciences program, CFDA 47.050) effective September 1, 2026, through August 31, 2029. This collaborative research initiative develops and applies uranium series dating methodology to pteropod shells—the calcium carbonate remains of planktonic sea snails—to establish absolute age determinations for marine sediment cores extending beyond the 50,000-year limit of radiocarbon dating. The researchers measure the decay of natural uranium to thorium in pteropod shells to calculate precise sediment ages, addressing critical gaps in paleoceanographic dating and enabling more accurate interpretation of temporal relationships between oceanic and terrestrial climate events. The project delivers scientific dating analysis applicable to approximately 2,000 existing marine sediment cores currently archived in U.S. research repositories, with an immediate focus on reconstructing the geologic history of the South Asian monsoon system. Secondary deliverables include maintenance of laboratory analytical capability in uranium isotope measurement, training of graduate students in advanced radiometric techniques, and public outreach programming designed to educate children and families on isotope geochemistry and natural radioactivity.Federal Grant Award Summary
