The National Science Foundation (NSF) awarded a $226,865 Project Grant under its Geosciences program (CFDA 47.050) to the University of Delaware. The grant will support the collection of high-resolution carbon isotope data on GO-SHIP cruises in the Indian and Pacific Oceans to better constrain ocean carbon uptake and storage. Specifically, the project will measure the ratio of carbon-13 to carbon-12 in dissolved inorganic carbon (DIC) using a new seagoing DIC extraction system coupled with a laser spectrometer. The data will be compared to prior datasets to quantify decadal changes in carbon-13, providing insights into upper ocean turnover and anthropogenic CO2 uptake rates. The project will train a graduate student and postdoctoral scholar in the collection and analysis of the carbon isotope datasets. The award period runs from February 15, 2025 to January 31, 2029.
