Project Grant 2320391

The National Science Foundation (NSF) Integrative Activities program awarded a $209,705 Project Grant to the University of Hawaii at Manoa to acquire a state-of-the-art isotope ratio mass spectrometer. This major research instrumentation (MRI) award will support Earth and ocean science research by integrating the new equipment into the university's existing stable isotope biogeochemistry laboratory. The instrument will be used primarily for isotope analyses of nitrate, nitrite, and ammonium, which are crucial for catalyzing new research capacity and supporting existing strengths in biogeochemistry in Hawaii. The award will also contribute to the university's educational goals by training researchers at all levels in stable isotope analyses through new collaborations, teaching efforts, and a "seed analysis" program. Additionally, the new mass spectrometer will support the research of three young faculty members, including two Native Hawaiian women. The isotopic analyses facilitated by this equipment will help address challenges related to nitrogen contamination of groundwater and nearshore environments in Hawaii and other Pacific islands.
