This $297,369 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research evaluating the contribution of small eukaryotes to nitrate-based new production in the North Pacific Subtropical Gyre. Over a three-year period ending November 2025, the University of Hawaii at Manoa will conduct laboratory and ship-based research to better understand how phytoplankton access subsurface nitrogen in surface waters during summer months. Researchers will sort phytoplankton by size and pigment composition, analyze stable nitrogen isotope ratios, and conduct metatranscriptomic analysis to investigate physiological pathways used for nitrogen uptake among different populations. This work aims to resolve the relative contribution of nitrate mixed from deeper waters to surface production, identify key plankton groups supporting nitrate-based production, and evaluate seasonal trends in nitrate contributions to total nitrogen production. The award also supports graduate students and postdoctoral researchers conducting the research.
