Project Grant 2554178
- The National Science Foundation (NSF) Division of Earth Sciences awarded a $174,318 Project Grant to the University of Hawaii at Manoa (UH) under the NSF Geosciences program (CFDA 47.050) to establish the use of Raman spectroscopy for constraining the degree of calcium carbonate saturation in the calcifying fluids of marine calcifying organisms. This 3-year collaborative research project aims to generate Raman calibrations for magnesium content and carbonate saturation state that can be...
- This Project Grant award of $463,475.00 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate calcium isotope variations in ocean island basalts (OIBs) to better understand the deep Earth carbon cycle. The research aims to distinguish mantle source heterogeneity from magmatic processes that control calcium isotope signatures in OIBs. Key objectives include tuning phase equilibrium models to constrain magmatic processes, mantle source...
- This $548,713 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to understand the impacts of global warming and ocean acidification on Rocky Intertidal ecosystems. The project combines controlled laboratory studies, field experiments, and modeling to investigate how shifting environmental conditions and loss of foundation species affect ecosystem functioning in these communities. The research integrates opportunities for ecological and...
- The National Science Foundation Division of Ocean Sciences awarded the University of Hawaii $661,926 on July 1, 2026, under the Geosciences program (CFDA 47.050) to quantify urea as a nitrogen source to phytoplankton in the North Pacific Ocean. The project develops and validates analytical methods to measure urea concentration and cycling in surface waters near Hawai'i and U.S. Pacific territories, addressing a measurement gap that has prevented direct quantification of urea's bioavailability to...
- This $200,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to investigate the impact of changes in seawater carbonate chemistry, such as ocean acidification, on shell formation in tropical marine bivalves. The research will be conducted at the State University of New York, College of Environmental Science and Forestry (SUNY ESF) and the University of Hawai'i, Hilo. The project aims to identify the specific carbonate...
- 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...
- The National Science Foundation (NSF) Division of Ocean Sciences awarded a $158,324 Project Grant under the Geosciences program (CFDA 47.050) to the University of Hawaii (UH) to characterize the effects of ocean alkalinity enhancement (OAE) on coral reef ecosystems and atmospheric carbon dioxide. The research project aims to: 1) quantify the dissolution rate of olivine minerals used in OAE and their impact on reef communities and carbon dioxide levels; 2) develop biogeochemical models to predict...
- The University of Hawaii at Manoa was awarded a $499,996 Project Grant from the National Science Foundation Division of Earth Sciences. The grant supports research titled "Structure and Thermal Elastic Properties of Calcium Silicate Perovskite" from September 1, 2021 to August 31, 2024. The research aims to strengthen fundamental knowledge and understanding of the integrated Earth system through basic research in the geosciences, as outlined in the National Science Foundation's...
- The University of Hawaii at Manoa was awarded a $912,167 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to characterize key components of biological carbon cycling in the Pacific Ocean through March 2026. Under the award, the university will use profiling floats equipped with oxygen and particulate carbon sensors to measure production and respiration rates across the Pacific Ocean on a daily basis and over all seasons. Ship-based measurements will also...
- This three-year Project Grant from the National Science Foundation Division of Ocean Sciences provides $507,547 to the University of Hawaii at Manoa to conduct research titled "COLLABORATIVE RESEARCH: ISOTOPIC INDICATORS FOR MECHANISMS OF ORGANIC MATTER DEGRADATION UNDER HIGH PRODUCTIVITY AND HIGH CARBON FLUX CONDITIONS (EXPORTS)." The research aims to develop isotopic indicators to study organic matter degradation under conditions of high biological productivity and carbon flux in...
The National Science Foundation Division of Earth Sciences awarded the University of Hawaii $464,052 on August 1, 2026, under the Geosciences program (CFDA 47.050) to conduct experimental research on elemental uptake in marine calcium carbonate minerals for paleoenvironmental applications. The project derives robust functional relationships between elemental incorporation into calcium carbonate and the physical and chemical conditions of mineral precipitation in seawater. Researchers will produce both calcite and aragonite—two common calcium carbonate polymorphs—in artificial seawater under controlled conditions, systematically varying temperature, salinity, pH, and calcium and total dissolved inorganic carbon concentrations to measure simultaneous uptake of paleoceanographically relevant elements. The resulting benchmark datasets will enable comparison of elemental impurities in calcium carbonate biominerals and clarify how biological factors during biomineralization influence the validity and accuracy of paleo-proxies used to reconstruct past marine environments. The award funds student mentoring—both undergraduate and graduate—and development of new online outreach materials for school students. Work is performed in Honolulu, Hawaii, with a period of performance from August 1, 2026, through July 31, 2029.
