- The National Science Foundation Division of Ocean Sciences awarded Oregon State University $499,008 for a Project Grant on March 15, 2026, under the Geosciences program (CFDA 47.050). The project conducts high-resolution 40Ar/39Ar age-determination experiments on lava samples from the Manihiki and Hikurangi plateaus to establish the timing and duration of their emplacement and test whether eruptions from Ontong Java Nui, a massive large igneous province, coincided with and potentially caused...
- The National Science Foundation (NSF) Division of Earth Sciences awarded the Berkeley Geochronology Center (BGC), a non-profit organization, a $138,373 Project Grant under the Geosciences program (CFDA 47.050) to reconstruct southern Caribbean climate variability using coral and speleothem proxies. This 3-year grant, awarded on September 1, 2023, will support BGC's research to generate precisely dated records of local temperature and aridity from reef ecosystems and cave environments on the...
- The National Science Foundation Division of Earth Sciences awarded Carnegie Institution of Washington $401,892 on October 1, 2026, under the Geosciences program (CFDA 47.050) to conduct statistical analysis and numerical modeling of Earth's magnetic field during the period when the planet's inner core began to solidify, approximately 700 to 550 million years ago. The project will analyze paleomagnetic intensity and directional data from open-source databases covering the period around inner core...
- This $359,899 Project Grant was awarded on September 1, 2023 by the National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences under the Geosciences (CFDA 47.050) program. The grant supports a collaborative research project between researchers at Vanderbilt University and other institutions to reconstruct climate variability in the southern Caribbean region using coral and speleothem (cave) paleoclimate proxy records. Key objectives include: Generating geochemical records of...
- Federal Grant Award Summary The National Science Foundation's Division of Earth Sciences awarded Carnegie Institution for Science a $417,152 Project Grant (CFDA 47.050 – Geosciences) effective September 1, 2025, through August 31, 2028, to conduct collaborative research on volatile-carrying minerals and fluid transport in subduction zones. The primary deliverables include simultaneous in situ electrical and vibrational spectroscopic measurements on seven hydrous silicates and carbonates using...
- 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...
- The National Science Foundation awarded a two-year Project Grant of $174,000 to researchers at the California Institute of Technology to develop a new technique for determining eruption timescales applied to Large Igneous Provinces and climatic events over Earth's history. The grant is part of the Geosciences program (CFDA 47.050) to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Researchers will receive funding from...
- The National Science Foundation Office of Integrative Activities awarded the University of South Carolina $392,815 under the Geosciences program (CFDA 47.050) on January 1, 2027, to analyze mantle sources of large igneous provinces through comparative study of the Siberian Traps and Deccan volcanic provinces. The research examines geochemical differences between the two largest Phanerozoic volcanic eruptions, focusing on how competing deep mantle sources versus shallow crustal processes drive...
The National Science Foundation Division of Earth Sciences awarded Carnegie Institution of Washington $224,419 on September 1, 2026, under the Geosciences program (CFDA 47.050) to establish high-precision eruptive chronology for the Caribbean Large Igneous Province and determine its relationship to oceanic anoxic events. The project combines chemical abrasion–isotope dilution–thermal ionization mass spectrometry (CA-ID-TIMS) U-Pb zircon geochronology with re-osmium isotope stratigraphy, platinum-group element geochemistry, zircon trace-element chemistry, and hafnium isotopes to constrain the timing, duration, and eruptive rates of Caribbean LIP magmatism. U-Pb dating of volcanic units, including ash layers interbedded with ocean drilling cores and Colombian field sections, will establish the chronology. Re-Os isotopes and platinum-group element systematics from associated sediments will track volcanic inputs and marine anoxia development. The integrated geochemical and geochronologic framework will test whether Caribbean LIP volcanism directly drove carbon cycle perturbations associated with Oceanic Anoxic Event 2 or exerted stronger influence during Oceanic Anoxic Event 3, and will distinguish mantle plume from arc-related magmatic sources to provide insight into tectonic evolution. The award runs through August 31, 2029, with place of performance in Washington, DC.
