- This Project Grant, awarded by the National Science Foundation (NSF) Division of Environmental Biology under the Biological Sciences program (CFDA 47.074) on July 15, 2025, supports a collaborative research initiative totaling $411,079 through June 30, 2030. The primary deliverable is a multi-scale, multi-proxy investigation examining how marine nutrient availability during the Tonian Period (1000-720 million years ago) may have driven eukaryotic diversification and ecosystem transformation. The...
- The National Science Foundation Division of Ocean Sciences awarded a $131,201 Project Grant to the University of California Santa Cruz (UCSC) under the Geosciences program (CFDA 47.050) to investigate and develop compound-specific isotope analysis of amino acids (CSI-AA) to better understand the species-level ecology of planktonic foraminifera. The goal is to use CSI-AA from shell-bound organics to refine inferences about foraminifera's depth habitat, diet, and symbiosis in order to improve...
- This $163,915 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project investigating changes in carbon uptake and storage in the Pacific Ocean during the Pliocene, a warm period approximately 3 million years ago. The primary objectives are to quantify the marine carbon response to temperature-sensitive mechanisms within the ocean, with the goal of better predicting carbon storage during future climate warming. The...
This $358,360 Project Grant, awarded April 15, 2026, by the National Science Foundation (NSF) Division of Ocean Sciences under the Geosciences program (CFDA 47.050), supports collaborative research to improve amino acid racemization (AAR) geochronology methods for dating ancient marine shorelines. The primary deliverable is the calibration and standardization of AAR dating techniques by analyzing approximately 100 globally distributed, independently dated Last Interglacial sites (approximately 125,000 years old). Researchers will establish temperature-dependent isochrons and develop complementary dating tools for samples approximately 40,000 years old, utilizing post-depositional temperature histories estimated from climate model simulations on a ~200 kilometer global grid. The project will emphasize measurements of intra-crystalline amino acid fractions to enhance reliability and minimize contamination effects, with findings applicable across diverse geographic regions. Northern Arizona University, the award recipient, will deliver a publicly accessible framework and interactive tools designed to facilitate shoreline age determination across additional regions globally. The research will generate empirical D/L (aspartic acid/leucine) to temperature relationships, improved understanding of taxonomic effects on dating accuracy, and standardized methodologies for marine mollusk shell analysis. Completion is scheduled for March 31, 2029. These deliverables will advance understanding of ice-sheet stability, coastal change, land uplift, and related natural hazards while supporting STEM student training and strengthening access to specialized research facilities.
