Cornell University received a $348,300 Project Grant award from the National Science Foundation Division of Earth Sciences to investigate volatile evolution and decompression rates of high-intensity basaltic eruptions. Under the Geosciences program (CFDA 47.050), which supports basic research in integrated Earth system sciences, Cornell will conduct field and laboratory research over three years from July 2023 to June 2026. The university will analyze melt inclusions and reconstruct chemical histories to better understand magmatic conditions and decompression pathways leading to explosive basaltic eruptions. Researchers will also estimate decompression rates using numerical models and crystal textures. By studying volatile saturation, degassing, and pre-eruptive conditions in detail, the project aims to improve understanding of basaltic plinian eruptions and address correlations between decompression rates and eruption magnitudes. Findings will be incorporated into earth sciences courses and shared with the U.S. Geological Survey's Hawaiian Volcanic Observatory to support global volcano monitoring efforts. The award also provides research training for graduate and undergraduate students.
