The National Science Foundation (NSF) awarded a $165,829 Project Grant under the Geosciences program (CFDA 47.050) to the University of Oregon to conduct research on the transport dynamics and mobility of large-scale submarine volcaniclastic density currents produced by the 2022 eruption of Hunga Volcano in Tonga. This 3-year collaborative research project, scheduled to commence on September 1, 2024, will involve systematic sampling and mapping of the submarine volcanic deposits using remotely...
This $136,482 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funded a rapid bathymetric survey and related research activities to study the effects of the January 2022 eruption of Hunga Tonga-Hunga Ha'apai volcano in the Kingdom of Tonga. The University of Texas at Dallas, in collaboration with GNS Science of New Zealand, deployed the 28-meter research vessel R/V Kaharoa to map changes to the seafloor near the summit and flanks of the submarine caldera...
This $420,527 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to reveal the depth and volume of magma stored beneath 60 underwater volcanoes along the Kermadec-Tonga Arc. The project will use a novel method to detect magma from satellite altimetry data and create open-access software. It will also train an early-career PI and a postdoctoral scientist, and share the results through a digital atlas of submarine volcanoes. The...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $406,608.00 to the University of South Florida to conduct collaborative research on volcanism and tectonics in the Bight Transform region of the Mid-Atlantic Ridge. The project will use deep-sea robotic vehicles to map and sample submarine volcanoes near the Bight Transform Fault, with the goal of analyzing the sampled rocks to understand how oceanic crust and seafloor volcanoes form. The...
This $490,303 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support a research project aimed at improving the understanding of lava flow properties and their impact on volcanic eruption hazard assessment. The key products and services to be delivered under this award include: Developing and deploying two new field tools to directly measure the viscosity of natural lava flows, which contain critical elements like bubbles and crystals...
This Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), provides $518,808 to the University of Michigan to assess atmospheric impacts of the 2022 Hunga Tonga-Hunga Ha'apai volcanic eruption. The University will use observations and modeling to evaluate how the eruption affected Earth's energy budget, stratospheric temperatures and circulation patterns, and Antarctic ozone hole formation. Researchers...
This $312,574 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a 43-day seagoing dredging expedition to sample seamounts on top of the Ontong Java Plateau. The primary objectives are to study the interactions between deep mantle plumes and the overlying large, thick Ontong Java Plateau, and to test whether the passage of this volcanic structure over the Samoan and Rarotonga plumes approximately 60-30 million years ago resulted in...
This $256,426 Project Grant was awarded on May 1, 2025 by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of South Carolina. The grant supports a collaborative research project to investigate volcanism and tectonics in the Bight Transform region of the Mid-Atlantic Ridge, using deep-sea robotic vehicles to map and sample submarine volcanoes. The research team will analyze the collected rock samples to better understand the formation of oceanic crust and...
This Project Grant award of $655,938 from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project to conduct 3D multichannel seismic surveys at the East Pacific Rise volcanic system. The goal is to create high-resolution imagery that can be used to investigate how the magmatic and hydrothermal systems have changed over the past decade, providing insights into volcanic cycles on decadal timescales. The project will partner with industry...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $296,096 to Brown University provides funding to investigate the crust and uppermost mantle beneath active volcanoes using new seismic analysis techniques. The 2-year project, starting on Sep 1, 2024, aims to advance understanding of how magma storage and migration affect the eruptibility of volcanoes in regions like Yellowstone, the Cascades Arc, and the Altiplano-Puna Volcanic Complex. Key...
