This National Science Foundation Project Grant award of $240,688 will fund research into the effects of recent seismic activity on hydrothermal vent circulation and iron export at the Kama'ehuakanaloa underwater volcano (formerly known as Lō'ihi) located approximately 30 miles south of Hawaii's Big Island. Awarded to Woods Hole Oceanographic Institution under the Geosciences program (CFDA 47.050), this project will use a deep-diving robot to investigate whether lava was erupted on the seafloor...
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...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $230,516 to the University of Utah to characterize the spatial and temporal variations of volcanic rift zones on basaltic shield volcanoes in Hawaii. The project aims to obtain detailed subsurface imaging of the rift zones at Kilauea and Mauna Loa volcanoes, which is essential for volcanic hazard mitigation. It will collect seismic data, including a follow-up survey to one conducted after...
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 $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 National Science Foundation Geosciences (CFDA 47.050) project grant award of $292,742 to the University of Houston System will fund collaborative research to re-evaluate magma storage depths and the origin of chemical variability in volcanic systems in the Cascade region. The key products of this 3-year project include: Measuring the volatile contents, including CO2, in olivine-hosted melt inclusions to better constrain magma storage depths in the Cascade region and gain insights into...
This $158,481 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research by Lehigh University to investigate the relationship between changes in glaciers, topography, and the behavior of active volcanoes in Chile over the past 50,000 years. The research aims to generate high-resolution records of volcanic activity, ice retreat, and landscape evolution, and use this data to explore how crustal loading changes driven...
This National Science Foundation (NSF) Division of Earth Sciences Project Grant, funded under CFDA 47.050 Geosciences, provides $180,000 over 2 years starting August 1, 2023 to explore the significance of spatial field data from integrated satellite remote sensing and GPS time series for machine learning and volcanic early warning applications. The project aims to integrate data from satellite radar, GPS, and high-resolution digital elevation models to generate 3D time series of surface...
This $523,946 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research linking helium isotope ratios with eruptive behavior at recent volcanoes in Hawaii, Iceland, and the Canary Islands. The awardee, Woods Hole Oceanographic Institution, will extract helium from lava samples spanning eruptions at Kilauea volcano (2018), Fagradalsfjall volcano (2021), and Cumbre Vieja volcano (2021) to establish time series of helium isotope ratios. The researchers will compare these ratios with other geochemical data and remote sensing metrics including ground deformation, seismicity, sulfur dioxide emissions, and lava discharge rates. The goal is to determine if variability in helium isotope ratios relates to magma recharging from the mantle, which could justify real-time helium isotope monitoring to improve volcanic hazard forecasting. The award also supports undergraduate and graduate student involvement and education outreach activities.
