The research team will investigate the contributions of the upper mantle to Walvis Ridge volcanism, the factors determining the proportions of upper mantle versus hotspot contributions, and how the upper mantle changes as...
This National Science Foundation (NSF) Division of Ocean Sciences Project Grant award of $202,781 to Towson University is focused on understanding the evolution of the Tristan-Gough-Walvis Ridge hotspot system. Through collaborative research with national and international scientists, the project will investigate the contributions of the upper mantle versus the hotspot to the Walvis Ridge volcanism, and how the upper mantle changes as continental rifting and ocean basin formation progressed in...
The National Science Foundation (NSF) awarded a $145,872 Project Grant under the Geosciences Program (CFDA 47.050) to the University of South Florida (USF) to investigate volcanism and tectonics in the Bight Transform region of the Mid-Atlantic Ridge. The project will utilize deep-sea robotic vehicles to map and sample submarine volcanoes near the Bight Transform Fault, with the goal of understanding the formation of oceanic crust and seafloor volcanoes. The research will analyze the collected...
This two-year, $388,669 project grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research analyzing sediment and basalt core samples from the International Ocean Discovery Program Expedition 391. The University of Houston will collaborate to study the paleolatitude record of Walvis Ridge hotspot volcanoes in the late Cretaceous and early Cenozoic eras. Researchers will produce a paleolatitude timeline for comparison...
The University of South Carolina was awarded a $124,073 Project Grant from the National Science Foundation's Geosciences Program (CFDA 47.050) on May 1, 2025. The grant will fund collaborative research to investigate volcanism and tectonics in the Bight Transform region of the Mid-Atlantic Ridge between 55.5°N and 57.0°N. 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 better...
This $195,036 two-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research analyzing paleomagnetic data from sediment and basalt core samples extracted during the International Ocean Discovery Program Expedition 391. A team of researchers led by The Leland Stanford Junior University will study samples cored from the Walvis Ridge in the South Atlantic Ocean to develop a paleolatitude record for Late Cretaceous and early Cenozoic volcanoes...
This three-year, $214,451 National Science Foundation project grant in the Geosciences program (CFDA 47.050) supports research to better constrain large-scale mantle convection through seismic imaging beneath hotspots. Key products include using converted and reflected seismic wave data from distant seismic stations to image the lithosphere-asthenosphere boundary and transition zone discontinuities beneath Hawaii, Yellowstone, and the equatorial Mid-Atlantic Ridge. These regions represent...
This $249,414 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support a collaborative research project to conduct a 3-D multichannel seismic survey at the 9°50'N segment of the East Pacific Rise. The project will repeat a similar survey conducted in 2008 to study how the magmatic and hydrothermal systems beneath the seafloor have evolved over the past decade. By processing and analyzing the seismic data using advanced techniques, the...
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to investigate mantle dynamics during the early stages of seafloor spreading in the Atlantic Ocean. The primary awardee, Louisiana State University, will conduct a novel 2D/3D seismic experiment to better understand how the central Atlantic Ocean first formed, with a focus on the evolution of oceanic crust and mantle during the initial ~50 million...
The National Science Foundation (NSF) awarded a $195,944 Project Grant under the Geosciences program (CFDA 47.050) to the University of Tennessee (UT) to conduct collaborative research on the evolution of the Tristan-Gough-Walvis Ridge hotspot system in the South Atlantic Ocean. The project will investigate the changing magmatic processes and interactions between the hotspot and overlying lithosphere during continental rifting and seafloor spreading through geochemical and geochronological analysis of volcanic core samples obtained during two International Ocean Discovery Program expeditions. Key research aims include documenting the evolution of the upper mantle contribution to hotspot volcanism and how the upper mantle changes as the South Atlantic expanded. The project will also support undergraduate and graduate research by students traditionally underrepresented in geosciences.
