Researchers will produce a paleolatitude timeline for comparison...
The National Science Foundation Division of Ocean Sciences awarded a $405,037 Project Grant to the South Dakota School of Mines and Technology under the Geosciences program (CFDA 47.050) for research from February 1, 2022 to January 31, 2025. The award will support collaborative research to better understand how the depth of magmatic processes in the mid-ocean ridge system varies based on tectonic setting. Researchers will analyze melt inclusions and crystals in ocean floor basalts from a...
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 $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...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a 3-year, $325,841 Project Grant to the University of Wyoming under the Geosciences program (CFDA 47.050) to conduct collaborative research on understanding the processes and timescales of basalt petrogenesis and oceanic crustal construction at slow-spreading mid-ocean ridges. The research will measure the chemical characteristics of volcanic rock produced along the Mid-Atlantic Ridge to understand mantle melting and...
The National Science Foundation (NSF) awarded a $196,306 Project Grant under the Geosciences Program (CFDA 47.050) to the University of Wisconsin - Madison to conduct research on how the Mid-Atlantic Ridge impacts the ocean and climate. The 5-year project, beginning on May 1, 2024, will explore how the removal of this key topographic feature affects the North Atlantic Ocean's circulation and climate patterns globally. The study aims to inform climate model development and reduce biases, as...
The National Science Foundation (NSF) awarded a $236,732 Project Grant under the Geosciences Program (CFDA 47.050) to Louisiana State University (LSU) to conduct a seismic experiment to investigate mantle dynamics during the early stages of seafloor spreading in the Atlantic Ocean. The project aims to characterize the evolution of oceanic crust and mantle as the Atlantic Ocean formed, shedding light on the anomalous geology and mantle conditions present during the initial ~50 million years of...
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 South Atlantic over time. The research team will analyze core samples obtained from six drill sites along the Tristan-Gough-Walvis Ridge to conduct geochemical and geochronological studies. This research aligns with the Geosciences program's goal of expanding fundamental knowledge and understanding of the integrated Earth system through basic research in the atmospheric, earth, and ocean sciences. The award period is from July 15, 2023 to June 30, 2025.
