This National Science Foundation Project Grant of $267,901 will fund research into the response of the upper tropical Pacific Ocean to greenhouse gas forcing from August 15, 2022 through July 31, 2025. The award was made under the Geosciences program (CFDA 47.050), which supports basic research in the atmospheric, earth, and ocean sciences. Specifically, the grant will support a collaborative research effort examining how the temperature, currents, and thermal structure of the upper tropical...
This $372,515 Project Grant awarded by the National Science Foundation (NSF) Geosciences program (CFDA 47.050) supports research to document variations in the influence of the Southern Hemisphere on the Western Pacific Warm Pool thermocline over the past 1.5 million years. The principal investigators at Columbia University will analyze geochemical data from deep-sea sediment cores to determine the timing and patterns of subsurface warming in the Western Pacific Warm Pool relative to surface...
This three-year, $830,233 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research examining the impact of greenhouse gas-induced global warming on tropical cyclones in the Pacific region. The Columbia University research team, in collaboration with sub-awardee The Trustees of Columbia University, will utilize flux adjustment techniques and high-resolution atmospheric modeling to simulate the response of key ocean temperature patterns to...
The National Science Foundation (NSF) awarded a $546,989 Project Grant to The Trustees of Columbia University in the City of New York, operating through its Sponsored Projects Administration Division, under the Geosciences (CFDA 47.050) program. The grant supports collaborative research to understand the non-linear and feedback mechanisms in the atmospheric circulation response to increased carbon dioxide (CO2) levels. The research aims to address the limited understanding of how warming-induced...
This three-year, $511,918 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research to develop a new framework for advancing climate model representations of cloud and convective processes. The grantee, Columbia University, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate data assimilation will...
This National Science Foundation (NSF) Geosciences program grant (CFDA 47.050) provides $202,000 to fund research to understand the differences between observed and simulated patterns of tropical Pacific sea surface temperature (SST) warming. The 2-year project, beginning January 1, 2024, involves comparisons between climate models and a simplified Zebiak-Cane atmosphere-ocean model to identify the physical mechanisms causing the contrasting SST trend patterns. The research has implications...
This $415,924 federal Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), will support collaborative research to investigate the large-scale dynamics of the tropical Indo-Pacific region during the Last Glacial Maximum. The project aims to reconstruct the tropical thermocline structure and wind patterns using ocean modeling and geochemical analysis of foraminifera sediment samples. This research will lead to a better understanding of how the...
The National Science Foundation (NSF) awarded a $588,786 project grant under the Geosciences Program (CFDA 47.050) to The Trustees of Columbia University in the City of New York (Columbia University) to develop replicated coral geochemical reconstructions to understand dynamics of the South Pacific Convergence Zone (SPCZ) in the context of climate change. The project aims to analyze temperature-sensitive elements preserved in coral cores from American Samoa, Fiji, and Tonga to reconstruct...
The University of Connecticut was awarded a $329,753 Project Grant from the National Science Foundation Division of Ocean Sciences on May 15, 2021 for research titled "Collaborative Research: Sensitivity of Walker Circulation to CO2 Forcing During the Late Pliocene as an Analogue for Future Climate Change." The research is being conducted under the NSF's Geosciences program (CFDA #47.050), which supports basic research in the atmospheric, earth, and ocean sciences to strengthen...
This $749,164 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research to reconstruct climate linkages across the tropical oceans over the last millennium. The University of California, Santa Barbara will collaborate with researchers to produce records of tropical sea surface temperature variability using geochemistry from long-lived corals in the Pacific, Atlantic, and Indian Oceans. Comparing multi-century coral data from these ocean basins...
