This $267,007 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant will fund a collaborative research project at Alabama A&M University to reconstruct a 250-300 year record of rainfall extremes and Amazon River water level fluctuations in the Eastern Amazon region. The project aims to use tree-ring data from Cedrela odorata and historical records to determine if recent flood and drought events are within the natural range of climate variability or attributable to...
This Project Grant award from the National Science Foundation's Biological Sciences program (CFDA 47.074) will support research at the University of Arizona to investigate the potential impacts of drought and forest degradation on the Amazon rainforest's water cycling and susceptibility to tipping points. The $103,764 award, effective from February 2024 to January 2025, will fund field observations, data collection, and analysis to test three key hypotheses related to the Amazon's drought...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to better interpret past climate and plan for future changes. The total funding amount is $324,677, with an award date of July 1, 2024 and an ultimate completion date of June 30, 2027. The key products and services to be delivered under this grant include: Using dendrometers (instruments that record tree growth in real-time) to...
This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) will fund a collaborative research effort to investigate subsurface water storage and seasonal dynamics in the Amazon rainforest and a savanna site in Brazil. The $363,098 award supports geophysical surveys, data analysis, and integrative modeling over a 3-year period from Aug 1, 2023 to Jul 31, 2026. The research, conducted in partnership with Brazilian...
This $211,743 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to aid interpretations of past climate and plan for future changes. The primary objectives are to: Use dendrometers to measure how tree growth responds to changes in precipitation frequency, intensity, and timing at sites in the AmeriFlux network. Reconstruct wet extremes of precipitation from previously collected tree-ring...
This $861,035 Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports research into how mature trees in the Amazon rainforest are adapting to rising temperatures. Researchers at the University of Miami will conduct field studies around Peru's "Boiling River", a unique geothermal area that mimics the predicted future temperature conditions for much of the Amazon. The key objectives are to 1) map the environmental conditions in...
The National Science Foundation (NSF) awarded a $192,386 Project Grant through its Geosciences program (CFDA 47.050) to the University of Arizona for a 3-year collaborative research project to reconstruct tropical rainfall patterns over the last 200 years. The project aims to use stable oxygen isotopes measured in tree ring cellulose from sites across Central and South America to study variations in the position and width of the Intertropical Convergence Zone and understand how these changes...
This $101,087 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to create a seasonal-resolution paleo-streamflow reconstruction for Southeast Asia. The key products and services to be delivered include: Synthesizing existing tree-ring proxy data (ring width, stable oxygen isotope ratios, blue light intensity, and Palmer Drought Severity Index) to develop the paleo-streamflow reconstruction. Comparing the...
This $146,700 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports a collaborative research project to synthesize existing tree-ring proxy data in Southeast Asia and compare it to paleo-streamflow estimates generated by a hydrological model. The goal is to create a seasonal-resolution paleo-streamflow reconstruction for the region and illuminate the mechanisms driving observed streamflow dynamics. The project includes support for two early...
This Project Grant award from the National Science Foundation's Biological Sciences program provides $2,453,417 to Yale University to study how forest fragmentation and climate change impacts the Amazon rainforest ecosystem. The key products and services to be delivered include: Field-based measurements of forest dynamics, animal exclusion experiments, and remote sensing mapping to examine how changes in tree species and animal populations affect the resilience of Amazon forest edges to...

This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $276,385 to the University of Arkansas will support a collaborative research effort to reconstruct and analyze precipitation and streamflow in the Amazon River Basin over the past 250-300 years. The key products and services to be delivered include:

  1. Creating a long-term record of rainfall extremes in the eastern Amazon using tree-ring data from the Cedrela odorata species, which demonstrates reliable annual growth rings. This will help determine if recent flood and drought events are within the natural range of climate variability or attributable to factors like global warming and deforestation.

  2. Constraining historical high and low river levels in the 19th century Amazon using the tree-ring data and historical records from the Brazilian Digital Library. This information will be used to model the physical mechanisms behind drought and flood extremes in the region, including the potential impact of deforestation on river levels.

  3. Investigating the paleoclimate potential of another tree species, Denezia excelsa, and developing an outreach and education website on the forests and climate of the Amazon. The project will also lead workshops on tree-ring dating methods.

The award period runs from September 1, 2024 to August 31, 2027. No subawards are planned under this grant.
