Opportunity Summary:
The Bureau of Land Management (BLM) funding opportunity titled "Paleoprecipitation Climate Model" (Funding Opportunity Number L11AS00169) supports a research project aimed at reconstructing a long-term rainfall history for Idaho's Salmon River basin. The core goal is to document approximately 13,000 years of precipitation change by analyzing oxygen isotope ratios preserved in the carbonate shells of freshwater river mussels and land snails recovered from archaeological sites along the lower Salmon River. Because these mollusks incorporate oxygen from the water they absorb as they build their shells, the shell chemistry can serve as a basin-wide signal of past water conditions. In turn, changes in oxygen isotope ratios (specifically oxygen-18) can be used as a proxy for shifts in precipitation patterns through time.
The project approach centers on building a high-resolution paleoclimate record by sampling shell material at close intervals along each mollusk's growth axis. The announcement specifies taking subsamples at 10 mm increments, then submitting those subsamples for stable isotope analysis. These results will be compared with modern isotope signatures from both freshwater and terrestrial mollusks to help anchor interpretations and translate shell isotope patterns into meaningful, subdecadal-scale reconstructions of past precipitation. To ensure the reconstructed climate timeline is reliable, the project will establish age control by directly radiocarbon dating each sampled shell, tying the isotope measurements to specific points in time rather than relying solely on site context or indirect dating.
Once the isotope and dating data are assembled, statistical analyses will be used to identify broader patterns, trends, and variability in the paleoprecipitation record. The intended output is a model or reconstruction that characterizes how rainfall in the Salmon River basin has changed across millennia, offering insight into long-term hydroclimate dynamics that can inform natural resource understanding and cultural resource contexts in the region.
From an administrative standpoint, this is a discretionary grant using a cooperative agreement as the funding instrument, reflecting that BLM may expect active collaboration or involvement consistent with that mechanism. The activity category is Natural Resources, and it is associated with CFDA 15.224 (Cultural Resource Management), which aligns with the use of archaeological shell materials and the intersection of environmental reconstruction with cultural resource datasets. The opportunity anticipated a single award, with an estimated total funding amount of $87,000 and an award ceiling of $87,000 (award floor listed as $1). No cost sharing or matching requirement is indicated. Eligibility is listed as unrestricted, though the notice notes the project meets the criteria for CESU arrangements, meaning it fits within the framework of the Cooperative Ecosystem Studies Units partnership model, which can shape how the award is implemented and partnered.
Key dates in the original posting show it was posted and created on July 15, 2011, with an original and current closing date of August 7, 2011, and an archive date of July 15, 2012. Application instructions and forms were provided through the announcement's "APPLICATIONS" tab. The listed grants management contact for access issues was Melinda D. Ritacco, Grants Management Officer, reachable by phone at 208-373-4018 or by email at mritacco@blm.gov.

4) What geographic area does the project focus on?
The focus area is Idaho's Salmon River basin, specifically referencing archaeological sites along the lower Salmon River.
5) What kind of scientific record is the project trying to produce?
The project is intended to produce a high-resolution paleoclimate (paleoprecipitation) record that characterizes how rainfall has changed across millennia, at subdecadal-scale resolution where possible.
6) What materials will be analyzed to reconstruct past precipitation?
The project analyzes carbonate shells from freshwater river mussels and land snails recovered from archaeological sites along the lower Salmon River.
7) Why are mollusk shells useful for reconstructing past rainfall?
These mollusks incorporate oxygen from the water they absorb as they build their shells. Because of that, the shell chemistry can preserve a basin-wide signal of past water conditions.
8) What specific chemical indicator will be measured in the shells?
The project uses oxygen isotope ratios preserved in the shells, with emphasis on oxygen-18 (O-18) as a proxy indicator for shifts in precipitation patterns over time.
9) How will the shell samples be collected for analysis?
The approach involves sampling shell material at close intervals along each mollusk's growth axis. The announcement specifies taking subsamples at 10 mm increments.
10) What type of lab analysis will be performed on the subsamples?
The subsamples will be submitted for stable isotope analysis to measure the oxygen isotope ratios used in the precipitation reconstruction.
11) How will the project connect ancient shell isotope data to present-day conditions?
The results will be compared with modern isotope signatures from both freshwater and terrestrial mollusks. This comparison is intended to help anchor interpretations and translate shell isotope patterns into meaningful reconstructions of past precipitation.
12) How will the project establish the timing (age control) of the reconstructed record?
Age control will be established by directly radiocarbon dating each sampled shell. This ties the isotope measurements to specific points in time rather than relying only on archaeological site context or indirect dating.
13) What happens after isotope measurements and radiocarbon dates are obtained?
Once the isotope and dating data are assembled, statistical analyses will be used to identify broader patterns, trends, and variability in the paleoprecipitation record.
