The Department of the Interior, through the United States Geological Survey (USGS), is conducting market research to identify qualified vendors for specialized laboratory services in tree-ring based paleoseismology. The procurement aims to secure dendrochronological and isotope geochemical laboratory services to support research on prehistoric earthquakes along the Cascadia Subduction Zone, including tasks such as crossdating, high-precision sample preparation, radiocarbon dating, and stable isotope analysis. These services are crucial for developing regional tree-ring chronologies that enhance understanding of seismic activity in the region. Interested vendors must demonstrate relevant experience and in-house capabilities, and are encouraged to submit their capability statements via email to Joel Berberena at jberberena@usgs.gov, adhering to the specified submission guidelines. This Request for Information (RFI) does not guarantee a contract but will inform the government's acquisition strategy.
