B--X-Ray Fluorescence (XRF) analysis of split sediment cores

The U.S. Geological Survey intends to award a sole-source purchase order to Scripps Institution of Oceanography, University of California San Diego, for X-Ray Fluorescence (XRF) analysis of approximately 70 split sediment cores collected from lakes in Alaska, California, Oregon, and Washington. This action is being conducted under FAR Part 12 as a commercial item acquisition, with Scripps identified as the only source capable of delivering the required high-quality geochemical data essential for maintaining consistent, comparable results across ongoing USGS research. The analysis will quantify elemental abundances of light and medium atomic weight elements at a 1mm interval along each core, with results delivered as a digital spreadsheet or text file within 60 days of core receipt. The period of performance runs from September 1, 2026, through September 30, 2027, and all work will be performed at Scripps’ facility, where USGS will deliver the cores for analysis and the vendor will provide on-site technician support. Responses to this Notice of Intent must be submitted electronically to yangzhi_deng@ios.doi.gov no later than August 3, 2026, at 1500 PST, as no competitive solicitation will be issued, though all responsible parties may submit a quotation for consideration. The NAICS code is 541380, and while no contract value, pricing details, or formal evaluation factors are specified, the award will be based exclusively on the unique capability of Scripps to meet the data consistency requirements critical to USGS paleoseismology studies. No formal packaging, marking, invoicing, or security requirements are detailed beyond the stipulation that all deliverables must comply with USGS data release policies.
