STABLE ISOTOPE SAMPLE ANALYSIS

The U.S. Geological Survey Florence Bascom Geoscience Center is soliciting quotations for the stable isotope analysis of carbonate microfossils, specifically 12C/13C and 18O/16O isotope ratios on benthic foraminifera and ostracodes from marine sediment samples. This work supports the Paleo-perspectives on hazards and ecosystem change project to reconstruct global ice volume, ocean temperature, circulation, and salinity. The contract involves up to 2,000 measurements to be completed by September 30, 2027, with a general period of performance of one year after receipt of award and no option periods. All data must be reported relative to Carrara Marble standards, and the contractor must meet specific analytical precision requirements for carbonate samples in the 5-250 microgram size range. This is a full and open competitive solicitation under NAICS code 541380, with a size standard of 19 million dollars. Award will be made to the responsible offeror whose proposal is most advantageous to the government, based on an evaluation of technical capabilities, compliance with salient characteristics, and price. Offerors must be registered in the System for Award Management and provide a detailed capabilities statement addressing the statement of work. Deliverables include corrected isotope values, analytical uncertainties, and detailed methodology, with all sample analysis required to be completed within six months of receipt. Invoicing must be processed through the Invoice Processing Platform, and the work will be performed at an external laboratory.
