In - indiana ES - indiana BAT stable isotope analy

The Fish and Wildlife Service seeks stable hydrogen isotope analysis of Indiana bat hair samples for geographic assignment and migration pattern research, with quotes due July 29, 2026. The procurement is a Women-Owned Small Business set-aside.

The contract is a firm-fixed-price order with a base performance period from October 1, 2026, through December 31, 2027. The contractor will analyze approximately 200 Indiana bat hair samples collected from roughly 10 hibernacula across the species' range, with samples potentially collected through March 2027. Work includes sample preparation, d2H isotope analysis using high-temperature pyrolysis and IRMS, spatial assignment modeling with probability surface generation, and comprehensive technical reporting. Deliverables comprise a final d2H dataset in CSV/Excel format with uncertainties and metadata, full documentation of analytical workflows, geospatial assignment probability surfaces in GIS-compatible formats, a final technical report in peer-reviewed journal manuscript style, and return or disposal of remaining samples as directed.

The contractor must operate an accredited stable isotope laboratory with documented experience conducting d2H analysis of keratin using high-temperature pyrolysis and IRMS, applying comparative equilibration methods normalized to VSMOW-SLAP standards, and performing isotope-based geographic assignment with recognized spatial assignment software. All data, metadata, code, and scripts must be provided in open, non-proprietary formats and archived for a minimum of five years. Quotes must be submitted as a single PDF to dana_arnold@ios.doi.gov by 3:00 PM Central Time on July 29. The Government will evaluate offers using a trade-off analysis based on technical approach, technical experience, past performance, and price. NAICS code is 541380, Testing Laboratories and Services; PSC is B516, Special Studies/Analysis – Animal/Fisheries.
