- Description
- This is a notice of intent to solicit from a single source. The U.S. Geological Survey (USGS), intends to award a purchase order to University of California (UC), Irvine, Irvine, CA for radiocarbon analyses as described in the attached Statement of Work. Award will be made in accordance with Federal Acquisition Regulation (FAR) 13.106-1(b) and the procedures at FAR Part 12 entitled, Acquisition of Commercial Items and FAR Part 13 entitled, Simplified Acquisition Procedures. UC Irvine is, to the USGS' knowledge, the only source who can provide continuing services in support of the Lacustrine Paleoseismology task and ensure date uniformity. The purpose of this notice is to satisfy the requirements of FAR Subpart 5.2. This notice of intent is not a request for competitive quotes. However, all responsible parties may submit a quotation by the closing date of this announcement which shall be considered by the agency. No solicitation will be issued. A determination not to compete this action based upon responses received is in the sole discretion of the Government. The NAICS code for this action is 541380. Testing Laboratories. Responses or inquiries shall only be accepted through electronic mail addressed to dallan-loucks@usgs.gov and must be uploaded and received in their entirety no later than 08/04/2022 1500 ED. Responses submitted by hardcopy shall not be accepted or considered. STATEMENT OF WORK I. GENERAL INFORMATION A. Introduction: The USGS Lacustrine, Coastal and Marine Paleoseismology Project in the Pacific Coastal and Marine Science Center (PCMSC) requests radiocarbon (14C) analysis of organic samples and foraminifera samples from sediment cores by the W.M. Keck Carbon Cycle Accelerator Mass Spectrometry facility at the University of California-Irvine (WMKAMS-UCI). Radiocarbon (14C) dating of fossil material is a key aspect of geoscience, particularly during the Holocene Epoch (e.g., the last 11,500 years). This process uses the natural radioactive decay of 14C to 12C in preserved organic matter as a geochronometer for determining the age of deposition of geological units. The analysis of 14C decay is the basis for constructing an age scale for a geological record, and thus is one of the most important analyses performed in marine sedimentary stratigraphy. B. Background: Samples from the sediment samples collected at key sites along the U.S. West Coast and Alaska a used to refine the earthquake recurrence along active plate boundaries and fault systems. These data are a critical component of USGS National Seismic Hazard Maps, which provide hazard and risk assessment to millions of people in population centers in the Pacific Northwest. This task is fully within the purview of the USGS mission for the Coastal and Marine Hazards and Resources Program, the Earthquake Hazards Program, and is a critical component of USGS Marine Geohazards research. C. Scope: The scope of the requested work will be for WMKAMS-UCI to provide 14C analysis of two hundred and fifty-two (252) samples (mostly plant fragments, some foraminifera) from sediments acquired in cores and other paleoseismic sites. These results will be used to assess and refine the ages of earthquake deposits, both subaqueous and subaerial. Improving age constraints and correlation of event deposits along active continental margins are critical to developing a more robust earthquake history and predicting future earthquakes as well as potentially tsunamigenic events. II. WORK REQUIREMENTS A. Technical Requirements. The following technical requirements apply to this SOW for WMKAMS-UCI 14C analysis: 1. Submitted samples will be plant fragments, charcoal, and carbonate-rich foraminifera, on the order of <1 to 10 mg sizes. 2. Analyses shall be performed using an accelerator mass spectrometer. 3. Required measurements will include D14C, fraction modern, and an uncalibrated 14C age. Errors will be assessed at the 1-sigma level for each measurement. 4. Analyses should also account for matrix-specific background corrections and �13C normalizations, as deemed appropriate. 5. All measurements will be reported according to the international radiocarbon standard, as set forth in Stuvier & Polach (Radiocarbon 29, 1977, 355-363). Criteria for acceptance will include a detailed table of results as indicated in #3 above (including reporting of analytical errors), as well as a description of the methods used. B. Deliverables. Deliverables for this work will include: 1. An electronic report detailing the D14C, fraction modern, and an uncalibrated 14C age for each sample, as well as an assessment of the 1-sigma error. 2. An electronic report detailing methods of analysis. 3. Expected delivery date for the final set of analyses is 09/30/2025 to Technical Liaison. III. SUPPORTING INFORMATION A. Place of Performance: Contractor's Facility B. Estimated Period of Performance: 10/01/2022 - 09/30/2025
