NOAA intends to award a sole-source purchase order to Soundnine Inc. for maintenance, calibration, and parts for a proprietary 10-buoy hypoxia monitoring system in the Chesapeake Bay. The justification is that Soundnine is the original manufacturer and the only vendor capable of servicing this closed-loop system, as they do not authorize any third-party service providers. The period of performance is from September 26, 2026, through September 25, 2027. While this is a presolicitation notice and not a request for competitive proposals, firms believing they can meet the requirements may submit documentation to the point of contact.
