A prior $705,315 sole-source purchase order awarded June 8, 2023 (with a September 30, 2024 completion date) provided real-time continuous inductive hypoxia monitoring system equipment for NOAA's National Marine Fisheries Service Office of Habitat Conservation Chesapeake Bay Office, justified on grounds of compatibility and system integration requirements with existing Soundnine infrastructure already deployed in the Chesapeake Bay Program.
