Single Source Determination 24-073 signed FD _Redacted.pdf

This document announces a sole source contract opportunity. The National Oceanic and Atmospheric Administration intends to negotiate with In Situ Marine Optics to procure two self-contained, ship-mounted radiometer systems called Dynamic Above-water Radiance (L) and Irradiance (E) Collectors. These instruments are designed to autonomously collect hyperspectral reflectance data from 350 to 900 nm to facilitate linking measurements from NOAA surveys to satellite ocean color data. The technical specifications require simultaneous collection of downwelling irradiance, sky radiance, and ocean radiance at 10 nm spectral resolution and 4 nm sampling. Additional requirements include a passive gimbal mount, auto-azimuth control to mitigate sun glint, an internal compass, integrated GPS, and a compact sensor form. The data will provide a sustained dataset on lower trophic levels to consider ecosystem impacts on fisheries and environmental change.
