This is a Request For Information - This synopsis is for information and planning purposes only and is not to be construed as a commitment by the Government. No contract will be awarded as a result of this Sources Sought announcement. The United States Geological Survey, Office of Acquisition and Grants is soliciting information from qualified sources; the results of this announcement will be evaluated to determine if there are businesses capable of performing the proposed work.
The US Geological Survey, Office of Acquisition and Grants seeks responses from vendors that possess the capability to supply a new Multibeam Echosounder (MBES) suitable for use in shallow water. The following specifications pertain to Grand Canyon Monitoring Research Center's requirement for a portable MBES that can be deployed from a small vessel in shallow water and measures at high resolution over a wide swath width such that it is possible to survey up to the edge of water.
-        Size: To be deployed from a small vessel, the inertial navigation system and all transducer elements and sound-speed probe must be integrated in a single "wet end" configuration that, with included calibrated mounting bracket, must not measure more than 0.45 meters in any dimension and must weigh less than 20 lbs. In addition, the ¿top side¿ processor must fit in available space on boat: 12" x 9" x 5" or smaller.
-        Hydrodynamic: The system must include a hydrodynamic fairing integrated in the calibrated mounting bracket. This is required because the system will be used in rivers at speeds of up to 4 to 7 knots and pole-mounted on a 1.5" pipe.
-        Resolution: The system must be capable of operating at up to 1024 beams and frequency agile in the 200 to 700 khz range such that resolution of up to 0.3 degree across-track and 0.5 degree along track is possible at the highest frequency. This resolution is required for research purposes and to match the standards of equipment currently in use.
-        Swath width: The system must be capable of collecting bathymetric data across a swath at minimum 200° wide at speeds of 4 - 7 knots and it must be possible to rotate a smaller swath within the full 200 degree range without manually tilting the sonar head. These capabilities are required to allow mapping up to the water surface.
-        Inertial navigation system (INS): The system must include a tightly integrated high-resolution GNSS/INS that has 0.01° roll and pitch accuracy and 0.02° heading accuracy. These performance specifications are required because the system will be operated over a wide swath in highly dynamic river environments.
-        Data products: The system must provide real-time output of bottom detection data (utilizing modern approach that incorporates amplitude, phase, and blend), multibeam-sidescan, and beamformed intensity time series (snippets and watercolum). These data outputs are required for scientific purposes and to match the standards of equipment currently in use.

Interested parties should submit a Capability Statement to the Contracting Officer, Charlan Fejarang at cjfejarang@usgs.gov by the due date, Tuesday, August 15, 2023.
