1MHZ and 2MHZ Sideways Looking Profilers

1MHZ and 2MHZ Sideways Looking Profilers: The contractor will provide two 1MHz Horizontal Profilers and three 2MHz Horizontal Profilers.

The US Geological Survey (USGS) intends to negotiate on a sole source basis with NortekUSA, Boston, MA, for two NortekUSA 1MHz Aquadopp Horizontal Profilers, Part Number 901105, and three NortekUSA 2MHz Aquadopp Horizontal Profiles, Part Number 901104. This proposed action is for supplies which the Government intends to solicit and negotiate with only one source. NortekUSA is the only potential provider of these products. The USGS use Nortek USA profilers in various locations and consistency in data collection is paramount. NortekUSA profilers are the only low-noise 1 and 2 MHz sideways-looking acoustic-Doppler profilers on the market that include an internal compass and PUV wave-burst collection capability that is compatible with our existing acoustical suspended-sediment-measurement deployments in Grand Canyon, Dinosaur, Canyonlands, and Big Bend and data-processing methodologies. These units include two horizontal acoustic beams with 50 or more measurement cells, internal 0-10m pressure sensor, internal tilt sensor, internal compass, PUV Wave burst collection capability, and a noise filter to reduce night-time noise levels, not found on other comparable units. All responsible sources submitting an offer will be considered by the agency. Responses must include complete description of supplies to be provided, containing sufficient technical information, to allow agency analysis to establish bona fide capabilities. All proposals shall be sent to the Contract Specialist at sevans@usgs.gov.
