66 -- ACOUSTIC DOPPLER CURRENT PROFILER AND DISCHARGE MEASUREMENT SOFTWARE POC Gwendolyn Woods 228/688/2109 WEB: Specifications for acoustic doppler measurement system, http://wwwhif.er.usgs.gov/public/acoustic.html. E-MAIL: Contracting Officer, gawoods@usgs.gov. This is not a solicitation notice. The U S Geological Survey has prepared for industry comment preliminary specifications and related information for an acoustic discharge measurement system. This system is composed of an acoustic doppler profiler, a personal computer (laptop or desktop) and a discharge program running the computer. The profiler must operate under the supervisory control of the user acting through the computer program. When commanded by the user, the profiler must perform the measurements which are fundamental to a discharge calculation and periodically transfer the results in the form of data ensembles through its data interface to the computer program. The profiler must continue this operation until commanded by the user to stop. The data ensembles are processed by the computer program as required to determine the discharge and compile a final record. The program (software) must integrate the operations of the other system components into a fully orchestrated discharge measurement procedure. It must provide the interface through which the user can prepare the system for measurement, start and stop the measurement procedure, monitor and control measurement operations, and support the playback and post processing of measurement records. During a measurement it must acquire data from the system components, process the data as needed to determine the discharge, and create and store the measurement records. The Request for Comment (RFC) document will be available on or about April 20, 1998. No formal solicitation or contract will result from this synopsis. Any subsequent formal solicitation will be synopsized prior to its release. Comments received as a result of this review may be incorporated into the final specifications and related information. The RFC may be obtained on the WEB or upon written request. No telephone request for the RFC document will be accepted. Any comments in response to this RFC must be received within 30 days after issuance of the RFC document. The Government does notintend to pay for the information solicited except as provided in subsection 31.205-18, Independent Research and Development and Bid Proposal Costs, of the Federal Acquisition Regulation. Any questions should be addressed in writing to Gwen Woods at the address specified in this announcement or E-mail. (0100)
