F -- TURBULENT SHEAR FLOW STUDY SOL NRMGL000801129 POC Doris Turner, Purchasing Agent, 303-497-3872; FAX: 303- 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Oceanic and Atmospheric Administration (NOAA), Environmental Technology Labs (ETL) requires the use of a unique, large-scale laboratory facility for studying processes in the upper ocean. This includes a large thermostratified tank (20m x 4m x 2m) with a controlled thermocline-type stratification which models the upper ocean structure at about 1: 100 of spatial scale and about 1:10 of velocity scales and the closed wind-wave tank for modeling processes involving the wind action on the surface. The tanks are fully equipped with generators of surface and internal waves, a flow inductor, wind channel, etc., and a measuring complex with the computer-based data collection and processing. The purpose of the work, which involves both tanks, is to study the interactions between internal gravity waves (IW), turbulent currents, and surface waves, evaluate the possibility of generation, amplification and modulation of the wave disturbances and describe the main mechanisms of the phenomena observed. It is the intent of the Government to negotiate a sole source contract under the authority of 41 U.S.C. 253(c)(1) with The Institute of Applied Physics at Nizhny Novgorod (Russia) as this source is considered to be the only responsible source and no other source can satisfy agency requirements. This announcement is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00). Agency level protest procedures are at http://www.doc.gov/oam/conops/#REFERENCE.
