E-MAIL: Deborah A. Bittner, Deborah.A.Bittner.1@gsfc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued unless necessary for clarification. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Research vessel to take surface salinity measurements across the Gulf Stream as validation for salinity measurements taken remotely from the NASA P-3 Aircraft. It has been demonstrated that, in principle, sea surface salinity can be measured from space because of the dependence of emissivity on surface salinity at low microwave frequencies (.5 to 2 Gz). The measurement has been taken successfully in the coastal zone where salinity variability is high (over 10 psu), but the measuring system was not optimized for the open ocean where the signal is only about 2 psu. Two radiometers will be used in the P-3; a quadrant engineering real apature scanning low frequency microwave radiometer (SLMFR) and an electronically sanned thinned array radiometer (ESTAR). The measurements from the two radiometers will be compared with each other and with the in situ measurements from the ship. This cruise will take place approximately the first two weeks of October, 1998. Cruising range requirements are: 1) ship must be capable of operating at cruising speed (~10 knots) for up to seven days, and 2) ship must be able to operate over 300 nautical miles from the coast. A research vessel is required since 1) they are already equipped with instruments to measure ocean temperature and salinity and meteorological parameters of relevance to the radiometer measurement, 2) they already have operation data acquisition system, and 3) they have the technicians aboard who are familiar with this equipment. The SIC code and the small business size standard for this procurement are 7375. The quoter shall state in their quotation their size status for this procurement. All qualified responsible business sources may submit a quotation which shall be considered by the agency. Delivery of information retrieved shall be made within 60 days of completion of the cruise. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9. Quotations for the items(s) described above may be mailed or faxed to the identified point of contact by the date/time specified and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative.
