T -- UPPER COOK INLET AND NORTHERN ALASKA AEROMAGENTIC DATA SOL 00CRQQ0285 DUE 090400 POC Robert C. Valdez, Contracting Officer (303) 236-5900 ext 424 Concerns having the ability to require detailed aeromagnetic data in study areas in northern and southern Alaska as described herein are requested to give written notification (including the telephone number for a point of contact) to the procuring office above within forty-five (45) calendar days from the date of this synopsis. The following Salient Characteristics are considered essential to this requirement. The U.S. Geological Survey, Geologic Division requires detailed aeromagnetic data in study areas in northern and southern Alaska. In northern Alaska, the Energy Resources program requires detailed magnetic data to evaluate geological structures for oil and gas resource assessment. In southern Alaska, the Energy, Mineral, Hazards, and Mapping programs require aeromagnetic data for geologic mapping beneath covered areas, energy and mineral resource assessments, and earthquake risk assessment. Data Specifications: The data shall have a minimum flightline spacing of 0.5 mi (800 m) and be flown as low as practicable given the proximity of magnetic source rocks to the surface. Typically this means flight heights of 250 to 1000 feet above terrain. Data Location: Data placement is designed to interface with previously purchased data segments in these areas. Data figures are available upon request from the Contracting Officer. Deliverable Items and Schedule: The processed aeromagnetic survey and documentation shall be provided on CDROM within thirty (30) days of the contract award. Limited Publication Rights: Derivative geologic map interpretations made by the USGS based on the contractor's aeromagnetic data may be published at a scale of 1:250,000 or smaller. Profile data for north-south and east-west interpreted geologic cross sections of magnetic models may be published by the USGS at a scale of 1:250,000 or smaller. A summary of color maps of the entire area for intermediate and long wave-lengths (greater than 6 km) may be published by the USGS at a scale of 1:500,000 or smaller. Higher resolution maps of limited area (less than 10 km in width or length, without coordinates, and at a scale of 1:100,000 or smaller) may be published by the USGS to illustrate the type of magnetic signatures that are associated with different geologic features. Any USGS published illustrations of the aeromagnetic data itself will be limited to page size or smaller (less than 7 x 9 inches). Published illustrations including any of the contractor's data or geologic interpretation based on the aeromagnetic survey will acknowledge the name of the contractor, but the USGS can not endorse a contractor of use either logos or trademarks. USGS illustrations for reports that contain the contractor's data or interpretations derived primarily from the aeromagentic survey shall be provided to the contractor after internal USGS review and before publication or submission to an outside journal to allow the contractor to comment on the interpretation as to assure the illustration conform to these guidelines. The final geologic interpretation will be the responsibility of the USGS. Any illustration by the USGS at a larger scale or higher resolution than specified herein shall be approved in advance by the contractor. Upon request there are drawings available through the Contracting Officer at (303) 236-5900 ext 424. Based on information available at this time, and in accordance with 41 U.S.C. 253 (1), implemented by FAR 6.302-1, the Government considers the item specified as a sole source from Fugro Airborne Surveys, 2060 Walkley Road, Ottowa, Ontario, Canada and proposes to negotiate a contract with that firm on that basis. However, should additional sources be identified, they will be considered. Firms who feel that they can furnish the required item or its functional equivalent (based upon the criteria specified herein) are invited to submit in writing an affirmative response to this announcement. An affirmative response would include literature, brochures and such other materials which correspond to the required items stated herein. This information will be evaluated and used to determine if competitive opportunities exist. This notice may represent the Governments only official notice of this procurement. See Notes 22.
