Popis

FUNCTION: Facilitates routine maintenance for NRL seagoing measurement systems: ocean current (Barny, SEPTR); ocean temperature and salinity (ScanFish); ocean turbulence (VMP); airborne salinity (STARR); and air-sea interaction (WGA/SSS). This facility is equipped with high-precision machinery, calibration chambers, and electronic equipment to adjust, repair, and assemble mechanical and electronic components of the systems. DESCRIPTION: To achieve a consistently high level of data quality from field experiments, seagoing measurement systems are required to endure harsh marine environments and to operate with their designed measurement capability throughout the deployments. This requires continuous maintenance efforts including calibrations, adjustments, tunings, modifications, and storage for electronic and mechanical components of various seagoing systems during the pre- and post-deployment stages. These functions are conducted in this facility, which consists of an electronic assembly and readiness lab, machine and welding lab, sensor calibration lab, 1500 ft 2 experiment staging area(high-bay)and temperature-controlled storage center. The facility is essential for maintaining the readiness and integrity of the NRL measurement systems. INSTRUMENTATION: • Bridgeport vertical milling machine; Tradesman bandsaw • MIG-TIG welding machine (Shopmaster 300) • Nardini Mascote MS-1440 precision lathe • 2-ton Presto PSTA2107 pallet stacker • 2-ton overhead monorail crane.
