66 -- Salinity Sensor for the Tropical Atmosphere Ocean (TAO) Array

The National Data Buoy Center plans to enter negotiations exclusively with Sea-Bird Electronics, Inc. for the procurement of 54 MicroCAT Conductivity and Temperature Recorders, model SBE-37 SMP. These instruments are designed to measure the salinity of seawater by accurately detecting conductivity and temperature, averaging the collected data over time, and outputting the results. The sensors must meet stringent performance standards, including a conductivity range of 0 to 7 S/m with resolution and stability specifications, as well as a temperature range from -5 to 35 degrees Celsius with precise accuracy and stability measurements. Additionally, the sensors are required to feature an external power input capability to ensure reliable field operation. This contract, identified under solicitation number Reference-Number-NWWG9500-6-26980, is managed by the Department of Commerce’s National Oceanic and Atmospheric Administration and is related to the acquisition of salinity sensors for the Tropical Atmosphere Ocean (TAO) Array. The contract supports efforts tied to NAICS code 334519, which covers manufacturing of instruments and related products. The office handling this acquisition is located in Kansas City, Missouri, emphasizing the federal oversight and logistical posture for fulfilling these specialized technology needs.
