- Description
- ****NOAA's Acquisition & Grants Office, Western Acquisition Division-Boulder, intends to negotiate, on a sole source basis, under authority of FAR 13.106-1(b)(1) with Nortek USA Inc. ****The sole source determination is based on the National Oceanic and Atmospheric Administration's (NOAA) National Ocean Survey (NOS) Field Operations Division's need for Nortek's Signature1000 Acoustic Doppler Current Profiler (ADCP). Resolving accurate currents from small surface buoy platforms has been a major challenge for oceanographers and marine scientists. An ADCP uses its transducer geometry, the water's speed of sound, and the time between signal transmit and received echo to time-gate each depth bin's distance along each beam. The vertical distance to each bin is then the projection of all beams onto the instrument's vertical axis. For ADCPs mounted in a moving surface platform, one cannot assume the flow to be homogenous across each depth bin over each measurement interval due to orientations changes within the measurement interval. This causes inaccurate velocity data when the along-beam depth bin moves up and down, referred to as the "smearing effect." In addition, vertical shear can bias the resulting velocity because the depth bins move in and out of regions with variable velocity. This creates a measure of uncertainty in currents data provided to maritime navigation users, and increases the risk to mariners. Nortek has addressed this issue by developing the Signature series ADCP; no other manufacturer currently offers this capability. The Center for Operational Oceanographic Products and Services (CO-OPS) has successfully tested this sensor and confirmed this enhanced capability.
