REQ 145027-25-0074 - Seaguard - SSD_For Posting1.pdf

This document is a Single Source Determination using Simplified Acquisition Procedures (SAP) for the Department of Commerce, NOAA Acquisition and Grants Office. The procurement is for two Aanderaa Seaguard II platforms to upgrade monitoring equipment for the NOAA EcoFOCI Mooring Array, with YSI, Inc. identified as the sole source vendor.

Market research confirmed that the Aanderaa SeaGuard II is the only instrument meeting the EcoCOCI program's technical requirements for sub-surface mooring applications, specifically requiring in-line mounting on a taut-line mooring, capable of collecting high-resolution, long-term single-point current measurements at a fixed depth. The instrument uniquely integrates multiple oceanographic sensors (current velocity, temperature, pressure, dissolved oxygen) in a compact, modular housing. The determination was made that no alternative platforms provide the necessary combination of inline mooring integration, single-point current velocity measurement, long-term autonomous deployment capacity, and integrated pressure, temperature, and oxygen measurements.
