The document outlines a Limited Sources Justification for the procurement of twenty-four HTI-92-WB hydrophones from High Tech Inc. by the National Marine Fisheries Service under the Multiple Award Schedule Program. These hydrophones are essential for collecting passive acoustic data on offshore cryptic marine mammals, ensuring compatibility with existing acoustic recording devices. The anticipated delivery is set for April/May 2025. The justification for limiting the procurement to High Tech Inc. is based on the unique capabilities of their hydrophones, which have the required sensitivity to accurately record the targeted species. This exclusivity fosters consistency in data collection across different scientific institutions that have utilized these hydrophones since 2016. Market research indicates that sensitivity levels are critical for effective detection, and High Tech Inc. is the only supplier that meets these highly specialized requirements. The document effectively emphasizes the necessity of these particular hydrophones for sustainable marine mammal research and inter-center collaboration.
The NOAA National Marine Fisheries Service (NMFS) intends to procure 24 HTI-92-WB hydrophones for underwater acoustic recording as part of its initiative to enhance population estimates of cryptic marine species. These hydrophones will connect to SoundTrap ST620 recorders, enabling accurate data collection to monitor marine animal vocalizations and assess ocean noise. The devices must possess specific features, including a sensitivity of -155 dB/1v/uPa, an adjustable sample rate up to 192 kHz, and low self-noise. Delivery is required within 90 days of the contract award, which includes a base year with four option years, totaling up to five years of performance. The acquisition supports the Passive Acoustic Strategic Initiative aimed at improving understanding of marine species distribution and the acoustic environment, critical for informed stock assessments.
