The NOAA National Ocean Service requires a highly portable, turnkey underway profiling system for use on small survey craft and vessels of opportunity, primarily to support hydrographic workforce training. The system must include a winch, davit, control box, sensors, and software, and be deployable by a small team with common hand tools. Delivery is required by December 31, 2026, with earlier delivery preferred, to Durham, New Hampshire. No budget amount is specified in the description. This is a sources sought notice for market research, not a solicitation for proposals.
