UNSPSC 81151911: Marine geophysical survey

Marine Geophysical Survey is a collective term for non-invasive, remote-sensing techniques which can be used to investigate the physical characteristics of the Earth.

UNSPSC 81151911 Marine geophysical survey is a Commodity code whose scope bears little alignment with recent state and local opportunities tagged under it. The code nominally describes marine geophysical surveying work, yet the five recent solicitations posted between February and July 2026 address groundwater monitoring, hydrogeological consulting, open educational resources technical assistance, park irrigation design, and roofing assessment—none of which constitute marine geophysical surveys. The Texas Water Development Board's brackish groundwater production zone analysis (58027RFP0003, due August 6, 2026) is the closest substantive match, involving geophysical log documentation and GIS subsurface mapping across fourteen Central Texas counties, and requires personnel with ten years of hydrogeology experience and professional geoscientist licensure. Sarasota County (Carlton Water Quality Monitoring, RPS due April 9, 2026) and Volusia County (Professional Hydrogeological & Well Services, RSQ due April 9, 2026) both solicited groundwater and well-related consulting in Florida. The Texas Higher Education Coordinating Board posted a technical assistance RFP for open educational resources grant support (7816CB14, due May 21, 2026), and the City of DeBary issued a park irrigation improvements bid (0315, due April 10, 2015—a historical posting). These opportunities suggest the code may be misapplied in state and local procurement systems, capturing hydrogeological and water-resource consulting work that belongs under different UNSPSC families rather than marine survey.

The issuing bodies span state water agencies (Texas Water Development Board), state education authorities (Texas Higher Education Coordinating Board), county water and utilities divisions (Sarasota and Volusia Counties in Florida), municipal parks departments (City of DeBary), and county facilities management (Broward County). Recent activity concentrates in Texas and Florida, with no discernible activity in other regions. The geographic and functional mismatch between the marine geophysical survey code and the work actually being procured signals that procurement offices may be applying this code inconsistently or in error; business development professionals should verify the correct UNSPSC classification with issuing bodies before pursuing opportunities nominally posted under 81151911.
